Sharpen Math Skills with Online Games and more

May 17th, 2021



Grades 1-8, with parental supervision is an ad-supported website that offers FREE math games to learn and practice basic math skills.

Description: is an ad-supported website that offers FREE math games to learn and practice basic math skills in the following areas:

  • Addition
  • Subtraction
  • Multiplication
  • Division
  • Fractions
  • Integers
  • Algebra

When you get to the site, you’ll see some featured games. To sort by math strand and grade range, scroll to the menu at the bottom of the page.

Notice that the games can be sorted by game style as well – such as games that require the player to escape, shop, build, race, etc.

IMPORTANT: Every game is free to play but is accompanied by a randomly generated advertisement, usually delivered as a video clip. Some of the ad content is geared for adults, not kids. As always, parents should preview the website and supervise all Internet access.

You’ll also find links to some animated math “movies” and math tutorials (on a YouTube channel with random ads) that provide instruction in Whole Numbers, Decimals, Fractions, Ratio and Proportion, Percent, Integers, Order of Operations, Algebra, and Geometry designed for grades 3-6. To find the movies and tutorials look at the top of the home page for links. The videos are meant to be entertaining but may seem silly to more mature kids.

IS All About Math


Grades 5 and up, with parental supervision


This website provides short instructional math videos that can be used to supplement math studies. The videos consist of a narrated lecture and animations that illustrate the concept being discussed. The videos are enabled for iPhone, iPod, and iPad devices for portable, on-the-go learning.

When you get to the website you’ll see a menu of math videos that include topics such as: 

  • Triangular Numbers (Parts I, II & III) – Elementary explanation of triangular numbers, general formula for the sum of an arithmetic progression, and a solution to the Recursive equation.
  • Mathematical Induction (Parts I, II, & III) – Explains the Method of Mathematical Induction. Discussion of Francesco Maurolico, Pascal and John Wallis, plus Fermat’s Method of infinite descent, etc.
  • Weaving Numbers – Explanation of Vedic multiplication or weaving multiplication. Includes Fibonacci’s sieve or lattice multiplication, and more.
  • Dimension 2 – Explains how two numbers can describe the position of a point on a sphere, and how one can draw a picture of the Earth on a piece of paper.
  • The Fourth Dimension – Mathematician Ludwig Schläfli discusses objects in the fourth dimension.
  • Complex Numbers – Mathematician Adrien Douady explains the square root of negative numbers in simple terms.
  • Pi – An explanation and illustration of the most famous mathematical constant.

The narrator on some of the videos speaks in a monotone voice with an accent, so we found it necessary to really pay attention to hear and understand the lectures. Fortunately, the animated illustrations help the viewer to maintain focus.

We couldn’t find “about” information on the site, so it’s not clear who is providing the info or why. Currently, there are no advertisements on the site, and all of the videos can be accessed for free, without registration. 

This is a helpful resource for supplementing the study of various math concepts.
