Multiplication Facts 0-10 — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Which product is greater: 6 × 8 or 7 × 7?
A) 6 × 8 because it equals 48
B) 7 × 7 because it equals 49
C) They are equal
D) 6 × 8 because it equals 54
6 × 8 equals 48 but 7 × 7 equals 49, so the square of 7 wins by exactly one — when factors are closer together, the product is larger.
2. What pattern do all products of 9 follow when you add the digits?
A) The digits always add to 10
B) The digits always add to 9
C) The digits always add to 18
D) There is no pattern
Try a few: 18 (1+8), 27 (2+7), 36 (3+6), 45 (4+5) — every product in the 9s table has digits that sum to 9, a neat way to check your work.
3. A rectangle is 8 units long and 6 units wide. What is its area?
A) 14 square units
B) 28 square units
C) 48 square units
D) 42 square units
Area of a rectangle is length times width, so 8 × 6 = 48 square units fill the inside.
4. Which two facts share the same product: 3 × 8 and ___?
A) 6 × 3 = 18
B) 4 × 6 = 24
C) 5 × 5 = 25
D) 2 × 9 = 18
Both 3 × 8 and 4 × 6 equal 24, because halving one factor while doubling the other keeps the product the same.
Part B: Fill in the Blank
Write the correct answer on each line.
1. 9 × 6 = 54, so 9 × 7 = 54 + 9 = 63.
Going from 9 × 6 to 9 × 7 means adding one more group of 9, and 54 + 9 = 63.
2. The product of 8 and 8 is 64.
Squaring 8 means 8 × 8, and that equals 64 — a common fact found on a checkerboard with 8 rows of 8 squares.
3. If you know 5 × 6 = 30, then 5 × 7 = 30 + 5 = 35.
Adding one more group of 5 to 5 × 6 turns it into 5 × 7, so the missing addend is 5 and the total grows from 30 to 35.
4. A square has sides of 9 units. Its area is 81 square units.
A square's area is side × side, so 9 × 9 = 81 square units cover the inside.
5. 10 × 10 = 100.
Ten groups of ten — like ten dimes — make 100, which is also written as 10 squared.
