To celebrate "The Year of Brick Math," we're adding a new feature to the free Brick Math Lesson of the Month  video! Dr. Shirley Disseler, author of the Brick Math curriculum, demonstrates the April 2021 lesson in a fiveminute video that shows the concepts for comparing and ordering 3 fractions with unlike denominators. To get the April 2021 lesson, "Comparing and Ordering Fractions," and a link to the video lesson, plus a new lesson each month, sign up here. Elementary school math teachers know how tricky this skill can be for students to comprehend. When they look at the fractions 1/2, 3/8, and 3/4, many students will think that 3/8 is the biggest fraction of the three, since the denominator is the largest number. This lesson demonstrates the "fraction train" method of finding a common denominator using LEGO bricks to build the fraction models and model the equivalent fractions. This lesson is from Chapter 7 of Basic Fractions Using LEGO Bricks in the Brick Math series. Students typically learn this skill in grades 3  4. Modeling the math with bricks makes it easy to learn. Try the free lesson with your students to see how much fun it is to learn with Brick Math!

This lesson teaches students about the factors of 16. To get the March 2021 lesson, and a new lesson each month, sign up here. This might be my favorite lesson in the entire Brick Math curriculum, because it does so many things so well:
I use this lesson often when I’m demonstrating how well Brick Math works as a complete learning solution for elementary math. It always helps someone new to the program understand how effective the Brick Math methods are. Try the lesson with your student(s) today to demonstrate factors. The first two pages are from the Teacher Lesson Guide. The next two pages are for the student to use as they learn. There is a baseplate on the last page where the student can draw his/her final model of the factors of 16, plus space to list all the factors of 16. We guarantee they will have that “aha” moment when you teach factors this way! Brick Math’s Basic Fractions Using LEGO® Bricks is a great way to get started with the topic of fractions. It starts by teaching the concept of fractions and progresses through unit fractions, addition and subtraction of fractions, and both like and unlike denominators. The use of LEGO® bricks to model the math makes it fun to learn, too! Brick Math is a K6 math curriculum that uses LEGO® bricks to model 11 different math subjects: Counting, Addition, Subtraction, Multiplication, Division, Basic Fractions, Basic Measurement, Fraction Multiplication, Fraction Division, Advanced Measurement and Geometry, and Decimals.

It’s been well established that fractions are tough for many students to learn. And it’s also clear that fractions are a very important building block for learning the higherlevel math that follows, including decimals, ratios, and algebra. So we need a learning system that helps students achieve a deep understanding of fractions, not simply a regurgitation of some formulas or tricks. Luckily, Brick Math: Teaching Math Using LEGO Bricks includes techniques that really work when teaching students what fractions are all about. Here are four ways you can make it easier to learn fractions (all the illustrations and techniques here are from Brick Math's Basic Fractions Using LEGO Bricks–Teacher Edition): 1. Math is conceptual, so a student first needs to understand the idea of a fraction. The best way to learn that is by providing a visual presentation of a fraction. Brick Math, which teaches math using LEGO bricks as the modeling tool, is the perfect way to show what fractions are. A 1x1 brick next to a 1x2 brick clearly represents a fraction of 1/2. A LEGO brick with 2 studs next to a brick with 4 studs? Clearly showing 2/4. A fourstud brick next to an 8stud brick models 4/8 without question. The studs on a brick are easy to count, even for young learners, and there is no mistaking the fraction that the bricks are showing. 2. Fractions refer to parts of a whole, but the whole must be defined clearly to understand the size of the fraction. The techniques used in Brick Math work well to clarify the concept of the whole. If the whole is 8, the brick that represents ½ of that whole has 4 studs. But if the whole is 6, the brick that represents ½ of that whole has 3 studs. LEGO bricks demonstrate this idea clearly. 3. Adding and subtracting fractions relies on students’ knowledge of multiplication. To find a common denominator, a student must have memorized multiplication tables to understand the idea of factors. That’s a hurdle many students have trouble with. But factors are easy to show with Brick Math. Students discover factors for themselves by manipulating the bricks. The illustration here shows all the factors of 8 in a way that students can immediately grasp (8, 4, 2, and 1). 4. It can be hard to understand how to put fractions in order. What’s bigger: 2/3 or ¾? That question becomes easy to answer using the Brick Math technique called the “fraction train.” That’s a way of modeling equivalent fractions with common denominators to visually demonstrate which fraction is larger. (Spoiler alert: ¾ is larger, because it is equivalent to 9/12, while 2/3 is equivalent to 8/12.) There’s so much that’s hard about learning fractions. Brick Math makes the learning process easier so students can develop deep understanding of the math. That’s the key to future math success.

Contact us with any questions. I recently had a customer tell me that her son didn’t understand the idea of factors until she tried Brick Math. When he saw the concept of factors made real with LEGO bricks, she said, he knew what they were! It’s exciting to hear when students finally “get it” because modeling with bricks makes all the difference for them. I started to think about that lesson on factors, and I realized it is the perfect way to demonstrate the power of Brick Math as a learning system. Here’s why Brick Math works so well to teach elementary math: it’s tactile (kids touch the bricks and build the models themselves), it’s visual (kids can see exactly what the numbers in a math problem represent), and it’s conceptual (kids understand the underlying idea behind the math when they discover it for themselves in a guided program). Let me show you how Brick Math works with that lesson on factors: This lesson models all the factors of 16 and demonstrates perfectly the meaning of “factor." Like all Brick Math lessons, it starts with some basic bricks and a baseplate to build on. Begin by placing one brick that has 16 studs on the baseplate (studs are the bumps on LEGO bricks). This can be a 2x8 brick or a 1x16 brick.The model shows 1 brick with 16 studs, so the multiplication fact shown is 1 x 16 = 16. 16 and 1 are factors of 16. Next, take two bricks that each have 8 studs and place them next to the brick that’s already on the baseplate. It’s best if those two bricks are two different colors. You’ll use either two 2x4 bricks or two 1x8 bricks. Now the model shows 2 (bricks) x 8 (studs) = 16, and that 2 and 8 are also factors of 16. Now, here’s where the Brick Math program really becomes a powerful learning tool. For the next step, ask the student, “Are there 3 bricks that are all the same size that you can use to build the next row?” Let your students try with different bricks. They will demonstrate to themselves that there are none, so 3 can’t be a factor of 16. It’s so important that students discover for themselves while they are learning. That’s what helps them internalize what the math is all about. When they move on to looking for 4 bricks, they’ll find that four 2x2 bricks or 1x4 bricks do the trick. Now, they have 4 (bricks) x 4 (studs) = 16, so 4 is another factor of 16. Have them look again for 5, 6, and 7 bricks that work in the model. They’ll quickly figure out that none of those numbers are factors of 16. They’ll move on to modeling eight 1x2 bricks, with the multiplication fact of 8 x 2 = 16. Finally, they can add sixteen 1x1 bricks to the model to complete all the factors with the multiplication fact of 16 x 1 = 16. When you look at the final model and count the number of bricks, the final model clearly shows the factors of 16: 1, 2, 4, 8, and 16. Dr. Shirley Disseler, developer of the Brick Math method, demonstrates this same lesson in the video below. The concept of factors is key to learning multiplication, division, and fractions, so it’s in all three of the Brick Math books on those subjects: Multiplication, Division, and Basic Fractions. And it (almost) goes without saying: students have fun while they learn! If you teach math or have a student at home who is learning math, check brickmath.com.

For September, it's a lesson from Fraction Multiplication Using LEGO® Bricks that shows how the commutative property works when multiplying fractions. Students typically learn about multiplying fractions in grades 4  6, but it is sometimes part of the curriculum when students are learning about fractions in grades 2  3. To get the free Lesson of the Month for September 2020, click here. Students should already understand that a x b = b x a (see Multiplication Using LEGO® Bricks, chapter 5). Now it's time for them to learn that the same commutative property holds when multiplying fractions. This lesson makes it clear to students by using bricks one way to model 1/2 x 6, and a different way to model 6 x 1/2. In both cases, the answer, 3, is the same. This lesson also shows how the two number sentences are used to describe different reallife situations: 1/2 x 6 means "onehalf of six," while 6 x 1/2 means "six sets of onehalf." So in reallife usage, 1/2 x 6 could describe "half of the six crayons in the box, or three crayons." And 6 x 1/2 could describe "six halfpizzas, or three whole pizzas." Using bricks to model these two scenarios really helps students understand the math.

The concept of Least Common Denominator (LCD) is key to being able to add and subtract with fractions that have unlike denominators or compare the size of different fractions. It's essential for students to thoroughly grasp the idea, and until they do so, they can't move forward with fractions. Modeling with LEGO bricks is the perfect way to teach students how to find the least common denominator. This method from Brick Math, called the "Fraction Train," starts with concrete representation of the math problem using bricks, to teach students exactly where the idea of a common denominator comes from. 1. Start by explaining that the process for finding Least Common Denominator with bricks is called the "Fraction Train." Have students build brick models of 2/3 and 3/4. Label them Fraction 1 and Fraction 2. 2. Discuss the value of the numerators and the denominators of 2/3 and 3/4. Ask students if the wholes are the same, and if not, which whole is larger? Explain that you will be finding the Least Common Denominator so you can compare the fractions. 3. Place one 1x3 brick on the baseplate, showing the denominator of Fraction 1, and under that, a 1x4 brick showing the denominator of Fraction 2. Now it's time to start building your "fraction train." You'll be building out a train of bricks that makes a rectangle. Add enough 1x3 bricks to the top row, and enough 1x4 bricks to the bottom row, until both rows are the same length and the bricks form a rectangle. Count the studs in each row (12) to find the Least Common Denominator—the smallest number that both denominators can divide into evenly. Discuss the fact that 12 is also the equivalent whole for both fractions 2/3 and 3/4. 4. Now it's time to build the equivalent fractions for 2/3 and 3/4, using the Least Common Denominator of 12. Place two 1x12 bricks on the baseplate to represent the LCD of 12 for each fraction. 5. Look at the fraction train again. There are 4 bricks in the top row of the fraction train. This shows the number of 1x2 bricks (from the numerator of Fraction 1) that will model the numerator of the equivalent fraction. Count the studs in the numerator (8) and the denominator (12) . This shows that the equivalent fraction for 2/3 is 8/12. 6. Repeat the process for Fraction 2. Count the studs on the model of the numerator (9) and on the denominator (12). The equivalent fraction for 3/4 is 9/12. 7. Now the equivalent fractions can be compared, since they both have the same denominator. Have students look at the numerators of each fraction and determine which fraction is larger, based on having the larger number of studs in the numerator. Extend the learning by having students draw their models. Have them write a math sentence that compares the two fractions (2/3 <3/4 because 8/12 < 9/12).

Whether you are a longtime LEGO® fanatic or new to the wonders of the plastic brick, it’s not hard to understand how well LEGO bricks work as a tool to teach fractions. The bricks can easily show concepts of benchmark fractions (½, ¼, 1/8, etc.), and since many students are familiar with them as a toy, they really enjoy using them in math class. Brick Math’s Basic Fractions Teacher Edition has a full curriculum for teaching fractions using LEGO® bricks. It starts with activities to answer the question “What is a fraction?” and moves through all the fraction topics – benchmark fractions, adding and subtracting fractions, factors, equivalent fractions, finding common denominators, and mixed numbers. Benchmark fractions (½, ¼, 1/8, ¾) are important for students to learn early on in their exploration of fractions. These are fractions they will see often, and understanding their value will help them make estimates in reallife situations. Benchmark fractions will also help students recognize that fractions are made from differentsized wholes. This is key to understanding fractions. Here’s how to teach benchmark fractions using the Brick Math technique: 1. Start by placing a 2x4 LEGO® brick on a baseplate to represent the whole. Make sure students know that because there are 8 studs on this brick, it represents the whole of 8, and that is the denominator of the fraction. 2. Have students find a brick that shows ½ of this whole. Have them look for two bricks that are the same size and together take up the same space as the whole 2x4 brick when placed together. They should find either two 2x2 bricks or two 1x4 bricks. Explain that one of these bricks represents ½. The 1x4 or 2x2 brick has 4 studs, so the brick shows the numerator 4 of the fraction modeled here – 4/8 (or ½). 3. Ask students to find ¼ of the whole of 8 in the same way, with four bricks that take up the same space as the 2x4 brick. They should find four 1x2 bricks, and understand that one of these bricks shows ¼. With 2 studs on this brick, it models the numerator of the fraction 2/8 (or ¼). 4. Have students do the same process to find the brick that represents 1/8. Then have students place these benchmark fractions bricks next to each other, to show the whole, ½, ¼, and 1/8 – and that each fraction is half of the one preceding it. 5. To show ¾, have students look for the brick that shows ¼, then find three of them and put them next to the whole. See if your students make the connection to the 6 studs on these bricks as the numerator of the fraction 6/8. They’ll do this by showing that the three ¼ bricks are equivalent to one 2x3 brick. Brick Math is a complete K – 6 curriculum that uses LEGO® bricks to teach math. Besides Basic Fractions, Brick Math topics include: Counting, Addition, Subtraction, Multiplication, Division, Basic Measurement, Fraction Multiplication, Fraction Division, Advanced Measurement and Geometry, and Decimals.

To download the free lesson, click here. Learning fractions is difficult for many elementary school students. Even those who have succeeded in learning other math concepts may come up against a roadblock when they start to learn fractions. Research shows that the best way to learn fractions involves modeling fractions with manipulatives. Brick Math is the perfect way to learn fractions, because the manipulatives used in Brick Math are LEGO® bricks! Brick Math helps students learn fractions through its integrated program. The teacher leads students through stepbystep lesson plans. Using the bricks, students create models of the math as they learn. They then draw the models they’ve created and explain in writing how the models work. These different ways of interacting with the bricks lead to a deep understanding of fractions. Brick Math gives students the opportunity to create multiple solutions for problems instead of looking for only one right answer. Students who haven’t been able to understanding fractions before will learn fractions with Brick Math. The video below shows a Brick Math lesson about adding fractions with like denominators.
