HOME CONNECTION Your child learned to
recognize solid figures
and classify them by
their attributes.
Put an X on the solid figures that have edges.
Underline the solid figures that have vertices.
Circle the solid figure that does not have a flat surface.
sphere
triangular
prism
cylinder
cone
cube
HOME ACTIVITY Take
your child on a hunt for solid
figures in your home or
neighborhood. Ask your child
to describe each solid figure
he or she sees.
