Warm Up 1. There were 4 haunted houses with 87 ghosts in each house. How many total ghost were there? 2. There were a total of 186 black cats that lived on Witch Lane. If an equal number of cats lived in each of the 6 houses, how many cats lived in each house? 3. Which table shows 4 more than 5 times the number in Set A? A. Set A Set B B. Set A Set B 1 25 1 9 3 35 3 19 6 50 6 34 4. Dr. Peter Venkman wrote down the number of ghosts at the cemetery. Then he multiplied the number by 6 and subtracted 10 from the product. The result was 62. What was the number of ghosts Dr. Peter Venkman saw at the cemetery? How can we solve a multiplication problem with a 3 digit number and a 1 digit number? Review: Solve as a class What is the equation you would use to solve this problem? 347 x 8 How could we break apart 347? 300 40 7 What are we going to multiple each part by? Add Partial Products: X8 300 X 8 2400 40 X 8 320 7 X 8 56 2400 320 + 56 2756 How can we solve a multiplication problem with a 3 digit number and a 1 digit number? Strategy Two Regrouping: 347 X 8 277 6 3 5 7 X 8? What is 40 X 8? 320 Plus 50? What is 300 X 8? 2400Plus 300?
