# Dyslexia: Exponents with Integer Bases from the gr9 Math curriculum in Ontario

For Parent

## What is an Exponent with an Integer Base?

Exponents with integer bases is a mathematical concept that involves taking a number and multiplying it by itself multiple times. The exponent is the number of times it is multiplied by itself. For example, 2 to the 3rd power is written as 23 and can be solved by multiplying 2 by itself 3 times. This can be written as 2x2x2 or 8.

## How to Help Your 14 Year Old With Dyslexia Understand Exponents with Integer Bases

There are a few issues that your 14 year old with Dyslexia may run into while trying to understand Exponents with Integer Bases. First, they may have a hard time understanding the equation. To help, draw a visual representation of the equation using objects like blocks to make it easier to understand. Second, they may also have difficulty with memorizing terms. To help, break each term down to its simplest form and use visual memory techniques such as mnemonics. Third, they may struggle with keeping track of the multiplier numbers and the amount of times the number is multiplied by itself. To solve this issue, try using memory tricks such as mental imaging to reinforce multiply numbers and exponents.

## Examples for Helping Your 14 Year Old With Dyslexia Understand Exponents with Integer Bases

### 1. Use Visual Representations

For example, when solving an equation like 23 = 8, you can use visuals such as blocks to help. Take two blocks, stack them up, then stack the two original blocks onto that new stack. This matches the equation 2x2x2, which is equal to 8.

### 2. Break Terms Down Into Simpler Forms

If your 14 year old finds vocabulary like exponent and base confusing, help them by breaking these words down into their simplest forms. Explaining the exponent as ‘the number of times it is multiplied by itself’ and the base as ‘the original number before it’s multiplied’ may make it easier for them to understand.

### 3. Use Memory Tricks

To help your 14 year old remember the purpose of the exponent and the multiplier numbers for equations such as 23, use memory tricks such as mental imaging. For example, imagine that the number 2 is holding a flag with the number 3 written on it – this is a visual representation that the 2 is being multiplied by itself 3 times.

Equation Example: 23 = 8
