Classifying Numbers: Real and Whole

Classifying Numbers: Real and Whole is a concept from the grade 9 math curriculum in Ontario, Canada. This concept helps us to understand how numbers are related to each other and how to categorize them. To classify numbers, we compare them by determining if a number is real or whole.

A real number is a number that can be expressed as a fraction, decimal, or percentage, or as an irrational number. Examples of real numbers include 43/100, 0.43, 43%, and √2.

A whole number is a number that cannot be expressed as a fraction. Examples of whole numbers include 0, 1, 2, 3, 4, etc.

Here is an example of how you can determine if a number is real or whole:

Example 1:

Question: Is 2.5 a real or a whole number?

Answer: 2.5 is a real number because it is a decimal number, which can be expressed as a fraction or percent.

Advice on Helping a 14 Year Old with Dyslexia to Understand Classifying Numbers: Real and Whole

This concept can be challenging for someone with Dyslexia to understand. Some specific things that a 14 year old who has Dyslexia may find difficult include:

Example 1: Memorizing Number Forms

Memorizing which form of numbers are considered real numbers and which form of numbers are considered whole numbers can be difficult for a 14 year old with dyslexia. To help them, teach them mnemonic devices that they can use to remember which type of numbers go with which category. For example, you can use the acronym RWFT (Real Wholes Fraction Ten) to easily remember that fractions, whole numbers, and decimals are all real numbers and that a ten is a whole number.

Example 2: Connecting Equations with Symbols and Numerals

A 14 year old with dyslexia may have difficulty connecting equations with the symbols and numerals used to represent them. To help them, you can use physical objects to create equations in order to easily show the connection between the equation and its representation. For example, you can assign a certain numerals to a particular number of objects to visually represent equations.

Example 3: Comparing Numbers

Comparing two numbers to see if they are real or whole can be difficult for a 14 year old with dyslexia. To help them, you can use visual aids. For example, you can use a Venn diagram to show how two numbers can be related to each other. You can also create charts that compare the different forms of numbers and explain what each type of number looks like.

At the end of the day, the most important thing is to be understanding and patient with a 14 year old with dyslexia. Classifying Numbers: Real and Whole can be a difficult concept to understand, so it is important to provide support, resources, and guidance in order to ensure that the student is able to properly understand the concept.

Classifying Numbers: Real and Whole
