Ball Drop DIY for Tabies

Object Permanence Activity for Tabies

By the time all three of my children hit their first birthday, they were super busy and ‘into everything.’ This of course is great, but also super exhausting! Over the years of observing, I’ve found that you can’t honestly go wrong with a bit of DIY. This object permanence box / posting activity is basically a much, much cheaper version of those fancy Montessori wooden boxes…

You will need:

  • Small cardboard box (we used a fold-able style box from a recent parcel
  • Wooden balls or similar. Just so long as what you use doesn’t present a choking hazard!
  • Sharp craft knife
  • Pencil
  • Coloured pens (optional)


  1. Use one of the balls as a guide for the size of the holes. Draw around it with a pencil on the underside of the box – this is so your toddler can easily open the box and release the balls again.
  2. Repeat step one 4-6 times
  3. Cut around the circles with a craft knife
  4. Colour code (optional)


E did it over and over, eventually figuring out how to get the balls back out of the box too – I’ve posted a little video over in Instagram stories so you’ll be able to see how it works too.

For reference, E is now 14 months but you could try a simplified version from around 12 months. He wasn’t yet ready for the colour coded aspect, although this will come in handy at a later date!


  • Hand-eye coordination: getting the balls into the hole
  • Problem solving: figuring out how to put the balls in and out.
  • Language development – its a good opportunity to talk about colours!
  • Crossing the mid-line – dominant hand moving across the body to reach for the balls.
