Math tub idea: Get two ice trays from the dollar spot at Target, write 2-digit numbers on white labels for each hole, and kids toss a cube in each tray and add numbers together on recording sheet or whiteboard. They think it's so fun!!
Beaded number rods for subtraction! Great visual for students with special needs. Adding concrete materials when performing simple operations, helps build number sense to ensure students are relating quantities to symbols (numbers).

i liked the idea of this manipulative using colored counting cubes to teach kindergarten students to add small numbers by using a color for the first number and a different color for the second number then add them together to find out the sum by counting all the cubes together.
