Lesson 3.8
Solve One-Step and Two Step Problems
MAFS.2.OA.1.1 (DOK 2)

2. Learning Goal
The students will use strategies for adding numbers within 100.

3. Objective
Students will be able to use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

4. Scale
3- I can, with no help, use addition and subtraction within 100 to solve one- and two-step word problems.
2- I can, with limited help, use addition and subtraction within 100 to solve one- and two-step word problems.
1- I need a lot of help to use addition and subtraction within 100 to solve one- and two-step word problems.
0- I can’t, even with help, use addition and subtraction within 100 to solve one- and two-step word problems.

5. Solve & Share pg 165
The Red Team has 15 more points than the Blue Team has 36 points. The Blue Team has 36 points. How many points does the Red Team have?
Solve and explain your answer using counters, drawings, or equations.

6. H.O.T. to consider during the lesson
1. Use context clues to identify which order of operation you would use to create an equation for the word problem.
 2. Summarize how you used the CUBES strategy to create an equation and solve the word problem. (Create Flow Chart of steps)

7. Let’s review the strategy.

8. Turn to page 166 Follow along as I read the Visual Learning Bridge.
Let’s look at problem 1 & 2 and solve the two-step problem.
1. Steve read 15 books. Sam read 9 fewer books than Steve. Dixon read 8 more books than Sam.
How many books did Sam read?
_____- _____ = ______
How many books did Dixon read?
______ + ______ = _______
1. Use context clues to identify which order of operation you would use to create an equation for the word problem.
 2. Summarize how you used the CUBES strategy to create an equation and solve the word problem. (Create Flow Chart of steps)

9. Objective reminder
Students will be able to use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

10. Kagan Structure- Think, Pair, Share
Students will count 1- 2
Students 1 will partner with Students 2.
Students 1 solve question 2.
Students 2 solve question 3.
Use accountable talk while talking with your partner. Listen to what they say to be able to retell if called on.

11. You do
Work questions 4 and 5 by yourself.

12. Exit Ticket- write in journal
Use questions 4 and 5 to answer H.O.T.S
1. Use context clues to identify which order of operation you would use to create an equation for the word problem.
 2. Summarize how you used the CUBES strategy to create an equation and solve the word problem. (Create Flow Chart of steps)

13. Rate yourself in your journal and explain why you are that rating
