  2. Set out glue sticks, masking tape, stickers, and markers for decorating.
  3. Show your child the materials and say 'Let's build a robot! What shall we use for the body?'
  4. Help them choose a large box for the body and stick a smaller pot or box on top for the head using masking tape.
  5. Attach toilet roll tubes as arms and let your child decide where they go — wonky is wonderful.
  6. Offer stickers for eyes and markers for drawing a mouth, buttons, or dials on the body.
  7. Once the robot is built, give it a name together and make up a short story about what the robot can do.
  8. Display the finished robot on a shelf or windowsill where your child can admire their creation throughout the day.

Parent tip

Set out cereal boxes and glue stick before inviting your toddler in so the first minute feels smooth.

What success looks like

Messy hands and a child who doesn’t want to stop. The artwork doesn’t need to look like anything — the process is the point.

Junk modelling is the ultimate open-ended creative activity for toddlers: there is no right answer, no template, and no way to get it wrong. In this activity, your child transforms household recyclables into a robot character using glue, tape, and whatever decorations they fancy. The process of choosing materials, sticking them together, and deciding what their robot looks like exercises planning, spatial reasoning, and imaginative thinking all at once.

Why it helps

Junk modelling develops what early years educators call 'design thinking' — the ability to envision something that doesn't yet exist and work out how to make it real. This type of three-dimensional construction strengthens spatial reasoning and planning skills that are closely linked to later mathematical ability. The open-ended nature of the task also builds creative confidence because every choice the child makes is valid. The EYFS framework recognises that when children are free to create without adult direction, they develop the kind of original thinking that no worksheet can teach.

Variations

  • Build a junk model animal instead — a dog with a box body and tube legs, or a caterpillar from a chain of yoghurt pots.
  • Use foil to cover the robot for a shiny metallic look, adding a sensory texture element to the craft.
  • For younger toddlers, pre-tape the basic shape and let them focus entirely on the decorating stage.

Safety tips

  • Check all recyclables for sharp edges, staples, or residual food before offering them to your child.
  • Supervise glue and tape use closely — masking tape can be a tangling hazard if wrapped around fingers or wrists.
  • Avoid small lids or bottle caps for children under 36 months as these can be a choking hazard.
