Noah was counting the animals into is ark. He counted 12 legs so how many creatures could there have been? This needs writing down and posting in our box!

I think there were 3 animals because 4×3=12

Or there could be 6 creatures

because some animals have 2

Legs and 4 legs so my suggest is

6 creatures!!!

This question is hard i need to think.

We read the story ‘one is a snail, ten is a crab’ to help with ideas. Has anyone else got this book? I have found four different ways. My favourite way is one spider and four snails.

Yes Alice I do!

i think 2 horses 4 and 1 puppy from amie

So you’re thinking about 3 – 4 legged animals. What about if there were birds? Mrs M

I worked systematically to find different numbers of animals. Does anyone know if there is an animal with twelve legs?:)-

A dodeca lion?

I think 2 roosters 2 puppy’s

2 roosters+2 puppy’s=12 legs

Twin spiders!!!

Oooppsss – conjoined spiders with only 6 legs each

I’ve never heard of a conjoined spider! Can you prove to me that these exist? Great thinking. Mr E
