One of the best ways to learn and understand volume is visually, and because of that it can sometimes be a hard subject to teach. If your class is struggling, let your students check out and explore ‘Turn the Volume On!’
If you don’t have a computer in class, you can try Melissa Blough’s strategy of using sugar cubes to help your students learn volume. Students can build rectangles using the sugar cubes. Once their rectangle is complete, the students can attempt to calculate the volume. To check their work, they can simply count the sugar cubes.
