Many elementary teachers use math centers in their classrooms. They’re fun and engaging ways to review math concepts or extend instruction. However, it’s often time consuming to put them together, and they usually only cover *one* math skill.

Here’s an easy solution: ** Make 22 math centers in a matter of minutes using something I’m pretty sure you have sitting in your fridge.** Let me show you!

## Egg Carton Math Games for First Grade

#### Materials:

- egg cartons
- 3 or more marbles or small round objects
- permanent marker
- small round dot labels (optional)

#### Set Up:

All of the activities require something to be written inside each egg space. Many activities use the numbers 1-12, some use 0-9, and a few use shapes, coins, or colors. I’ve grouped the activities below according to what numbers or symbols you use.

Use a permanent marker to write the numbers inside each egg space. (Optional: Write the numbers on small round dot labels and place inside the egg carton. A bit of glue or tape is needed to hold the dots in place during all the shaking!)

#### Directions:

The steps for each of the games are the same:

- Open the egg carton.
- Place a specified number of marbles or small round objects inside and close the lid.
- SHAKE, SHAKE, SHAKE the egg carton all round!
- Open the lid. See what numbers/objects the marbles land on and perform a certain task with them.
