2.OA.1. 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.1

Introduction/Problem:
How to solve multi-step word problems.

Procedures:
TTW model using Kidspiration math view. TTW model clicking on use steps in math view and discuss how to pick which manipulative to use. For most 2nd grade multistep problems the students will want to use tiles or base ten blocks. TTW model solving a multi-step problem such as: Cindy had 18 pieces of candy. She ate six pieces in the morning, and four more pieces in the afternoon. How many pieces of candy does she have left? TTW model putting out 18 pieces of candy. Then creating a new step and putting 6 into a circle labeled morning. Then create a new step and put 4 pieces into a circle labeled afternoon. TS can then count how many pieces are left. TSW then be given a word problem to solve. TTW circulate to help with problems and check for understanding. The class will then solve that word problem together.

Student Product/Work:
TSW be given word problems to solve independently using Kidspiration.

Robert wants to practice goal kicks for soccer. He decides to have 12 kicks before going home from the park. He takes 5 kicks before taking a break to get a drink of water. He then takes another 4 kicks. How many more kicks does he need to make before he goes home?

Cindy has 15 stickers. She uses 6 stickers. She buys 5 more stickers. How many stickers does Cindy have now?

Brian has 14 pencils. He gives 5 pencils to a friend. He buys 3 more pencils. How many pencils does Brian have now?

Karen has 8 markers. Her mother gives her 4 more markers. Karen loses 3 markers. How many markers does she have now?

Assessment/Rubric:
The students will be assessed informally as they work and the teacher observes them using Kidspiration. The students will be assessed formally through their answers to the word problems.

Enrichment/Reteaching:
For enrichment students can create their own multi-step problems for a friend to share. Reteaching will be done as I circulate while students work on problems.
