# Peas and Carrots...Carrots and Peas

Lesson 1 of 12

## Objective: SWBAT find combinations for 7 and 8. SWBAT use the commutative property as a strategy to find combinations.

#### Opening Discussion

*10 min*

**Present Problem:**

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:**

- Whole: I can only have 7 vegetables in my spoon. 7 is my whole, or ho w many I have in all.
- Part: I need you to imagine that some of them are peas and some of them are carrots.
- How many peas would I have? How many carrots? The number of peas is 1 part, the number of carrots is the other part of the number 7.

**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.

**Guiding Questions:**

- Are there 7 in total?
- Which fingers represent how many peas? Which fingers represent how many carrots?
- Now let’s look at it with green and orange cubes. How many green cubes do I need? How many orange?
- How many in total?

**Record strategy:**

- Think Aloud: I know that we are putting 5 and 2 together and when we put numbers together, we need a +sign, so I am going to write 5+2 next to this picture. We will put all the ways we found on our chart at the end of class.
- I will draw 5 orange cubes on this side, and 2 green cubes on this side. I am going to show how I counted them to prove that I have 7 in all.

#### Debrief and Closing

*10 min*

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.
