Students need to find ways to stand and literally organize themselves into their birthday months at the front of the room.
At grades 3 to 5 – do this without talking at all.

Human Number Line

Give a number (0 to 9) each to 10 students. Can you line yourselves up smallest to largest? Find a partner so your numbers add to 10. Odd and even. Straight numbers/curved numbers. 4 and 3 - make the largest number you can, etc

Calculator, 14 -15 popsticks between each two students.
