Regular and Irregular shapes
Label each shape either regular or Irregular. Using mathematical language can you explain the difference between a regular and a irregular shape.
Quadlaretal ChallengeHow many different quadrilaterals can you draw. Don’t forget to use a ruler.

3D Shapes
Match the net to the 3D shape
Net Challenge
Y5 Shape, Space and Measures
3D Shape Challenge
Visualise the different numbers of edges, faces and vertices.
Write the correct number of edges, faces and vertices for each 3d shape.
Y5 Shape, Space and Measures
Draw a line to match the angle to the fraction of the turn, then match the fraction of the turn to the name of the angle.
A minute hand starts on a number, it makes a clockwise turn that is more than 90° but less than a half turn. It finishes on the number 9.
What could the starting numbers be?
Y5 Shape, Space and Measures
True or false? Both missing angles marked x are 130 degrees.
Which line has a missing angle of 35 degrees?
Paddy thinks that his missing angle is smaller than Kim’s.
Is he correct? Explain your answer.

Regular shapes have sides that are all equal and
interior (inside) angles that are all
equal. Irregular shapes have sides and angles of any length and size

True or false? Both missing angles marked x are 130 degrees.
Which line has a missing angle of 35 degrees?
Paddy thinks that his missing angle is smaller than Kim’s.
Is he correct? Explain your answer.
True
B
The missing angles are both 65 degrees so paddy is not correct.
