How Many Are Hidden? A Basket of Mittens

What do you notice? How many mittens do you see?

3 pairs of mittens next to a basket. One pair has purple and orange stripes. One pair is blue. One pair is green.

Now I put some mittens in the basket.
How many are hiding in the basket?
Use math words, numbers, or pictures to explain how you know.

3 single mittens next to the basket (1 mitten from each pair).

Let’s look inside the basket. What equations match the picture? How do you know?

3 single mittens next to the basket (1 mitten from each pair). The other 3 single mittens are in the basket.

3 + 3 = 6
6 – 2 = 4
6 – 3 = 3
3 + 2 = 5

Draw a picture to show a different number of mittens in a basket. How many are left outside the basket? How many are showing?
