About this worksheet

What shape is the slice?. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

I can name the shape a flat cut leaves: a rectangle (or square) when the cut is parallel to a face, a triangle when it slices off a corner or passes through a pyramid's top point.
I can say a flat cut leaves one side for each face it crosses, and use that to name the shape (3 faces, a triangle; 5 faces, a pentagon).
I can tell that slices of a box all match its base, but slices of a pyramid get smaller toward the top, and I can find the area and distance around a slice.

Standard: 7.G.A.3

Words to know

slice (cross-section): The flat shape you see where a flat cut goes through a solid.

rectangular prism: A box with 6 rectangle faces. A cube is a box with all edges equal.

rectangular pyramid: A solid with a rectangle base and 4 triangle faces that meet at a top point.

face: One flat side of a solid.

parallel: Always the same distance apart, like the top and bottom of a box.

top point: The corner where a pyramid's triangle faces meet. It sits above the middle of the base.

trapezoid: A four-sided shape with one pair of parallel sides.

Common mistakes

Your child named the shape of one of the solid's faces instead of the shape the cut leaves. Try it with a block of play dough and a ruler: cut it, then look at the flat cut surface, not the outside faces.

Your child pictured the diagonal line on top and named a triangle.

Your child thought a straight-down cut gives a rectangle.

What to say

Ask: the cut goes straight down the whole box, so what do the sides of the slice look like?

Ask: the sides of a pyramid lean inward, so does the slice have leaning sides too?
