🔬 Creature Classification Lab — a free maths game for kids
Sort every creature that walks into the lab — then handle the ones that belong in two groups at once.
Sorting by one attribute is early logic; sorting by two at once is set theory. Placing a dolphin in the overlap of water animals and mammals is the exact reasoning behind AND and OR, met years before the notation shows up.
How to play
- 1Creatures arrive on the conveyor belt.
- 2Send each one into the correct bin — big or small, land or water, mammal or bird or reptile.
- 3Later rounds ask for two conditions at once: lives in water AND breathes air.
- 4Venn mode gives you two overlapping rings and creatures that belong in the middle.
Frequently asked questions
- What is Venn mode?
- Two overlapping rings, each with a rule. Creatures satisfying both rules go in the overlap, which is where children meet intersection for the first time.
- What classifications are covered?
- Size, habitat, movement, mammal/bird/reptile/amphibian/fish, vertebrate versus invertebrate, warm versus cold blooded, and diet type.
- Can pre-readers play?
- Yes. The early rounds sort by size and habitat using pictures only.
- Is it free?
- Yes, free with no signup.
