Lesson 2-7Problem Solving: Draw A
Picture and Write a Number Sentence
Mr. Baker2nd Grade
Today We Will Learn!
• Information in a problem can be shown using a picture or diagram and used to understand and solve the problem. Some problems can be solved by writing and completing a number sentence or equation.
Vocabulary
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?
•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.
