7. Application Problem 5 Minutes For Jordan to get to his grandparents’ house, he has to travel through Albany and Plattsburgh. From Jordan’s house to Albany is 189 miles. From Albany to Plattsburgh is 161 miles. If the total distance of the trip is 508 miles, how far from Plattsburgh do Jordan’s grandparents live? 189 508 161M Lesson 19

8. Concept Development 30 Minutes We will by writing problems today. Our strategy to solve word problems is: 1.I will display a tape diagram and give you the context. 2.Calculate to solve and write a statement. 3.Assess the solution for reasonableness. Lesson 19

9. Concept Development cont. 33 Minutes As you think about the problems, you need to ask yourself: What story makes sense with the diagram? What question will I ask in my word problem? Lesson 19

10. Problem 1 Create and solve a simple two-step word problem from the tape diagram below. Context: People at a football game. 1. Make up the problem. 2. Calculate to solve and write a statement. 3. Assess the solution for reasonableness. Step 1 Work SpaceStep 2 Work SpaceStep 3 Work Space What story makes sense? Lesson 19

11. Problem 2 Create and solve a two-step addition word problem from the tape diagram below. Context: Cost of two houses. 1. Model the problem. 2. Calculate to solve and write a statement. 3. Assess the solution for reasonableness. Step 1 Work SpaceStep 2 Work SpaceStep 3 Work Space Lesson 19

12. Problem 3 Create and solve a three-step word problem involving addition and subtraction from the tape diagram below. Context: Weight in kilograms of three different whales 1. Model the problem.2. Calculate to solve and write a statement. 3. Assess the solution for reasonableness. Step 1 Work SpaceStep 2 Work SpaceStep 3 Work Space Lesson 19

13. Problem 4 Students use equations to model and solve multi-step word problems. 5,233 + 3,094 + k = 12,946 Create a contextWrite a statement about the total and a question about the unknown. Tell the rest of the information. Draw a tape diagram that models this equation. Compare with your partner. Create a word problem that uses the numbers from the equation. Remember to first create a context, write a statement about the total and a question about the unknown. Then you can tell the rest of the information. K 12,946 5,2333,094 Note to teacher: The problem 4 in the module is not the same problem 4 as is on the Problem set. I used the one in the module thinking that our students could do Problem 4 with us then Problem 4 on the Problem Set work sheet independently. : ) Lesson 19

14. Problem Set (To be completed during the Concept Development portion of the lesson) These numbers are different than in the module.
