Did you know?

We’ve learnt that spiders are arachnids with 8 legs, but did you know that most spiders also have 8 eyes? Jumping spiders, like Portia, have two very large front eyes to get a clear, colour image and to judge distance. They have extra side and rear eyes to detect when something is moving.

Use Paws and the multiples-of-8 bar to solve the word problem.

High up in the canopy of a rainforest, five 8-eyed jumping spiders were on a hunting expedition. They were jumping from tree to tree in search of prey such as other spiders, flies and ants. One particular spider managed a record-breaking leap of 70 centimetres!

Between them, how many eyes did the jumping spiders have altogether?
