Learning Intention: To use the concept of part-part-whole when adding things together.
Activity: Divide your mini whiteboard into three sections: part, part and whole.
Roll two dice. Using materials such as Lego, buttons or pasta, make the first number in the first “part”. Then make the second number in the second “part”. Move all the objects into the “whole” section of the whiteboard and count all the objects. How many altogether? You can also use two playing cards instead of dice.
