Multiplication facts answers: exercises 1 to 10

Exercise 1 – Skip count by 3

Count by 3: 3, 6, 9, 12, 15, 18. The hidden numbers are 12, 15, and 18. Six hops of 3 land on 18.

The completed number line.

\(3 \times 6 = 18\)

Exercise 2 – Fives

Count by 5: 5, 10, 15, 20, 25, 30, 35.
\(5 \times 7 = 35\)

Exercise 3 – Doubles

Double 9: \(9 + 9 = 18\).
\(2 \times 9 = 18\)

Exercise 4 – Tens

Each group is 10, so 8 groups make 80.
\(8 \times 10 = 80\)

Exercise 5 – Nines

The tens digit is \(5 – 1 = 4\). The ones digit makes the digits add to 9, so it is 5. Check: \(4 + 5 = 9\).
\(9 \times 5 = 45\)

Exercise 6 – Threes

Double 7 is 14. Add one more 7: \(14 + 7 = 21\).
\(3 \times 7 = 21\)

Exercise 7 – Square fact

Six groups of 6 make 36.
\(6 \times 6 = 36\)

Exercise 8 – Fours

Double 7: \(7 + 7 = 14\). Double 14: \(14 + 14 = 28\).
\(4 \times 7 = 28\)

Exercise 9 – Eights

Double 8 is 16, double 16 is 32, and double 32 is 64.
\(8 \times 8 = 64\)

Exercise 10 – Share equally

Think: 4 times what number is 24? \(4 \times 6 = 24\).

4 groups of 6 make 24.

\(24 \div 4 = 6\)

Exercises 11 and up

Exercise 11 – Missing factor

Think \(48 \div 6\). \(6 \times 8 = 48\).
\(n = 8\)

Exercise 12 – Fact family

The top number is the product: \(3 \times 9 = 27\).

The completed triangle.

The four facts are \(3 \times 9 = 27\), \(9 \times 3 = 27\), \(27 \div 3 = 9\), and \(27 \div 9 = 3\).

Top number: 27

Exercise 13 – Divide by 9

Think: 9 times what number is 63? \(9 \times 7 = 63\).
\(63 \div 9 = 7\)

Exercise 14 – Use a known fact

\(6 \times 8\) is one more group of 8 than \(5 \times 8\). \(40 + 8 = 48\).
\(6 \times 8 = 48\)

Exercise 15 – Little League teams

\(6 \times 8 = 48\). Use \(5 \times 8 = 40\) and add 8 more.
48 players

Exercise 16 – Sticker book

\(54 \div 6 = 9\) because \(6 \times 9 = 54\).

6 pages with 9 stickers each.

9 stickers

Exercise 17 – Snack bags

Nines trick: the tens digit is \(7 – 1 = 6\) and the digits add to 9, so the ones digit is 3. Check \(7 \times 9 = 63\).
63 crackers

Exercise 18 – Peach baskets

Think \(8 \times n = 72\). \(8 \times 9 = 72\), so \(72 \div 8 = 9\).
9 baskets

Exercise 19 – Flower rows

\(7 \times 6 = 42\). A division fact is \(42 \div 7 = 6\) or \(42 \div 6 = 7\).
42 flowers

Exercise 20 – Paper cups

Find the missing factor: \(7 \times 8 = 56\), so there are 8 rows.

Fact family triangle for 7, 8, and 56.

The fact family is \(8 \times 7 = 56\), \(7 \times 8 = 56\), \(56 \div 8 = 7\), and \(56 \div 7 = 8\).

8 rows

Key facts behind this multiplication facts answers

Key facts

A fact family uses three numbers: \(6, 7, and 42\) make \(6 \times 7 = 42\), \(7 \times 6 = 42\), \(42 \div 6 = 7\), and \(42 \div 7 = 6\).
Division is finding a missing factor: 42 ÷ 7 asks 7 times what number is 42.
Products of 5 end in 0 or 5, and the digits of a product of 9 add to 9.
Doubles help with 2s and 4s. Add one more group to move from a known fact to the next one.
Fluency means knowing the facts from memory, quickly and correctly.
