It’s a lot easier to have legs in pairs: 2 legs for people and birds, 4 legs for cats and bunnies, 6 legs for bugs. The one odd man out is the starfish. Most of these prickly, scratchy ocean friends have 5 legs, but there are over 1,800 types of starfish, and some can have up to 50 legs! That’s a lot of counting on toes.
Lace up: Hold up 5 fingers to pretend your hand is a starfish!
Jog: If you have a 5-legged starfish, a 12-legged starfish, and an 8-legged starfish, which one has the most legs?
Sprint: Which 2 starfish have 13 legs together?
Hurdle: If you have a pile of pet starfish with either 5 or 8 legs, how many of each type must you have if they have 26 legs all together?
High Jump: If you stick 50 pet starfish on your 4 bedroom walls to decorate, can you put the same number of stars on every wall? If not, how many leftover starfish do you have? (Assume each star touches only 1 wall.)
Answers:
Lace up: See if you can hold up 5 fingers!
Jog: The 12-legged starfish.
Sprint: The 5-legged star and the 8-legged star.
Hurdle: Two of the 5-legged ones (10 legs between them) and two of the 8-legged ones (16 legs between them).
High Jump: Not quite – you’ll have 12 on each wall, with 2 starfish left over.
