This is a mini unit based on odd/even numbers.
This mini unit contains 1 "Lost Animals" sort. Students are asked to get the animals (with an odd or even number on it) back to its right tent at the circus. This sort contains numbers 1-50 to practice even/odd numbers. It also has a matching record sheet.
The game also practices odd/even numbers. Students can either flip a deck of cards or roll a die. Students then move forward around the board if it is even number. And backwards if the number is an odd number. The goal is to make it to 0 or 20. My students love to play this game!
