Comparing Angles
Is it smaller than, equal to or bigger than a square corner?
What your child practises
Children learn what an angle is and compare angles directly (laying one over another) and with a right angle, such as the corner of a page. Degrees come later, in Grade 4.

Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
Look at the angle. Compare it with a right angle (a square corner).
- the same as a right angle
- bigger than a right angle
- smaller than a right angle
Show answer
bigger than a right angle
Hint: A right angle is a square corner. Smaller angles are narrower. Bigger angles are wider.
Question 2
Look at the angle. Compare it with a right angle (a square corner).
- smaller than a right angle
- the same as a right angle
- bigger than a right angle
Show answer
smaller than a right angle
Hint: A right angle is a square corner. Smaller angles are narrower. Bigger angles are wider.
Question 3
Look at the angle. Compare it with a right angle (a square corner).
- smaller than a right angle
- bigger than a right angle
- the same as a right angle
Show answer
smaller than a right angle
Hint: A right angle is a square corner. Smaller angles are narrower. Bigger angles are wider.
Question 4
Which is wider: a right angle or an angle that looks like a sharp point?
📐- the sharp point
- they are the same
- you cannot tell
- the right angle
Show answer
the right angle
Hint: The sharper the point, the smaller the angle.
Question 5
Look at the angle. Compare it with a right angle (a square corner).
- the same as a right angle
- bigger than a right angle
- smaller than a right angle
Show answer
bigger than a right angle
Hint: A right angle is a square corner. Smaller angles are narrower. Bigger angles are wider.
Question 6
Look at the angle. Compare it with a right angle (a square corner).
- the same as a right angle
- smaller than a right angle
- bigger than a right angle
Show answer
bigger than a right angle
Hint: A right angle is a square corner. Smaller angles are narrower. Bigger angles are wider.
