Hi all! As far as I'm concerned, shape is the basis of geometry, every child should be able to distinguish 3D shapes, but not everyone can do it right away. If your child has difficulty with this, I can offer you 3d shape worksheet kindergarten from Brighterly online school. This online school will help your child with any topic in which they have difficulties, and they find an individual approach to each student.
I think I helped you with your question.
