Practice math concepts with LEGO® bricks! These printable math challenge cards will have kids exploring number concepts in a fun and hands-on way. Print them, add a basket of bricks, and you have an instant math center!

I created them with 6-8 year olds in mind, or first and second grade. They will be too challenging for most first graders at the start of the school year, but will be suitable for the second semester or for kids who need more of a challenge in math. (Maybe a center for kids who finish their work early?) Second graders should be able to master the concepts.

**Math concepts included in the challenge cards:**

- Addition
- Subtraction
- Fractions
- Measurement
- Estimation
- Place Value
- Grouping – helpful for understanding the concept of multiplication

**There are 54 cards to print. Here are some examples.**

Fractions – 1/3 of 12 is how many bricks?

Place value – Build 46 as 10’s and 1’s.

Grouping – Build 4 groups of 7. How many bricks is that in all? 7 + 7 + 7 + 7 = 28, or four 7’s equals 28. There are also cards that present the concept from the opposite angle. For example, grab 25 bricks. Make groups of 4. How many groups can you make? How many bricks are left over?

This type of thinking prepares students for multiplication and division.

**What bricks do I need?**

I would recommend setting out at least 50 2 x 2 LEGO® bricks, although 4 x 4 bricks will work too. Most of the cards do not require a specific color, but the fraction ones do. It would be good to have at least 10 bricks in yellow, red, green, and blue. If you are planning to have more than one child working on the challenges at one time, you’ll want to have more than 50 bricks. 100 would probably be enough for three kids or so… since I’m not a classroom teacher it’s hard to say! Leave a comment if you have helpful feedback to offer after trying this with a class!

**Printing Tips: **I recommend printing these on card stock for better durability. Or, laminate your cards. Make sure that your printer is set to NOT print two-sided.
