# Math Symbols

Recognize braille sign bricks. Apply math operation rules in an open-minded trial and error activity.

## Let's play!

Pick 2 bricks from the number brick bowl.

Write a 2-digit number.

Perform math operations with the other number and math sign bricks to recreate the same 2-digit number.

Place your operations on the base plate.

## How to prepare

1 base plate

Number bricks

1 number sign bricks

Math sign bricks

2 bowls

Place the number sign brick on the top left corner of the base plate to indicate the bricks represent numbers.

Place number bricks and math signs bricks in 2 different bowls.

## Facilitation tips

Reminder: explanation of the importance of the number sign in front of each operation and that there are no spaces between the bricks.

Encourage exploration of different operations to match the number. Several correct answers are possible.

Ask “What was your strategy for solving the problem?”.

## Possible variations

Change the number of bricks to be picked.

Peer collaboration : one player writes the operations and the other finds the correct answer.

Propose challenge: multiple or specific math operations to equal a number.

Find the math signs to be placed between the number bricks to equal a specific number.
