Let's Talk About Multiplication Goal: for students to explain their math process and gain a visual understanding of their solutions. Using Pear Deck, students will have an opportunity to talk about, draw, and reflect on one & two-digit multiplication. The questions in this lesson are based on activities and research done by Jo Boaler.

Task #1 Without using a pencil & paper, your task is to solve: 18 x 5. Add a video response explaining exactly how you came up with your answer.

Task #2 Using the drawing tool, create a visual representation of the solution you came up with in the last slide. Remember, the problem was to solve: 18 x 5.

Sample Solutions: Task #1 & #2 In the video below, you will hear from some students at Stanford and learn about how they approached this problem:

Reflection Question First of all, do you see that you were able to solve a problem that Stanford University students had to think about? That's pretty amazing, isn't it? Now that you've heard from students at Stanford, have your thoughts on your solution or your process of coming up with the solution changed? Did you learn anything new from the video responses? What confused you about the video responses?

Visualizing Math Solutions Math is a very visual language. Once you begin to see it, you begin to truly understand it! Let’s work on visualizing some multiplication concepts!

Modeling Multiplication Here is a visual representation of the number 36. 36 is 9 x 4. One way to see this, visually, would be 9 sets of dice, with the 4 facing up. That’s what 9 x 4 represents. Nine sets of 4’s. Count them all up and you get 36!

Task #3 a Now it’s your turn. Fill in the right column of the chart with images to show two numbers that can be multiplied to come up with the number in the left of the chart. Look at the "image bank" to spark some ideas & then fill in the chart with (Note: there is more than one correct answer. ) appropriate visual representations of the products.

Task #3 b Now it’s your turn. Fill in the right column of the chart with images to show two numbers that can be multiplied to come up with the number in the left of the chart. Look at the "image bank" to spark some ideas & then fill in the chart with (Note: there is more than one correct answer. ) appropriate visual representations of the products.

Task #3 c Now it’s your turn. Fill in the right column of the chart with images to show two numbers that can be multiplied to come up with the number in the left of the chart. Look at the "image bank" to spark some ideas & then fill in the chart with (Note: there is more than one correct answer. ) appropriate visual representations of the products.

Wrap Up Assessment Create a video response talking about how this activity has made you think about multiplication problems differently.
