Is there a kid alive who doesn’t love LEGOs? If so, we sure haven’t met them. These beloved building bricks make terrific tools in your classroom, and they’re especially great for teaching a variety of math concepts. We’ve put together this list of our favorite LEGO math ideas for every skill level. Your students are going to love them!

1. Learn your numbers.

Lego Math

Start simple with these free printable LEGO math mats. Kids align the bricks as shown to make a numeral, then lay out the appropriate number of bricks below it.

2. Race to 20 to practice counting on.


This activity is great for 2+ players. Write the numbers one to twenty (one number each) on the flat side of 20 LEGO (or DUPLO) bricks with wet-erase markers. Kids start with the brick labeled “1” and roll a die. They add the indicated number of bricks to their stack in the correct order, racing to see who can be the first to get to 20. You can expand this game to include as many bricks as you have available!

3. Skip count with LEGO math (Method 1).

Use the same stack-and-count activity as above, but change the numbers to work on skip counting by 2, 5, 10, or whatever you’re currently working to master.

4. Skip count with LEGO math (Method 2).

Here’s another way LEGO math can be used to learn to skip count. Use the number of studs (the small raised circles) on each brick as markers while you count. It’s easy to find bricks with one, two, three, four, five, six, eight, and ten studs, so this works across a wide range.

8. Toss bricks for more place value practice.

LEGO Place Values

Make a target from paper, labeling the rings with place values. Students (gently) toss a brick of their choice onto the target. Then they use the number of studs on each brick along with its place value to create a final number. Largest number wins!

9. Use LEGO math to practice addition facts.

Lego Math

These are so much more fun than traditional flashcards! Grab your free printable set at the link and use LEGO math to practice basic addition facts.

10. Put together addition fact puzzles.

Think of this as a version of dominoes. Tape a math fact card to each brick. Kids look at the top number, then look to find the brick with the equation that has that sum as the answer. They continue on, stacking bricks as they go.

11. Roll a die to subtract bricks.

This is basically the opposite of Race to 20 (above). Start with a given number of bricks stacked into a tower. Roll a die and remove that number of bricks, stating the new number that remains. Players race to be the first to remove all their bricks. Make it more challenging by requiring the last roll to be the exact number needed to get to zero!

15. Teach multiplication arrays with LEGO math.

Lego Math

Teaching multiplication using arrays is so easy with LEGO bricks! Use a single brick and count the studs across and down. You can also group multiple bricks together for larger arrays.

16. Multiply bricks for fact practice.

LEGO Arrays Multiplication

Students grab several bricks of the same type, then multiply the number of studs by the number of bricks. This kind of LEGO math sneaks in some subitizing practice too.

17. Visualize multiplication with LEGO brick stacks.

If your students are struggling with the concept of multiplication, this sort of visualization activity can be a real help. It brings the multiplication table into the 3-D world!

25. Put area and perimeter into practice. 

LEGO Area Perimeter

The studs on LEGO bricks make it simple to find the perimeter and area. Start with individual bricks, then increase the challenge by throwing more bricks into the mix. There are a lot of fun options here.

26. Build a model room.

Ready for a bigger geometry challenge? Let kids design and build a model room full of furniture. Chart it out on graph paper first, then put it into practice.

27. Discuss mean, median, and more.

LEGO Mean Median Mode Range

There are a variety of ways to use LEGO math with mean, median, mode, and range. Here’s one idea: Set a timer and have kids build the tallest tower they can before the time runs out. Then, they take their tower apart and classify their bricks by color. Using their data (ex: 19 red, 10 blue, etc.), they figure out the m, m, m, and r for their LEGO colors.

28. Map it out on a coordinate plane.

Gather up all your mini-figs and have some coordinate plane LEGO math fun! The link below has a variety of activities for this concept.
