Website Reviews: CoBELS - Math And Science Site For Kids

You need to know that CoBELS is a math and science site for third through eighth graders. The developers are based in India so with the favorable rupee-to-U.S.-dollar exchange rate, the cost of the site is very reasonable. Terms such as Mensuration, though common in India, may be confusing to kids. But once they get going in the games they will realize it simply means measuring geometric shapes. Each activity or game targets a specific learning objective. Personal information is collected, but it's hard to tell how it's being used. Concerned parents should check out the site's full privacy policy.

Some games are definitely more fun than others. But the math or science itself is usually interesting enough to keep kids' attention.


CoBELS provides a context so there's a reason to do the math or science. Kids see they can make up rules or equations to make their work faster.


Narrators coach kids through each activity. But they don't give targeted feedback based on the types of mistakes kids are making.

COBELS lets kids construct their own math and science ideas by playing games. They can learn about math topics such as fractions and decimals, as well as science topics such as plants and animals. Games, such as Polygon Perimeter, begin with a short introduction and a few examples. Kids build on that knowledge as they play the game and figure out their own equations for different polygons. Immediate feedback and game scores help kids know how they are progressing.

This math and science site is powerful since students actually use these subjects to make sense of the world, creating their own equations or hypotheses to solve realistic problems. For example, Sheep Barn is a game that brings a story problem to life. Students have to figure out how to keep the sheep from escaping by determining the number of missing portions of fence and the amount of wood needed. They anxiously collect data, fill out a table, and drag in fence parts all while the sheep keep running away. A narrator encourages kids to look for patterns in their data so they can work more quickly.

Plant Power is a really fun game where kids have to quickly scoop up pollutants without grabbing the ingredients plants do need for photosynthesis. The introduction provides accurate science information, but the game doesn't really help kids understand why plants need those ingredients. Each of the games has its own strengths and weaknesses, but throughout CoBELS, kids are encouraged to think critically and to use science and math.
