# Angles

### What to do with this activity?

An angle is the space between two lines at the point at which they meet. We measure an angle in degrees. Think of a round clock on the wall. If the hand of the clock goes all the way around, that's 360 degrees. If the hand only moves from 12 o'clock  (where the hand points straight up) to 3 o'clock (where the hand points to the right) that's a quarter of 360 - an angle of 90 degrees.

We usually understand angles without thinking about it. For instance, we know that shooting from straight in front of the goal (an angle of 90 degrees) is easier than shooting from the sideline (say 30 degrees). In this case the lines are imaginary, but you can draw a picture and work out the angles using a maths tool called a protractor.

A protractor is the half circle shaped maths tool in the picture above. Your 5th or 6th class child might be learning to use a protractor in school. Find out more about using a protractor with this link from Ambleside Primary.

If you or your child would like to know more about angles have a look at this explanation from BBC Bitesize. And get to recognize angles with these enjoyable online games - from BBC Bitesize, and another from BBC, Kung Fu Angles

• #### Why am I doing this?

Maths makes sense to children when they use it in everyday life - like measuring things, working out distances, estimating food for dinner or money for groceries. The more opportunities you give your child to use the maths they learn at school through everyday activities the more they will understand and enjoy working with numbers.

• #### How can I do more?

Discuss maths that you see around you. For example, talk about sales in shops – half price, 25% off, what is good value? Or how much will the item cost after the discount?
