Column subtraction 4: Lesson 2: brittle stars

Further Challenges

• Starfish are great for exploring angles! Find a picture of a starfish like the one below and identify the type of angle made between two of its legs. How many acute angles are there? How many obtuse angles are there? Are there any right angles?

Try to explore a range of starfish. Not all of them have 5 legs! There are over 1,800 different species of starfish and some have up to 50 legs!
