## What is the making 10 strategy?

In 1st grade, as students begin learning their basic addition facts, they apply that knowledge in a **strategy** known as “make a **ten**” to help make sense of facts that might otherwise be hard to memorize, such as 8 + 4 or 9 + 5. To use the **strategy**, students decompose one of the addends to make a **ten** from the other.

## How many ways can you make 10?

There are 11 ways to **make ten**.

## What are counting strategies?

**Counting** On is a beginning mental math **strategy** for addition. **Counting** on means that you start with the biggest number and then **count** up from there. For example, to add 5+3, start with the “5” and then **count** up, “6, 7, 8.” This is to discourage students from **counting** like this: “1, 2, 3, 4, 5…..

## How do you teach a bridging 10?

Teachers will most likely **teach** the **bridging through 10** method by giving a demonstration on the board, and then by giving the children a worksheet with number lines already drawn for them on which to work out their sums.

## What happens every time you add 10 to a number?

The ones digit remains the same when **you add ten**. The tens digit increases by 1 **every time you add ten**.

## How do you explain 10 more and 10 less?

**Explain** that because the tens digit only changes by 1, we can find **10 more** or **10 less** by mentally adding or subtracting 1 to the number of tens. I model this by selecting a number and asking students to determine what number is **10 more** and what number is **10 less**.

## How do you find 10 more than any number?

To **find 10 more than** a **number**, add 1 to the digit at the tens place. To **find 10** less **than** a **number**, subtract 1 from the digit at the tens place. For example: Let’s **find 10** less **than** the **number** 47.

## How many ways can you make 8?

Note: 8 items have a total of **40,320** different combinations.

## What are the number bonds to 10?

What are **number bonds to 10**? **Number bonds to 10** are pairs of **numbers** that, when added together, give the **number 10**. They can also be called ‘**number** pairs’ or ‘**number** partners’. Examples are 1 & 9, 7 & 3 and 5 & 5.
