Cookie Monster Teachers CCS K.NTB.1

We said to students, "Cookie Monster is wondering if his 14 cookies will fit in his cookie box. What are you thinking?" (His cookie box happens to look just like a ten-frame...hehe)

Yes! No! No, that box will only fit 10 cookies!

How many will be outside of the box?

100!! 6! 4! 20!

Let's check...

They don't fit! Four are outside of the box!

Fourteen is ten and some more. 14 is the same as 1 group of 10 and 4 more!

We continue with other teen numbers and build a chart together over several days.

The kiddos were so engaged and really got to practice articulating their math reasoning!

More soon!
