Try this with your students, at home or in the classroom (or in the virtual classroom). This system of representing decimals with bricks is a great way to reinforce the idea of decimals.
The lesson starts with the Teacher's Lesson Guide. All the steps for teaching students how to model several different decimals are included. The corresponding pages from the Student Workbook follow, with space for the student to write responses as well as draw the models they have built.
The illustration below shows, on the left, the brick model for the decimal 0.23, and on the right, a drawing of that same model.
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 homeschooling, math intervention, enrichment, and as a whole-school program. Materials are simple and are not shared between students. It adapts easily to online instruction.
