Step 1: Fill in the boxes. The boxes represent multiplication tables. Row 1 (2 times table): 2, 4, 6, 8, 10, 12, 14 Row 2 (5 times table): 5, 10, 15, 20, 25, 30, 35 Row 3 (10 times table): 10, 20, 30, 40, 50, 60, 70 Step 2: Write the repeated additions as multiplication. 3 + 3 + 3 + 3 = 4 × 3 5 + 5 + 5 = 3 × 5 Step 3: Write the multiplications as repeated addition. 3 × 4 = 3 + 3 + 3 + 3 4 × 6 = 4 + 4 + 4 + 4 + 4 + 4 1 × 7 = 1 + 1 + 1 + 1 + 1 + 1 + 1 4 × 5 = 4 + 4 + 4 + 4 + 4 Step 4: Fill in the blanks. 4 × 2 = 8 3 × 8 = 24 4 × 7 = 28 2 × 9 = 18 2 × 7 = 14 5 × 6 = 30 Step 5: Add by using multiplication table. 2 + 2 + 2 + 2 + 2 = 5 × 2 = 10 4 + 4 + 4 + 4 + 4 + 4 = 6 × 4 = 24 3 + 3 + 3 + 3 = 4 × 3 = 12 5 + 5 + 5 = 3 × 5 = 15 Step 6: Solve the word problem. A fan has three blades. A room has four fans. To find the total number of fan-blades, multiply the number of blades per fan by the number of fans. 3 × 4 = 12
