 'Slope' tells you how much something slants upwards or downwards.

# Shapes (Easy)

Just to remind you: shapes that do not have volume (they are flat) are called two-dimensional (2D), e.g. the square and the circle. Shapes that have volume are called three-dimensional (3D), e.g. the cube and the sphere.

This is an 'odd one out' style of quiz. In 11-plus non-verbal reasoning, odd ones out can be really tricky. In this maths quiz, things are a little simpler, but you still need to use all your skills to work out which one is odd.

Remember to take your time, read the questions carefully and eliminate any answers that are obviously not correct. If you get any wrong, don't worry. Read the helpful comment which appears once you've played the question and try again.

Don't be the odd man out - do this quiz and have fun! When you get 10 out of 10, move onto our next quiz on shapes.
