PART I—Alfonso solved a division problem by drawing an area model. What division problem did Alfonso solve?
PART II—Show a number bond to represent Alfonso’s area model. Start with the total, and then show how the total is split into two parts. Below the two parts, represent the total length using the distributive property, and then solve.
