I don't know about you but my students have needed a LOT of hands-on and visual help learning odd and even numbers. I created this set of odd and even manipulatives to give them that little extra support that they needed as we started learning this concept. Just cut out, print on card stock, and laminate for durability. Each student gets their own baggie of manipulatives to use when they are determining if a number is odd or even. The hanging block of the odd numbers should be obvious to even the most naive learners.
