## Why do we use 10 frames?

Ten frames are an amazing tool used in kindergarten and first grade to help your children understand counting, place value (e.g. where the digit in a number is), adding, subtracting, and more. Young learners who have a solid understanding of this number, can relate that understanding to all different areas of math.

**What counts back strategy?**

Counting back is normally the first strategy that students use when they are learning to subtract. Counting back simply means starting with the minuend (the largest number) and counting back to figure out the difference. With counting up, students start with the subtrahend and count up to the minuend.

### What is the Add to subtract strategy?

The Add Up strategy involves adding up from the number being subtracted (subtrahend) to the whole (minuend). Start by selecting problems where the minuend and subtrahend are close together (e.g. 57 – 53 or 332 – 326) to build an understanding of subtraction as the distance between two numbers.

**How do you add and subtract fast in your head?**

How to add and subtract in your head

- To add 9 to another number, add 10 and then subtract 1: 36 + 9 = 36 + 10 – 1 = 45.
- To add 18 to another number, add 20 and then subtract 2: 48 + 18 = 48 + 20 – 2 = 66.
- To add 97 to another number, add 100 and then subtract 3: 439 + 97 = 439 + 100 – 3 = 536.

#### What is the 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.

**What does ten frames mean In addition and subtraction?**

One ten frame represents the tens and the other ten frame represents the ones. Addition and Subtraction – Ten frames are also great for teaching kids how to add and subtract.

## How does ten frame work as a manipulative?

Ten Frame is an online mathematical manipulative that helps students develop basic number sense through the composition and decomposition of numbers within 5, 10, 20 and beyond. Ten Frame helps students understand counting, addition and subtraction.

**How do you use make 10 to subtract?**

Using numbers carefully crafted to support the use of Make 10 to Subtract, students roll an equation. Working in the semi-concrete, students then draw their initial subtrahend on the ten frame. Then, students cross-out/subtract the second smaller subtrahend. Students then write the equations that match their ten frames.
