Lesson 16 Objective: Apply knowledge of area to determine areas of rooms in a given floor plan. Suggested Lesson Structure Practice (15 minutes) Development (35 minutes) Student Debrief (10 minutes) Total Time (60 minutes) Fluency Practice (15 minutes) Group Counting 3.OA.1 (3 minutes) Multiply by 9 3.OA.7 (7 minutes) Find the Area 3.MD.7 (5 minutes) Group Counting (3 minutes) Note: Group counting reviews interpreting multiplication as repeated addition. Instruct students to count forward and backward, occasionally changing the direction of the count. Sixes to 60 Sevens to 70 Eights to 80 Multiply by 9 (7 minutes) Materials: (S) Multiply by 9 (6–10) Pattern Sheet Note: This activity builds fluency with multiplication facts using units of 9. It works toward students knowing all products of two one-digit numbers from memory. See Lesson 2 for the directions for administration of a Multiply-By Pattern Sheet. T: (Write 6 × 9 = .) Let’s skip-count up by nine to solve. (Count with fingers to 6 as students count.) S: 9, 18, 27, 36, 45, 54. T: Let’s skip-count down to find the answer, too. Start at 90. (Count down with fingers as students count.) S: 90, 81, 72, 63, 54.
