Skill: Recall division facts for 2, 5, and 10

Division asks: How many equal groups are there? For facts with divisors $2$, $5$, and $(10)$, use a multiplication fact you know.

Example: Find $(40 \div 5)$.

1. Think of $(40)$ objects split into equal groups of $5$.
2. Ask: “How many groups of $5$ make $(40)$?”
3. Use the related multiplication fact:

$$5 \times 8=40$$

4. Therefore:

$$40 \div 5=8$$

So, $(40)$ can be divided into 8 equal groups of 5.

Helpful patterns:

• Numbers divided by $2$ are even.
• Multiples of $5$ end in $0$ or $5$.
• Multiples of $(10)$ end in $0$.
