Place 10 red cubes. Next, replace 2 of the red cubes with blue cubes. There are still 10 cubes in total. Move the cubes into a tens frame. Notice that starting with 8, it takes 2 more to make 10. In a new tens frame, place 3 red cubes. Think about how many more cubes it takes to make ten. Count the number of open spaces to see that it takes 7 more cubes to make 10. So 3 + 7 = 10.
