Skill: Recall multiplication facts for 3

To recall a multiplication fact for $3$, think of equal groups of 3 or count by 3s:

$$3,\ 6,\ 9,\ 12,\ 15,\ 18,\ 21,\ 24,\ 27,\ 30$$

These are the products of $(3 \times 1)$ through $(3 \times 10)$.

Example: Find $(3 \times 7)$

1. Think of $7$ equal groups with $3$ in each group.

2. Count by 3 seven times:

$$3,\ 6,\ 9,\ 12,\ 15,\ 18,\ 21$$

3. The seventh number is $(21)$, so:

$$3 \times 7 = 21$$

You can also show this with repeated addition:

$$3+3+3+3+3+3+3=21$$

The reversed multiplication fact has the same product:

$$7 \times 3=21$$

So, when you see a multiplication fact with $3$, count by 3s or picture equal groups of 3.
