Sorting Shapes

Grouping shapes by their properties

We can sort shapes into groups — by sides, by flat or solid, by rolling!
Flat (2D)
circle, square, triangle
Solid (3D)
cube, sphere, cone
We can sort shapes in many ways: flat vs solid, by number of sides, or which ones roll! Sorting helps us notice what shapes have in common. There is no single right way — it depends on your rule!
