Guess the Angle/Make the Angle
This page has a single activity on it, which can be used to practice two key skills when working with angles. The first activity is to practice estimating the size of angles. The second is to practice making angles of a given size.
Guess the Angle
How good are you at estimating the size of angles?
For each angle shown, estimate how big you think the angle is, and type your estimate in the textbox for that angle.
Press the "Click to Reveal" button for each to show the actual angle of each question.
Now grab one of the orange points and move it around to make a new angle, and repeat the whole process.
Keep going until you are a master of estimating angles!

Make the Angle
Can you make a given angle?
For each of the following angles, try and move the orange points to make the angle. Once you are happy, "Click to Reveal" the angle and check how close you were.
1. 40 (degrees) 2. 75 (degrees) 3. 120 (degrees) 4. 90 (degrees) 5. 215 (degrees)
Make up some of your own angles and type them in the textbox. Can you make the angle you have set yourself?
Keep practising until you can make any angle in no time at all!

Ideas for Teachers
This activity is an excelent resource for when all the students have access to computers. This could be done as a homework, to practice until they are confident, and then use it at the start of the next lesson to check by getting individuals up to the board.
An activity I have used before when doing angles is to get a pupil to the front and for them to make an angle with their arms, and for the rest of the class to estimate the angle. It is a really good starter, but without a way to check can be unsatisfying for the students. So why not do it in front of the board, and use this to "record" the angle the student makes with the arms. Then that student can also be involved in estimating, and the class can get an answer too.
