What is Padlock Pandemonium?
Padlock Pandemonium is a counting game for young mathematicians and perfect to add to the collection of classroom or home-school maths games.

It is also a wonderful busy activity for parents of pre-schoolers to Year 2 children for restaurants and other places where quiet play for active fingers is useful.

How it is Played
Children count the number of holes on the key tags and then find the matching padlock. All manner of items can be clipped into the padlock for students to unlock and release from their captivity (These items are not included) However, they can include aliens or geometrical solids... or whatever. Feel free to check out some of the items we have available to supplement this game if you don’t have toys or counters lying around the classroom that could be co-opted into playing Padlock Pandemonium.

Padlock Pandemonium can be played individually or in groups up to 4. It can also be played as a race to see who can liberate the most toys or just as a happy play time.

This game is wonderful for fine motor skills in manipulating the keys and padlocks as well as counting up to 20.

Design Features
The key tags have been designed with holes large enough for even 2-3 year old counting fingers to easily distinguish the one hole from the next.
