Problem Solving

Solve simple shape stories by naming shapes and counting them.

Shape word problems

These little stories are about shapes. Look at the sides, corners, and how many shapes there are.

Key idea

Four steps: 1) read, 2) think about the shape, 3) answer or count, 4) check.

A worked story

Worked example

Sara draws a shape with 4 equal sides. What is it? A shape with 4 equal sides is a square.

Remember

  • Count sides to name a flat shape.
  • Round shapes roll; a cube does not.
  • "Altogether" means add the shapes.
