A set of eleven lessons (80 slides) which could be used individually or as introductions to textbook exercises. Pupils who have been absent from school and need to catch up with work would find these useful. Alternatively they could be used for revision or for class notes

Test your pupils' knowledge of Pythagoras' theorem in a motivating and engaging way with this differentiated target table. The aim is to reach a target score, set by you, by answering questions from the table. The questions are differentiated, with different point values, so pupils can choose their own difficulty level. You'll get full instructions, answers and a thoughtfully differentiated resource - everything you need for a great lesson!

Graded worksheet with differentiated Pythagoras questions, ranging from 2D to 3D, real life and contectual examples. Was offered a job based on this lesson.

A complete lesson on using Pythagoras’ theorem for 3-dimensional scenarios.
Activities included:
Starter:
Two questions involving a spider walking along the faces of a cuboid. For the first question, pupils draw or use a pre-drawn net and measure to estimate the distance travelled by the spider. This leads into a discussion about finding exact distances using Pythagoras’ theorem, followed by a second question for pupils to apply this method to.
Main:
Highly visual example and quick questions for pupils to try on finding the space diagonal of a cuboid.
A set of questions with a progression in difficulty, starting with finding space diagonals of cuboids, then looking at problems involving midpoints and different 3D solids.
An extension where pupils try to find integer dimensions for a cuboid with a given space diagonal length.
Plenary:
Final question to discuss and check for understanding.
Printable worksheets and answers included.
Please review if you buy as any feedback is appreciated!

Complete lesson on 3D Pythagoras
Includes:
> How many right angled triangles can you spot in this cuboid?
(Really good investigation starter that helps the students visualise the triangles and is afl for your next task)
Full solution provided including on the diagram.
> Examples to work through - starting with 2D Pythagoras on a 3D shape and progressing.
> 2 options for worksheet.
Option 1 - Starts with 2 questions on 2D Pythagoras on a 3D shape
- Then 2 3D Pythagoras questions finding the hypotenuse
- Then a 3D Pythagoras question finding a shorter side
- Then a "find the height" of the pyramid question
- Then find the side length of the cube given the diagonal question
Option 2 - Same questions as option 1 but the triangles are drawn for the students. Firstly with measurements and then without.
> Further extension - design your own question with model answer and mark scheme for both a cuboid and a pyramid. Template sheet provided for students to work on.
> Full solutions (same for both sheets)
> Plenary - showing the 3D Pythagoras formula and where it comes from

A Pythagoras theorem activity involving stacked right angled triangles. In order to work out the top length, you must work your way up the piled triangles using the information you know. Great for extending gifted and talented students.
Involves finding the longer side and the shorter side of the triangle.

This presentation explains in simple terms how to go about solving Pythagoras Theorem. Great lesson starter to introduce the topic or a helpful revision guide.

A lesson's worth explaining the basic skills needed in order to use Pythagoras' theorem.

Questions to check their understanding
Extension: using Pythagoras Theorem to find the length between two coordinates

Interactive MS Excel Spreadsheet. Requires macros to be enabled. Covers the following teaching objectives: Find the area of a semi-circle given two dimensions not equal to r. Find the area of a circle given its centre and a circumferential point. Find the area of a circle a rectangle of given length and width fits into exactly.

Group activity, first cut out and laminate cards. Hand one card to each student they must match their cards with the correct diagram, this puts them in groups. Then the second activity has problems on each card , one card per group, can then swap and try another one.

A complete lesson for first introducing Pythagoras’ theorem.
Activities included:
Starter:
A set of equations to solve, similar to what pupils will need to solve when doing Pythagoras questions. Includes a few sneaky ones that should cause some discussion.
Main:
Examples and quick question to make sure pupils can identify the hypotenuse of a right-angled triangle.
Optional ‘discovery’ activity of pupils measuring sides of triangles and making calculations to demonstrate Pythagoras’ theorem.
Questions to get pupils thinking about when Pythagoras’ theorem applies and when it doesn’t.
Examples and quick questions for pupils to try on the standard, basic questions of finding either the hypotenuse or a shorter side. A worksheet with a mild progression in difficulty, from integer sides and answers to decimals.
An extension task of a ‘pile up’ activity (based on an idea by William Emeny, but I did make this one myself).
Plenary:
Some multiple choice questions to consolidate the basic method, but also give a taster of other geometry problems Pythagoras’ theorem can be used for (e.g. finding the length of the diagonal of a rectangle).
Printable worksheets and answers included.

Designed to teach KS3 students about Pythagoras. The lesson includes numerous practice questions and answers that are differentiated and consists of fun activities to complete in class. This lesson includes a worksheet.

This introduction of Pythagoras’s Theorem includes two proofs. The first proof is suitable for lower ability students, the second for higher ability students. I have also included an investigation that give you an oppertunity to show your students how this important theorem can be applied within the school. The investigation canb be made in to a practicle one if you wish.
I have also included a small exercise with answers, that will allow the reinforcement of your initial introduction of this theorem.
The second proof requires a good level of algebra for a full understanding. I recommend you use this proof after covering expanding brackets and factorising in algebra.
I also like to mention to my students although this theorem is now known as Pythagoras’s Theorem who lived about 500 BC, he was not the first to have discovered it. It was known by the Babylonians and the Eygptians.
