30. Problem-Solving Strategy: Solve a Simpler Problem 10-4 Five-Minute Check (over Lesson 10-3) Main Idea California Standards Example 1: Problem-Solving Strategy Lesson 4 Menu

31. Problem-Solving Strategy: Solve a Simpler Problem 10-4 • I will solve problems by working a simpler problem. Lesson 4 MI/Vocab

32. Problem-Solving Strategy: Solve a Simpler Problem 10-4 Standard 3MG1.3Find the perimeter of a polygon with integer sides. Standard 3MR1.2Determine when and how to break a problem into simpler parts. Lesson 4 Standard 1

33. Problem-Solving Strategy: Solve a Simpler Problem 10-4 Julianna is placing a border around a rectangular bulletin board. The perimeter of the bulletin board is 10 feet. One side measures 2 feet. What will be the length of the border for each side? Lesson 4 Ex1

34. Problem-Solving Strategy: Solve a Simpler Problem 10-4 Understand What facts do you know? • The bulletin board is rectangular with a perimeter of 10 feet. • The length of one side is 2 feet. What do you need to find? • The length of the border for each side. Lesson 4 Ex1

35. Problem-Solving Strategy: Solve a Simpler Problem 10-4 Plan Solve a simpler problem to find the length of the border for each side. Lesson 4 Ex1

36. Problem-Solving Strategy: Solve a Simpler Problem 10-4 total of 2 sides total of remaining sides perimeter 10 feet 4 feet 6 feet Solve Two sides are 2 feet long. 2 feet + 2 feet = 4 feet Find the total length of the other two sides. – = Lesson 4 Ex1

37. Problem-Solving Strategy: Solve a Simpler Problem 10-4 Solve The two unknown sides add up to 6 feet. Since both sides are the same length, divide by 2. 6 feet ÷ 2 feet = 3 feet Answer: So, two pieces of border should be 2 feet long, and the other two should be 3 feet long each. Lesson 4 Ex1

38. Problem-Solving Strategy: Solve a Simpler Problem 10-4 Check Look back at the problem. Add up all of the sides. 2 feet + 2 feet + 3 feet + 3 feet = 10 feet So, the answer is correct. Lesson 4 Ex1
