problem_activity: Narrative
The purpose of this warm-up is to elicit the idea that there can be a connection between drawings and expressions, which will be useful when students interpret the numbers and symbols in an expression in relation to drawings. While students may notice and wonder many things about the image and expression, the important discussion points are that there are 3 red counters and the number 3 and that there is 1 yellow counter and the number 1.

“How many counters are there? How do you see them?” (4. I see 1 yellow  counter and 3 red counters.)
“In the next activity, we will match expressions to drawings.”
