Taylor is trying to solve 6x8. He sketches a rectangle to help him think about how to break apart the numbers so that the fact is easier to solve. Use numbers or words to explain how Taylor can use his sketch to solve 6x8.
Taylor's rectangle is in 2 pieces. The first rectangle shows 6x5=30. The second rectangle shows 6x3=18. So the total is 30+18=48. So, 6x8=48.
