Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 7
- Here are 24 cubes in a box that's 4 by 3 by 2.
- Here are the same 24 cubes, packed differently. This box is 6 by 2 by 2. It looks longer, but the volume hasn't changed.
- To find every box, look for three numbers that multiply to 24. For example, 1 by 1 by 24 is one long line of cubes, and 2 by 3 by 4 is a tidy block.
- If you know the volume and one layer, you can find the height. 24 cubes in layers of 6 means 4 layers.
