Kavi Unfolds the Boxes 📦
Kavi snips open a cereal box and lays it flat on the branch. "Look!" hoots Kavi. "A 3D solid is made of flat faces. When you unfold a solid so all its faces lie flat, you get its net. Count the faces and check their shapes, and you can tell exactly which net folds back up into which solid!"

What your child will learn
1A net is a solid unfolded flatEvery 3D solid is made of flat faces. A net is what you get when you unfold the solid so all the faces lie flat — fold it back up along the edges and you get the solid again. Tap each solid to see its faces and its net.
2Which solid does each net fold into?
3Count the faces, then check their shapesTo match a solid to its net, use two checks together. Tap each card to see how.

A peek inside
Kavi sees a net made of 6 equal squares. Which solid does it fold into?
6 faces, and every face is a square → a cube
Try this at home: How many faces does a cube have, and what shape are they?
