Area is the subject of the July 2020 Brick Math Lesson of the Month—specifically, helping students discover the formula for area using LEGO® bricks as the manipulative. It's from the Brick Math Teacher and Student Editions of Advanced Measurement and Geometry Using LEGO® Bricks.

As you read through the teacher lesson guide in the first three pages of the Lesson of the Month, you'll see that the teacher is not simply telling students the formula for the area of a rectangle. Instead, the teacher and students model a 6x8-stud rectangle with LEGO® bricks and together discuss the attributes of the shape and the two dimensions of rectangles. Students are led to understand the formula L x W = A through the process of modeling the rectangle, then drawing their model and labeling it to correspond with the formula. In this Lesson of the Month, the pages from the student workbook, with questions to answer and space for drawing the models, follow the teacher lesson guide pages.
As with all the lessons in Brick Math, this one builds deep understanding of the underlying mathematical principles. The hands-on nature of the lesson encourages the process of math discovery, which helps students learn far beyond rote memorization of a formula.
Brick Math is a K-6 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 works well for math intervention, for enrichment, and as a whole-school program. Materials are simple and need not be shared between students. It adapts easily to online instruction.

LEGO® bricks are a very versatile manipulative for math. In fact, Brick Math author Dr. Shirley Disseler has developed a method of teaching students to tell time using bricks!
The technique is called a “linear clock,” which models the numbers 1 through 12 with bricks. It works well to teach students how to tell time and how to find elapsed time. Baseplates are joined together to make the clock, and each stud on the baseplate models a five-minute increment.
Naturally, when using bricks to teach the concept of time, it’s important to also relate the linear clock to both an analog clock and a digital clock, so students learn how to tell time through conventional means.
Here’s an example of using bricks on the linear clock to show elapsed time (from Basic Measurement Using LEGO® Bricks):
Using the linear clock model, place a red 1x1 brick at 2:00 pm on the baseplate. Count forward 65 minutes, and mark the new time on the baseplate with another red 1x1 brick. What time is it now? Write a math sentence for your model.
Answer: The new time is 3:05 pm.
Math sentence: 2 hours + 65 minutes = 3 hours 5 minutes or 3:05 pm
Starting today, you can receive a FREE Brick Math lesson every month! You'll be able to download a PDF that includes the teacher instructions for a lesson, plus the student pages that go along with the lesson. It's a great way to try out the Brick Math program with your students
Once you've signed up, you'll receive a new Brick Math lesson every month.
This month, the lesson is from Basic Measurement Using LEGO® Bricks, and it's about "Coin Values." You'll use bricks to model the values of coins: pennies, nickels, dimes, and quarters. It's a simple, yet very effective, way to help students comprehend the value of each coin and how the coins relate to each other. Typically, students learn about coin values in Kindergarten or first grade.
