Grades K-8, with parental supervision

This ad-supported website offers free lessons, games, and worksheets to learn arithmetic basics as well as some advanced math (for grades K-8) in a non-conventional format.

The relaxed style of presentation sprinkles humor throughout the explanations of math concepts. The use of the latest multi-media technology to illustrate the concepts through interactive games and activities really helps reinforce the learning.

When you get to the site you’ll see an icon menu. Before you explore it, scroll down the page and read the brief introduction designed to help you navigate the site. Then, from the icon menu simply pick a topic to get started, including:

- Shapes & Colors
- Counting Numbers
- Add Numbers
- Subtract Numbers
- Multiply Numbers
- Divide Numbers
- Operations Order
- Dates & Times
- And many more

Click on any one and a new page opens with a “lesson” – an explanation and illustration of the concept. In most cases, you’ll find an online activity that students can do to reinforce the learning.

And – GET FREE ADDITION & SUBTRACTION WORKBOOKS!

Below the icon menu, you’ll see the words “Math Workbooks.” Click on it and a new page will open with free “Addition” Workbooks. (Look in the upper right corner of the page to find a link to the “Subtraction” workbooks.) The workbooks are in pdf format so you can save them to your computer and print them out to do offline.
