# Ch 21: 4th Grade Math: Perimeter, Area & Volume

### About This Chapter

## 4th Grade Math: Perimeter, Area & Volume - Chapter Summary

If your 4th grade student is having a hard time keeping track of all the formulas used to calculate perimeter, area and volume, use the lessons in this chapter to help him or her sort them out. Fun video illustrations can give students a firm grasp of the methods for measuring the perimeter and area of basic shapes, like triangles and rectangles. The self-checking quizzes and transcripts could also come in handy when they're ready to tackle more complex formulas for the surface area and volume of cones, cylinders, pyramids and other 3-D shapes.
