Get Your Students Finding Missing Angles

Once your students have mastered the skill of drawing and measuring angles with a protractor, they’re ready to tackle more advanced concepts. One such concept is finding the size of an unknown angle in a variety of mathematical contexts. 

This digital maths game has been designed by our experienced team of teachers to help your students find the missing angle in a variety of angle types. Students are required to use their known angles facts along with addition and subtraction to find the missing adjacent angle on a variety of diagrams. The angle types included in the resource are:

• Right angles
• Straight angles
• Acute angles
• Obstuse angles
• Reflex angles
• Angles at a point

Three multiple-choice options are provided. If students choose the incorrect answer, they are directed to a “Try again” slide, which allows them to return to the previous question for another attempt. If the student chooses the correct answer, they are directed to a “Hooray!” slide and progress to the next question. The resource includes 12 questions in total.

Use the dropdown menu to select the Google Slides version of this resource. Be sure to operate the presentation in Slideshow mode to enable the interactive features.

This resource makes a great revision activity once your students have already had some experience with finding missing angles.
