In this lesson, students decompose the number 8. First, they break off a part of the 8 linking cube stick and create a number sentence. Then they draw the cubes and the action they took. Next, they write the equation. Finally, students repeat the exercise several times, each time increasing the subtrahend by one until there is 8 - 7 = 1.
