# Multiplication Madness

#### 1 Hook

This set of lessons are appropriate for the beginning of a muliplication unit for grade 5 and up or towards the end of a multiplication lesson grade 4.

I make a point of really hamming it up about how difficult math can be and how these actors were famous for making simple things really funny. The more animated and enthusiastic the teacher is, the more engaged the studnets will be.

Explain to students how challenging math can be for everyone and how these two actors made fun of how complicated math can be. Show the Abbot and Costello video https://www.youtube.com/watch?v=XnICFjDn97o - this is the one where they are explaining how to mulitply 7x13.

Challenge students to create their own video to explain how to correctly multiply 7x13 and figure out where the mistakes were made. Decide how you would guide these gentlemen through the process.

#### 2 Direct Instruction

Have students work out the answer to how many vacuums each salesman has to sell, what does 13x7 actually equal and how can you figure it out. Demonstrate a few strategies. Here is also where you can decide how much multiplication practice students will need.

#### 3 Guided and Independent Practice

Have students work through the muliplication segment of this fantastic resource. Here they can practice their skills and get feedback immediately. As the teacher, you can circulate amoung students to determine how well they are doing with the concept. You can also work individually with students should they need more independent support.

#### 4 Wrap Up

Have students explain their strategy for multiplying 2 digit numbers. For your stronger students they can find another set of numbers to act out like Abbot and Costello. They can also explain where the characters were going wrong in their thinking and how the student could show them their error.
