Deepen understanding of how to calculate angles on a straight line by using this resource.

This Year 6 Calculate Angles on a Straight Line Varied Fluency worksheet helps children use the knowledge that all angles on a straight line add to 180 degrees to calculate the value of missing angles. Children will solve a reasoning problem linked to facts about angles on a straight line then find possible answers that satisfy a problem. Finally, they will identify an error in a child's calculation about angles on a straight line. All answers are also included so that marking is as easy as possible!

Note: column A uses numbers that are multiples of 5 and column B uses a range of numbers.

A varied fluency resource is also available for this small step.
