How can you tell they’ve got it: Measuring angles?

If they’ve got it, you’ll see things like: Measure an angle with a protractor and read 47°; Draw an angle of 135° using a protractor; Identify which scale on the protractor to use for an obtuse angle. Or just try it together: If your child is given a protractor and an angle drawn on paper, can they measure it accurately and then draw a new angle of a size you specify?

Measuring angles

Your child can measure an angle with a protractor, like reading 47°, and draw an angle of a size you ask for.

In curriculum terms

Measure angles in whole-number degrees using a protractor; draw given angles and sketch angles of specified measure
