#### Angles in a Triangle

This lesson covers the full range of attainments for missing angles in a triangle. It starts by recapping prior knowledge on angles on a straight line and around a point before moving onto the basics of angles in a triangle. This lesson allows the topic to be differentiated for a variety of attainment levels and could easily be adapted to meet the need of higher or lower attaining groups through missing out specific examples.
The lesson does not look at the specific angle properties of isosceles and equilateral triangles, however, I do have a lesson on this available. This lesson spends time really allowing students to build an understanding of angles in a triangle and build change though the interleaving of previous learning on angles and through the involvement of forming and solving a variety of equations.
The lesson includes;
Starter
Introduction to the topic in small chunks
Opportunities to practice basic skills through a collaborative activity.
Clear modelling through “I do” and “You Do” examples.
Multiple choice questions to draw out misconceptions.
Differentiated worksheet.
A challenge question.
The lesson includes the solutions and is fully animated which will make it perfect for delivering live remote lessons.
