2nd Grade Vertices Edges and Faces Worksheet: Which Solid Has the Most?

Hand a seven-year-old a cereal box and ask how many corners it has, and they will usually count only the ones they can see. Turning the box over is the lesson. This 2nd grade vertices edges and faces worksheet puts that counting into five short rows. Each row shows three figures, such as a cube, a ball, a pyramid, a cone, a cylinder, a long box or a hexagonal prism. A line above tells your child what to look for: the fewest faces, the most vertices, the most edges, the fewest edges or the most faces. They tick one figure per row. A second page gives the answer key.

Why the hidden side counts too

A drawing of a solid shows only part of it. The dotted lines stand for the edges at the back, the ones you would feel if you held the shape. Counting vertices, edges and faces forces a child to imagine that hidden part.

The three words are worth learning early. A face is a flat surface. An edge is where two faces meet. A vertex is a corner where edges meet. Many children mix up edges and vertices, so this page gives them practice on both.

The page also uses comparison words. So your child must count, then compare three numbers, then decide. For example, "the most vertices" means more than both of the others. Three counts, one choice.

At the table: the box and the pyramid

Start with the row that asks for the fewest faces. Let your child count the faces of the cube first, then talk about the ball. Ask, "Can you find a flat part on it?"

In the row about edges, the long box is the strong candidate. A child may count only the solid lines and forget the dotted ones. Instead of correcting, say, "Trace every line with your finger, dotted ones too." A light pencil tick on each edge helps.

The row asking for the fewest edges can surprise. The pyramid with a triangle base looks busy, yet it has few edges. Have your child count, write the number beside each figure, then compare. Writing the numbers makes the choice easy.

Counting corners around the house

Real objects make these words stick. Take a tissue box or a cereal box and count the faces together, turning it in your hands. Then put a small sticker on each corner and count the stickers. Also, run a finger along each edge of a dice or a sugar cube.

A quick game of Simon Says works well with solids. Say, "Simon says touch a vertex," then "Simon says slide along an edge." Let your child lead the next round.

When you compare two solid shapes, ask which has the most vertices and why. Finally, praise the counting: "You turned the box to find the hidden corners." That patience is the real skill.
