# Maths

This week we are going to learn about angles and lines. A right angle is an angle of 90˚. This is the corner of a square or a rectangle. An acute angle is an angle which is smaller and an obtuse angle is an angle which is bigger than 90 degrees and smaller than a straight line.

Angles can also tell you how much an item has turned. A quarter turn is the same as one right angle, two quarter turns (or a half turn) are the same as two right angles, 3 quarter turns are the same as 3 right angles and 1 whole turn is the same as 4 right angles.

We are also going to learn about different types of lines. The types of lines we will learn about are horizontal, vertical, parallel and perpendicular. Horizontal lines are lines that are straight across. Vertical lines are lines that are straight up or down. Parallel lines are two or more lines that would never meet (like a set of train tracks). Perpendicular lines are lines that meet at right angles.

Have a look at the videos below to help you remember these facts. Some of these videos have tasks for you to complete in them. You don’t have to do these tasks, but you are certainly welcome to try them if you would like to. There are also some angle games on MyMaths that you can use to help you understand angles.

There are also some right angle finders that you can use to help you.

## Year 3 - Angles

Watch this video to help you with the Maths activities for the week commencing 1st June.

## Maths - Recognising lines - KS2 (Vertical!)

sorry for my spelling mistake, it's vertical not verticle! Parallel, perpendicular, horizontal, vertical.

🍎 You're cordially invited to come check out our growing library of award-winning math video animations at https://www.numberock.com 🍎 Thank you for watching...

Activity 1:  Have a look at MyMaths, I have allocated you two activities, these involve some work about lines and some about angles. The tasks are ‘2D and 3D shapes’ and ‘Angles 1’.

Activity 2:

The answers are below, make sure you check any mistakes.

Activity 3:

Try either A, B or C on page 114 in your ‘Target your maths’ book. Remember you can use your Right angle finer to help you. If you couldn’t print them off, you can just use the corner of a piece of paper.

The answers are below, do go back and check any mistakes.

Extension 1:  Have a look around your house, garden or wherever you are.

How many right angles can you find? How many acute angles can you find? How many obtuse angles can you find? Can you find any parallel or perpendicular lines?
