Let's Sort Shapes! (For 6‑year‑olds)

We are going to learn how to sort shapes — that means putting similar shapes together. This is like making little groups of friends that look the same.

Shapes to know

  • Circle – round like a ball or a plate.
  • Square – four equal sides and four corners (like a window).
  • Rectangle – four sides, opposite sides equal (like a door).
  • Triangle – three sides and three corners (like a roof).
  • Other shapes – pentagon, hexagon, star (you can add these when ready).

What you need

  • Some paper shapes, toys, picture cards, or cut-outs (about 12–20 pieces).
  • Four small trays, baskets or drawn circles on a mat for each shape group.
  • Marker and paper to draw or label groups.

Step-by-step sorting activity

  1. Spread all the shapes out so you can see them.
  2. Pick one shape to start (for example, a circle). Say its name: "This is a circle."
  3. Look for every other circle and put them together in one basket or on one spot.
  4. Do the same with the next shape: find all squares and put them in another basket.
  5. Keep going until you have a basket for each kind of shape.
  6. Count how many shapes are in each group. Which group has the most? Which has the least?

Ways to sort (different ideas)

  • By shape: circles together, squares together, etc.
  • By size: big shapes in one pile, small shapes in another.
  • By color: all red shapes together, then blue, and so on.
  • By number of sides: 3 sides (triangles), 4 sides (squares/rectangles), 5 sides, etc.

Games to make it fun

  • Shape Hunt: Ask the child to find a shape in the room ("Find a rectangle!").
  • Race: Turn sorting into a timed game — who can sort all shapes first?
  • Guessing Game: Hold a shape behind your back and give clues ("I have 3 sides").

Questions to ask while sorting

  • How many sides does this shape have?
  • Is this shape round or pointy?
  • Which group has the most shapes?
  • Can you make a pattern with two shapes? (e.g., circle, square, circle, square)

Extension activities

  • Draw a picture using only one kind of shape (a house with a square and triangle roof).
  • Make a shape collage: glue sorted shapes onto paper and label them.
  • Introduce new shapes (pentagon, hexagon) and ask the child to decide where they belong.

How to know they understand

If the child can correctly name most shapes, sort unfamiliar sets of mixed shapes, and explain how they grouped them (by sides, size, or color), they understand shape sorting well.

Have fun! Keep activities short and playful — 10–15 minutes is great for a 6‑year‑old.
