You have learned that using objects can help you solve math
story problems.
Today, you will learn a new problem solving strategy.

STRATEGIES:doubles doubles plus one
making 10
Which strategy can you use to solve these problems?
4 + 4 = 8 + 7 =
4 + 6 = 9 + 9 =

The Problem!!• Suppose Jill dropped 10
counters on the workmat and 2 landed in the first box, 1 landed in the second box, and 3 landed in the third box. The others landed off the mat.
• How could you use counters and a number sentence to find how many landed on the mat?
![Page 9: Lesson 2-7 Problem Solving: Draw A Picture and Write a Number Sentence Mr. Baker 2 nd Grade.](https://reader030.fdocuments.us/reader030/viewer/2022032611/56649ef25503460f94c03712/html5/thumbnails/9.jpg)
•2 landed in the first box. So let’s put 2 counters in the first box. 1 landed in the second box so let’s put 1 counter in the second box. 3 landed in the third box, so put 3 counters in the third box.
LET’S SEE!
•What number sentence can we write to show this problem?

• Use your workmat.
•Drop your counters on the mat.
•Try to get as many in the boxes as you can.
•Record your results on your workmat for numbers 2 and 3.
