Reply To: Lesson 5-2: Applying Different Types of Comparison – Discussion

[Aaron Davis]

Christina,

I use dot cards a lot with the interventions I have with 1st-3rd graders so the idea of using them in a different way (to promote additive or multiplicative thinking) is awesome. I often find myself trying to push the boundaries depending on the developmental readiness of the students and engage them even further with deeper prompts.

With that in mind, I can use a dot card with a group of 3 dots and compare it with a dot card that has three groups of the same group of 3 dots (so 9). With the right prompts, maybe responses could be, “B has 3 times the amount of dots than A” or “A is 1/3 the amount of B.”

Or is this a stretch?
