? Students will need a blue coloring pencil or marker (if you do not have a blue coloring pencil, then you can use a different color or have students shade in the boxes with their pencil).

? This activity works great individually or in pairs.

? I like to go over the difference between rationals and irrationals with students before they start coloring.

? The answer key is provided on page 5.

? As always, I appreciate it when you leave feedback!

? If you have any questions or would like me to make a custom worksheet for you, please email me at mathindemand@. Thanks so much!
