Two Digit by One Digit Multiplication
This lesson covers two digit by one digit multiplication but also extends to three digit by one digit multiplication. I have two videos for this skill because there are two very different methods for solving these problems. I prefer the box method because it reinforces mental math and place value. However, it will not hurt students to use the traditional method if they just cannot grasp the new way. I have added practice pages and word problems for this skill with an answer key at the very bottom of the page.
Practice Problems




Sample Word Problems:
1. Julia has $57. Charlene has 7 times as much money as Julia. How much money does Charlene have?
2. Shiza has half as much money as Andrew. Stacy has 5 times as much money as Andrew. If Andrew has $446, how much money do Shiza and Stacy each have?
3. At the flower shop, there are 8 times as many roses as sunflowers. If there are 178 sunflowers, how many roses are there?
4. Each school bus can hold 45 people. The fourth and fifth grade are taking 9 buses to the fair. How many people can ride on the buses to the fair?
