Yesterday, I was feeling hungry. REALLY hungry. All I wanted was some peas and carrots. But I had a problem. I have this special kind of spoon that I cook with, and this spoon can only hold 7 vegetables. So today, I need your help figuring out all the different ways I can put together a group of peas and a group of carrots to make 7 vegetables in total.
Define the terms:
Who has an idea for how I could figure out one way?
After one student shares a strategy, I'll have everyone “test it”. My guess is most kids will do fingers first.
Watch the video for how I did the middle portion of this lesson! Included is the chart the class made together!
Also, see the attached document for the worksheet we used.
After independent practice, we will review our learning objective and I'll have students come back and share their combinations with the class. We will create a class chart to post of all of the combinations we found.
I'll chart these combinations intentionally (similar to the way I charted them in the strategy share). I'll chart so that students will notice the commutative property. In other words, 3 + 5 will be right next to 5 +3.
After we chart all of the ways we found, I'll have students turn and talk to discuss what they notice about the combinations.
