Kids go around the room, figuring out the standard form of each of their peers' numbers. They record their answers on paper next to their classmates' names. Once all numbers are figured out, have kids find the largest and smallest number. Can they identify which ones are even or odd?
You can practice any concept on a name tag: addition, subtraction, multiplication, or division. Have kids write a number sentence on their name tag. Then, they go around the room and solve each equation using a list of their classmates' names.
Kids can also work on parts of speech. Each kid has a word on their name tag. Kids have to organize themselves in the correct group. Do they have a noun, verb, or adjective?
