# Interior Angles of Polygons

Students learn how to calculate interior angles of polygons.  Learning progresses from finding an interior angle using 180 - exterior angle to calculating the sum of all the interior angles for any regular polygon.  More able students are challenged to find the number of sides a polygon has when given its interior angle.
##### Differentiated Learning Objectives
• All students should be able to calculate an interior angle of a polygon when given its exterior angle.
• Most students should be able to calculate the sum of the interior angles in a regular polygon.
• Some students should be able to calculate the number of sides of a regular polygon when given an interior angle.

#### Literacy in Mathematics – Creating Problem Solvers

Last year my school had a OFSTED trial inspection. Whilst the maths team recieved favourable feedback the inspectors noted a need for a focus on whole school literacy. Because of this I was asked to demonstrate how we develop student’s literacy in mathematics. Literacy in Mathematics By developing student’s literacy in mathematics we aim to […]

#### Angles in Polygons

There are two key learning points when solving problems with angles in polygons.  The first is to understand why all the exterior angles of a polygon have a sum of 360°.  The second is to understand the interior and exterior angles appear on the same straight line. Students can be told these two facts and […]

#### Getting Ready for a New School Year

When getting ready for a new school year I have a list of priorities to work through. Knowing my team have all the information and resources they need to teach their students gives me confidence we will start the term in the best possible way.  Mathematics Teaching and Learning Folder All teachers receive a folder […]
