Students need to learn the difference between complementary and supplementary angles, so that they can find the value of unknown angles without using a protractor.

This Complementary & Supplementary Angles Rapid Recall Routine will provide 7-10 minutes of engaging daily practice for your students to recite, recall and apply their knowledge and understanding of complementary and supplementary angles. 

Rapid Recall Routines are a quick way to revise, review and reinforce concepts to ensure long-term retention.

Students recite and recall the definitions of complementary and supplementary angles, as well as a memory clue to aid memorisation. They can then apply their knowledge and understanding to identify complementary and supplementary angles and calculate the measurement of the unknown angle without using a protractor. 

This Rapid Recall Routine can be used as a whole class warm up, a small group consolidation session or for individual practice and revision. The slides can be used as a digital presentation or printed and used as flash cards.
