Put-Together Learning Problems K-51
Model "Put-Together" problems. Instead of starting with one part and adding to it, start with two parts and join them together. If there is 1 cube in one part and 1 cube in the other part, how many cubes are there in all? Since 1+1=2, there are 2 cubes in all. Use a part-total model to visually show the relationship between the parts and total.
