Circle Theorems (First Steps)

Three worksheets helping students take the first steps working with circle theorems. Some very useful questions that allow students to familiarise themselves with looking for angles within circles and get involved in good, healthy mathematical discussion. Solutions are included.

Circles: Area of Shaded Regions

Circles: Area of Shaded Regions

Ideal for either work in class or as a homework for Y8 and above. Mainly GCSE-type questions, but a couple of particularly challenging ones at the end (will stretch the most able Y11). The questions allow students to get involved in good, healthy mathematical discussion. Solutions are included.

Types of Angles Poster A3 Wall Display

Types of Angles Poster A3 Wall Display

This high quality poster is ideal for your classroom wall, bulletin board or math display. It makes a great anchor for students (and teacher) to refer to. I have included 4 designs with different colored tittles to fit your room decor. Angle definitions and examples on the poster are: Acute, Right, Obtuse, Straight, reflex, Full, Adjacent, Complementary, supplementary and vertical. Enjoy.

Identifying Parts of Circles

Identifying Parts of Circles

This lesson is for KS4 students. I teach this lesson before teaching circle theorems. It teaches students to look at the diagrams more closely and identify particular arcs, radii, sectors, segments, reflex and non-reflex angles. Worked solutions to the worksheet are included.

Circle theorems

Circle theorems

Introducing four circle theorems are introduced: the angle at the centre is double the angle at the circumference, angle in a semicircle are 90 degrees, opposite angles in a cyclic quadratic sum to 180 degrees and angles in the same segment are equal. Differentiated questions on each slide on fluency or problem solving questions with the final problem yielding the Golden Ratio. This is the ninth lesson in the “folder of Phi” series.

Revision lessons 2

Revision lessons 2

Here are a three revision lessons I have used for my foundation students. The lessons consist of Area and Circumference of a circle. Solving Equations : letters on one side & letters on both sides. Probability of a single event.

Area of a Circle

Area of a Circle

A practical lesson to help students "discover" the area of a circle. Followed by a few examples to consolidate learning. It is essential that they have previously worked out the circumference of a circle and understand pi.

Applying Circle Theorems

Applying Circle Theorems

Used this with a top set Year 9 class where they just needed more practice applying the theorems. Used in an observation and received and outstanding. The RAG questions were just from Corbett Maths Exam Style Questions which I RAGed myself (very easy to do!). Treasure Hunts were from Maths Box. A lot of work to be completed could easily be used for a double lesson. Let me know what you think!
