“I learned a new way to divide large numbers,” Luis explained. “I want to practice it. It’s called box division.”
Luis drew a rectangle on the sidewalk. He divided it into three columns.
At the top of each column, he wrote the digits 8, 6, and 8. To the left, he wrote the number 7.
“You use multiplication and subtraction to find your answer,” Luis explained.
“That’s very cool,” Caleb said. He watched Luis work. Luis wrote subtraction signs and arrows in the box. Finally, Luis circled the numbers at the bottom.
“We each get 120 pieces of candy!”
The friends poured all the candy out of their bags. They piled it next to the chalk grid. Then each person picked 120 pieces to keep.
“118, 119, 120!” Hiro finished. He held up his full bag. He smiled. “That’s so much candy! Splitting up was a great idea, Luis.”
