Halloween Activity for Toddlers – Make a Shape Sorter

A cardboard box, a few paint sticks and a handful of wooden blocks turn into a jack-o-lantern shape sorter your toddler will come back to all month. It teaches shapes and fine motor control, and it costs nothing.

Jump straight to the steps

Toddler posting a wooden block into a cardboard jack-o-lantern shape sorter taped to the wall — Four pumpkin faces stacked vertically so little hands can reach every one.

This is where crafting, playing and learning collide with a pumpkin twist. It builds fine motor skills and shape recognition, which is an early math skill, but the part I love is that you can give every pumpkin a different face.

That makes it a conversation about feelings as much as shapes. Name each emotion as you go. If that is the bit your kid latches onto, our Easy DIY Feelings Cup goes further with it.

What you need

How to make a pumpkin shape sorter

Cut pumpkin shapes out of flat cardboard.
Let the kids decorate them. We used orange and green paint sticks for the body and stem.
Once dry, pencil in eyes, a nose and a mouth on each one. Make every face different so you can talk about emotions.
Glue the pumpkins onto the box.
Cut out the eyes and mouths with a craft knife, going through both layers of cardboard so blocks can drop inside.
Tape it to the wall for a vertical setup, and it is ready to play.

Before you start

The craft knife step is an adult job, and small blocks are a choking hazard for children under three. Stay with them while they play.

Tips that actually make a difference

Match the number of pumpkins to your box. We had an odd tall box so we stacked several; a small box needs just one.
Leave an opening at the bottom so the blocks fall out. Mine love the clatter onto a metal tray. If you would rather they stayed in, leave a gap you can reach into instead.
Cover the pumpkins with clear packing tape before cutting. The cardboard edges tear once blocks start getting wedged in.
Start with two holes that look obviously different, then add the trickier shapes once they have the idea.

Six numbered step photos showing how to make a pumpkin shape sorter: a cardboard box and cut circles, a child painting the circles orange, gluing the pumpkins onto the box, cutting jack-o-lantern shape holes with a craft knife, and toddlers posting wooden blocks through the faces — The whole build – and give every pumpkin a different face so it doubles as a feelings activity.

Make it easier or harder

Just turned one

One pumpkin, one big round hole, large blocks only.

Two to three

Three or four shapes. Name the shape as they post it.

Preschool

Let them cut and trace. Add a color rule: only red blocks in the angry pumpkin.

No blocks

Bottle caps, pom poms or cut-up cardboard circles work fine.

Questions we get asked

What age is this Halloween activity best for?

Roughly 12 months to 3 years. Younger toddlers do well with one or two large holes, and by about two and a half most can manage four different shapes. Older preschoolers can help paint the pumpkins and draw the faces.

How long does it take to make?

About 20 minutes of actual work, plus drying time for the paint. Make it after bedtime and it is waiting for them in the morning.

What if my toddler posts everything through the biggest hole?

That is completely normal and still worth doing. Trial and error is the skill. Start with two holes that look obviously different, then add the trickier shapes once they have the idea.

How do I stop it falling apart?

Cover the painted pumpkins with clear packing tape before you cut the holes. It keeps the cardboard edges from tearing when a block gets wedged in, which it will.

Can I make it without a cardboard box?

Yes. A shoebox works, so does a plastic tub with holes cut in the lid, or a large sheet of cardboard taped flat to the wall if you are short on boxes.

Is it safe for a one year old?

With supervision. Use blocks too large to swallow, and keep the craft knife well away during the build. Never leave a toddler alone with small pieces.
