That flower is beautiful, isn't it?
I love the vibrant colours and the geometric shape.
Mmm. That's got me thinking. If I wanted to try to draw that shape accurately, could I?
How do artists, engineers and architects draw accurate, regular shapes?
I think I'd need to know the side lengths, but is there something else?
How many regular shapes can you draw? Give it a go.

So, are you ready to learn more about angles?
You may find this page in your home learning pack is a useful place to start. Complete what you can, then add to the page as your understanding grows throughout the week. We'll share ideas and answer any questions you may have when we meet on Friday.

What next? Well, here are a couple of activities to get you started. If you are able to print at home and you have your parents' permission, you may like to try the activity sheet below. Cut out the Pac Men (and women?) then use their mouths to test the different angles you find in your home and garden. Try measuring the angles between petals on a flower or in the objects around your home. What do you notice? What patterns will you discover?
Extension Opportunity: Make an origami set square
Those Angle Eaters were quite handy, but what if you don't have a printer to hand? Well, if you're up for an extra challenge, this exploratorium link shows you how to fold your own origami protractor (or set square) using simple everyday materials. Check it out if you're up for it.

Angle Testers - a simple but handy tool when you don't have a protractor
The tools above help us measure angles, but sometimes it's enough just to be able to compare and match angles. That's where an angle tester can sometimes come in handy. You can make one using cardboard from your recycling bin and the split pin in your home learning pack (look carefully it's only little).
The video below shows how a teacher uses one in class to check whether his students are able to visualise angles, but it could be used for all sorts of things. If you're helping with a woodwork project for example, you can use it to help ensure your cuts are always parallel, or if you're copying a sewing pattern or creating an artwork and need to transfer an angle, a simple tool like an angle tester could prove just the thing.
If you're interested, check out the video and create one of your own. If you weren't able to make the tools above you may like to try using it to compare angles around your home and garden too.

Classifying Angles
When we’re talking about angles with other mathematicians like us, it can help to have a common language.
The video below introduces a few common terms we use to describe angles. You may like to check it out before playing the Angles Connect 4 game in your home learning pack.

The button below links to a handy reference from abcteach which captures some of the same ideas too.
Angles in play
This next game helps you practise identifying common angles of rotation by imagining you're playing with a puppy and a sprinkler in your yard.
If you're on a computer rather than an iPad, you may like to give it a try.
