About Which Is Bigger?
Big animal pictures appear with an arrow above them. An arrow pointing up asks for the animal that is biggest in real life, and an arrow pointing down asks for the smallest. The pictures are all the same size, so your child has to think about the real animals, from an ant to a whale.
How to play
- Look at the arrow: up means bigger, down means smaller.
- Think about the real animals, then tap the right one.
- On a computer, press 1, 2 or 3 to choose an animal.
