Parents Need to Know

Parents need to know that A Maths Dictionary for Kids is a dictionary and chart website for grade school to entry-level high school students that helps explain terms and concepts with words and visuals. As long as kids can read -- or have the content read to them -- they will find some helpful tips, from the basics of rounding numbers and math operations to fractions, ratios, and statistics. There is some interactivity here (move this shape here, insert a number there) but for the most part it's not as flashy as many of the popular sites geared for kids. Still, the printable charts are colorful and present concepts in alternative ways. Since this site is Australian-based, some of the vocabulary and spelling may be unfamiliar to non-Australian kids. A Maths Dictionary for Kids can be a helpful resource for kids seeking a better understanding of math terms and concepts.

What kids can learn

Engagement, Approach, Support


This is a jam-packed, multi-topic site for math help. Kids from grade school to early high school will find useful definitions, interactive explanations and colorful, creative charts.

Learning Approach

As kids look through the terms and concepts and choose the ones they want to know more about, they're directed to a definition, interactive exercise, and perhaps a chart to help them learn the term or concept in different ways. 


Kids must be able to read or have the content read to them to find the site helpful. Some of the vocabulary and spelling may be unfamiliar to non-Australian kids.

What kids can learn

Kids can learn many different math skills including, but not limited to: operations, numbers, fractions, decimals, ratios, time, measurement, geometry, and beginning algebra by using definitions, interactive activities, and charts. For example, to learn about rounding numbers, kids enter a number that gets rounded to the tens and hundreds places, and also shows them how that looks on a chart. Kids can also learn critical thinking skills and how to further their own academic progress using quality online, interactive resources such as "A Maths Dictionary for Kids." This is a jam-packed, multi-topic site for supplemental math help.

Is it any good?


A Maths Dictionary for Kids can be very useful for kids, parents, and teachers to help supplement math lessons with definitions and charts on a wide variety of math concepts. Kids from grade school to early high school (as well as parents who have forgotten certain math concepts that kids bring home in their homework) will find useful definitions and interactive explanations, as well as colorful, creative charts to help clarify or reinforce school lessons. Even younger kids who can't yet read may be able to learn basic math concepts here with a parent's help. The charts on this no-ad (at the time of this review) site can also be printed for educational-only, non-commercial use. An excellent math (or maths, depending upon where you live) resource.

My school actually used this for my high math class. It's a great resource, and a fun interactive dictionary.
