The method using LEGO® bricks starts with building a 10 x 10 square that has 100 studs inside the square (this is called a "decimal grid"). Each of those 100 studs represents 1/100 (one hundredth), or 0.01, in decimal notation. Within the grid, 25 studs are placed to show 0.25, and then 50 more studs are placed within the grid to show the addition of 0.25 + 0.50. It’s easy to understand that the resulting 75 studs show both 0.75 as well as 75/100, since they cover 75 out of 100 studs in the grid.
The physical nature of the Brick Math methods helps students clearly understand the underlying math. In this lesson, the relationship between decimals and fractions is obvious by looking at the model built with the bricks. As a student said, “Now I understand math. I can see it!”
If you teach math or have a student at home who is learning math, check brickmath.com. The website includes videos for both teacher training and direct instruction of students. You can learn more about how Brick Math improves student math test scores and hear what people who are using Brick Math have to say about the program.
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 are not shared between students. It adapts easily to online instruction.
