Module 3 lesson 7
- 1. Multiplication and Division Using Units of 6 and 7 Module 3: Lesson 7 Objective: Interpret the unknown in multiplication and division to model and solve problems using units of 6 and 7.
- 2. Multiply by 7 (7 minutes) 7 x 5 = Let’s skip count by sevens to find the answer. I will raise a finger for each seven. 7 x 3 = Let’s skip count up by sevens again. Let’s see how we can skip-count down to find the answer too. Start at 35 with 5 fingers, 1 for each seven. Repeat the process for 7 x 4
- 3. Multiply by 7 (7 minutes) Let’s practice multiplying by 7. Be sure to work left to right across the page
- 4. Group Counting (4 minutes) Sixes to 60 Eights to 80 Nines to 90
- 5. Decompose the Multiplication Sentence (4 minutes) 6 x 6 = (5 + ) x 6 Complete this equation ( x 6) + ( x 6) Complete this equation Write an addition equation. Below it write your answer. Continue with the following suggested sequence: 8 x 6, 7 x 6, 9 x 6
- 6. Concept Development (10 minutes) Thad sees 7 beetles when he weeds his garden. Each beetle has 6 legs. How many legs are there on all 7 beetles? Talk to a partner, what kind of picture can we draw to model this problem? Draw and label a tape diagram to model this problem. Use the letter b, for the beetles’ legs, to represent the unknown.
- 7. What does the letter on your tape diagram represent? Next to your tape diagram, write an equation for the problem and solve it. Talk to a partner, what strategy did you use to find b? Write a sentence to answer the problem and then read your sentence to a partner. Repeat the process with 48 ÷ 6
- 8. Application Problem (25 minutes) During this time, students work together in groups to complete the second page of the Problem Set.
- 9. Problem Set (10 minutes) Student Debrief (10 minutes) Exit Ticket (3 minutes)
- 10. Homework 3-3 Lesson 7 Homework Is Due Tomorrow!
