Since subtraction means separating sets, students model the starting number only.

They draw dots on a second ten-frame to represent the quantity to be subtracted.
6© 2012 •KP Mathematics
They cover the dots with tiles taken from the starting number.

The upper ten-frame shows the result. Students see that 9 – 3 is equivalent to 6.
