Some students who have mastered the concepts of addition and subtraction lose their way when they try to learn division. Many math textbooks don’t help students learn division.
Students learn the concept of division best through the process of modeling with manipulatives. Brick Math uses manipulatives that kids love: LEGO® bricks! With Brick Math, students create models that help them understand the concepts behind division.
Brick Math helps students learn division through an integrated program. The teacher uses the step-by-step lesson plan to show students each concept. Then students create brick models of the math as they learn. They draw the models they’ve created and explain in writing what the models mean. These three different ways of interacting with bricks lead to a deep understanding of division.
The Brick Math Division book uses a step-by-step approach to break down these division concepts into learning modules:

When students model the action of division using bricks, they have the opportunity to create multiple solutions to problems instead of looking for one right answer.
Brick Math is fun! Students love learning math with bricks. A teacher said: “My students would rather do Brick Math than go to recess! They love it!”
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!

We like to think of Brick Math as the Swiss Army Knife of educational programs. It’s a versatile teaching tool that works in many different settings.
Whole class: The Brick Math program can be introduced to the whole class by the teacher. In fact, many schools have adopted Brick Math as their elementary math curriculum across the school. Once teachers get accustomed to using the LEGO® bricks as the manipulative tool, they recognize the power of the build-draw-explain Brick Math lesson plans. The teacher works through the lessons in each book, having the students build models at the same time. A document camera is a great help for displaying the brick models to the whole class so everyone can see them. Students share brick sets in pairs and often work together in the lessons, comparing their models and explaining their thinking processes to each other. The Student Edition makes it especially easy for teachers to assess and track students’ progress.
Small Group: Brick Math is often used by a school math specialist in a small-group setting. It’s very well suited to the interactive nature of small group learning.
Intervention: Schools are discovering the value of Brick Math as the perfect tool for math intervention. The modular components of the Brick Math system allow the program to be introduced at any point where a student is having difficulty learning through the school-wide math textbook curriculum. Time and time again, students who have been struggling with learning a concept such as fractions, for example, are successful with the Brick Math approach. We’ve heard kids make comments like: “Finally! I understand the math because I can see it!” and “Why doesn’t everyone learn math this way?”
Gifted: As useful as Brick Math is for students who aren’t learning math through other teaching methods, it’s also great as enrichment for students who already understand and love math.
Centers or One-to-One: Students really enjoy the hands-on nature of Brick Math, making it very adaptable to one-to-one learning or individual centers.
Like the Swiss Army Knife, Brick Math has something for everyone!
High Point University, home of Brick Math author Dr. Shirley Disseler, celebrated International LEGO Day yesterday, encouraging HPU students to come to the Stout School of Education and build something out of bricks that they are passionate about.
Dr. Disseler is passionate about using the bricks to help students learn math. Her Brick Math curriculum for elementary and middle school was developed to help students conceptualize math, or, as Dr. Disseler says, "to understand the why behind the math."
Here's the full article about International LEGO Day at HPU, courtesy of the HIgh Point Enterprise.
A new mixed-method study shows significant gains in test scores for math content in grades K - 2 after instruction using Brick Math. The findings from a new study of 500 students in kindergarten, first grade, and second grade shows that 320 of the 500 students, or 64 percent, made pre-to-post assessment gains of 4 or more points on a 10-point scale.
Each student was given ten problems to complete, in writing or orally, in the areas of counting and cardinality, addition, or subtraction prior to being taught with the Brick Math methods. The same problems were then used with the Brick Math program. Before starting Brick Math, students were asked questions about why they responded in certain ways to the problems to help the researcher identify misconceptions held by students about number sense and computational understanding. Once the problems were completed using the Brick Math methods, the problems were again scored on a scale of 1 - 10 (correct versus incorrect).
Students were then asked to discuss the meaning of the models with the researcher. Students were also encouraged to ask questions for clarity during the teaching process. The discussion of the models yielded some important information about how students learn and understand math. Students in kindergarten made comments such as: “Now I see why 8 is larger than 3,” and "5 is between 3 and 8.” Students learning about place value said, “Counting bricks in the tens and ones place helps me know what number goes in each place.” A student further explained, “Two 1x2 bricks and four 1x1 bricks show that the tens place is 2 and the ones place is 4, and the whole number is 24.”
This study was conducted in public and private school classrooms in New Jersey and North Carolina, in rural, suburban, and urban settings for 150 kindergarten, 200 first grade, and 200 second grade students.
Data and Findings:
The data was analyzed using a one-way ANOVA from SPSS, which indicates that achievement was statistically significant across all three grade levels and all content materials. A Pearson correlation shows no significance between the performance of girls versus boys. This finding is interesting, in that many believe LEGO® bricks are preferred by boys. In this study, the girls did as well as the boys in achievement when using Brick Math. The variables measured in the study included: focus and body language when using Brick Math, verbal participation and questioning by the student, the degree to which students were able to make conceptual meanings in the models, performance pre to post (before Brick Math instruction and after Brick Math instruction). It was interesting to note that the degree of focus was significant (p = 0.03) upon introduction of the bricks to do the math problems. The findings also suggest that both the level of performance and the degree of perseverance are directly related to the degree to which the student could focus (p < .05) in all correlations of these variables. The median pre- to post-difference in the study across all groups was 4 with a range from 0 – 10.
The means are displayed for each grade, pre and post, in Table 1. The spread of the mean shows wide differences before and after the instruction in each of the three grades, with the largest difference found in grade 2.
Table 1: Comparison of Means Pre-to-Post by Grade Level
Grade N Means
K 150 3.3600 7.2667
1 150 4.0467 7.6133
2 200 3.6050 8.0300
The modeling of math offers students a way to connect, but when LEGO® bricks are introduced as the medium for learning content, students become enthusiastic, focused, and engaged, which leads to motivation and time on task. Education experts agree that motivation and engagement are the two key elements in getting students to learn. This study is part of a larger study being conducted to emphasize the value of Brick Math in elementary and middle school math classrooms. This study, which utilized Brick Math as both a guided math and whole class lesson, points to positive learning gains for children in the early years of elementary math. Setting the stage for more sophisticated math content, getting students to understand the “why” behind the basics of math is a key component necessary in early stages of math learning. If students can build a model of the problem and solution, and explain verbally or in writing the “why” behind the math, the likelihood of future success in both their opinions about math and their ability to persevere in dealing with more difficult math will be greatly enhanced.

Teaching students to add fractions that have unlike denominators can be a challenge. It starts with teaching how to find a common denominator. Far too often, this can lead to a purely procedural account of the how, but not the why behind the math. Using LEGO bricks to teach this concept brings new understanding of the term “common denominator” by providing a visual and tactile link.
A key piece of knowledge when comparing fractions concerns understanding same-sized wholes. Students often make errors when trying to add or subtract fractions because they don’t grasp the concept that fractions can only be compared if the whole (the denominator) for both fractions is the same size.
Let’s add the fractions 1/4 and 1/3 together to show how the process works. First, build models of the two fractions on a baseplate using LEGO bricks. Model the fraction 1/4 with a 1x1 brick and a 1x4 brick, placing the 1x1 brick above the 1x4 brick. Model the fraction 1/3 with a 1x1 brick and a 1x3 brick in the same way. Build the 1/3 fraction model next to the 1/4 fraction model, leaving a little space between them, as shown.
In algebra, we use the phrase, “What you do to the left you must do to the right,” to help remember how to approach equations. Here we say, “What you do to the bottom you must do to the top,” to remember that the way you treat the denominator defines the way you treat the numerator. The fraction train shows the multiplication that takes place as you build the common denominator model. Note: As you build the fraction train, you distinguish between counting bricks and counting studs.
To build the fraction train, find another 1x4 brick and place it on the baseplate below the two fraction models. Then find another 1x3 brick and place it just underneath the 1x4 brick.
This begins the fraction train and represents the two fractions in the order they appear in the equation: 1/4 + 1/3 = ____. Add another 1x4 brick to the train, and then another 1x3 brick to its train. Continue adding 1x4 bricks to that train and 1x3 bricks to the other train until both fraction trains of bricks are the same length. Ask students to count the number of studs in each line when they are equal in length. (Answer: 12.)
This is the common denominator. Place a 1x12 brick at the bottom of the baseplate to represent the common denominator of 12. This is part of the solution model.
Now it’s time to determine the numerators, based on the common denominator. Start with the 1/4 fraction. Look at the fraction train built by the 1x4 bricks and ask: “How many 1x4 bricks are in the train?” (Answer: there are 3.) Now look at the model of the fraction 1/4 and ask: “What brick represents the numerator of the fraction 1/4? (Answer: the 1x1 brick.) Remind students that what you do to the bottom you must do to the top. Since there are three 1x4 bricks in the denominator, there must be three 1x1 bricks in the numerator of the solution. Place three 1x1 bricks above the 1x12 brick that represents the common denominator in the solution.
Repeat the process for the fraction 1/3 by counting the number of 1x3 bricks in the fraction train. (Answer: there are 4.) Since there are four bricks, place four 1x1 bricks in the solution model next to the three 1x1 bricks you just added.
Count the number of studs in the numerator: 7
Count the number of studs in the denominator: 12
The solution: 1/4 + 1/3 = 3/12 + 4/12 = 7/12
When you take students through the modeling of the solutions, you give them a powerful way to visualize what common denominators look like. Creating and modeling same-sized wholes (the fraction train that shows the common denominator) with LEGO bricks is key to understanding how to add unlike fractions. For both visual and tactile learners, this method helps students understand the multiplication process utilized with fractions, as well as the relationship of same-sized wholes and common denominators.
