Math is Visual Prompt #3: How Many Are There?

(12 apples, 18 pears, and 24 lemons are arranged in rows and columns.)

Students would be given an opportunity to do a notice and wonder with this visual. They may notice: there a greater number of lemons compared to the other fruit. The apples are the least in quantity. The fruit is arranged in rows and columns which make them easier to count. They may wonder: how many more pears are there than apples? How many more lemons are there than apples? How many fewer pears are there than lemons? We would explore: How many pieces of fruit in all?

Students would be given an opportunity to make an estimation about the total number fruit. I would then provide them with some additional information to help them adjust their estimations, if necessary.

After the students are aware of the total number of fruit and each individual quantity,

we would use the following question to explore multiplicative thinking:

How would you describe the number of lemons relative to the number of apples?

and

How would you describe the number of apples relative to the number of lemons?
