Examples:
1. "Why did you choose to use that strategy?"
2. "Who did it another way?"
3. "Does this answer seem reasonable?"

As a class, we will create an anchor chart to highlight the possible solutions.

This is an example of what it will look like.

Students will multiply:
2 x 4 = 8
2 x 50 = 100
20 x 4 = 80
20 x 50 = 1000
Then add the totals:
8 + 100 + 80 + 1000 = 1188

Students will recognize a method to solve two-digit multiplication

Standard: 5.NBT.5

Example Problem:

At Frog Jump, you saw 12 people in line to buy tickets to jump a frog. If each ticket costs $25, how much was it for all 12 people?

# data[].attributes.body
Students will multiply:
4 x 2 and 4 x 20 = 88
5 x 2 and 5 x 20 = 1100
Then add the totals:
1000 + 88 = 1188
