Here's a hands-on activity you can do with your fourth-grader to practice measurement and directly apply the concept of area.

This fun activity encourages your child to develop their skills in not only taking measurements, but also in working with the measurements themselves.

Introduce your fourth or fifth grader to volume by having him build rectangular prisms, and then count each sugar cube to check his volume calculations.

This game is a great way to help your child remember the names of shapes. Give it a go and before you know it, your kid will have all her shapes down pat.

In this fun science fair project, make two different scale models of our solar system using Astronomical Units and planets' relative size!
