Lesson 15 Estimation Exploration
Let’s create an Estimation Exploration.
Warm-up Estimation Exploration: Umbrellas
How many umbrellas are there?
Record an estimate that is:
too low | about right | too high |
|---|---|---|
Activity 1 Design Your Estimation Exploration
Find an image that would encourage your classmates to estimate the total number of an item using strategies for multi-digit multiplication.
Fill in the possible estimates students might make.
Record an estimate that is:
too low | about right | too high |
|---|---|---|
Activity 2 Facilitate Your Estimation Exploration
Display your image for your classmates.
Ask them, “What is an estimate that’s too high?” “Too low?” “About right?”
Give them a minute of quiet think time.
Give them a minute to discuss together.
Have them share estimates.
Record their ideas.
