#### Simplifying Algebraic Fractions

A straightforward lesson and differentiated or staged worksheet for simplifying algebraic fractions. We start with simple multiplication / division and then through expressions which require factorising. Perfect for Middle ability Y11's, a brighter group might want some further examples of non-monic quadratics as an extension activity

#### Negative Number Challenge

A number of activities to consolidate rules when working with directed numbers.
A good starter activity to use is an addition pyramid starting with some negative numbers
As a plenary I ask the students to tell me where they started and why....

#### Classifying Quadrilaterals

A set of activity sheets and presentation/lesson for KS3 students to cover the properties of quadrilaterals. Explains line / rotational symmetry, and how/why we mark equal angles, equal and parallel sides.
The plenary works as a 'mystery' and checks learning of students by getting them to ask questions that distinguish two shapes from each other.

#### Adding and Subtracting Fractions - Lesson

KS3 / GCSE Lesson Plan. A clear powerpoint to explain how to add/subtract fractions. Ideal for first lesson on topic.

#### Missing Interior and Exterior angles in Polygons

A two lesson set of notebook files covering finding the exterior and interior angles of regular polygons

#### Codebreaker - Algebraic Substitution

Suitable for a lesson activity or homework for a Foundation GCSE or KS3 teaching group. Students find the values, convert to letters and an easy progress check can be made by asking the students what it spells!

#### Revision Sheets - Algebra, Number, Fractions/Decimals

Three examples of a sheet that I enlarge to A3 to give students general purpose revision on these topics. Most suitable for a lower ability GCSE or any KS3 maths class. The templates can be changed for any topic once youve used them.

#### Factors, Multiples, Primes into Venn Diagrams

A lesson to remind students how to classify types of number ideal for Ks3 or Ks4 Foundation GCSE.
See my Free "Bingo" resource for an ideal starter or plenary depending on the group.
The worksheets allows students to do a bit of fun shading, and likewise also introduces Venn Diagrams which have been added into the GCSE curriculum.

#### Multiplying Fractions

A nice clear powerpoint with some practical problems, ideal for lower ability students

#### GCSE Reverse / Compound Percentages Revision

A revision powerpoint for the two main ways in which percentage understanding tends to be assessed at GCSE - reverse percentages, and repeated percentage change. This could also be split into two lessons if time is not an issue. Two methods of finding reverse percentages are inlcluded, along with an activity to get students thinking about the decimal multiplier effect.

#### Codebreaker Activity - Factors, Multiples, Squares, Primes

An exercise designed to recap or revise all areas of number work that involves HCF, LCM, Powers, Roots etc suitable for GCSE or KS3 students. I use this as an end of unit assessment and either make A3 sheets to share or individually as a homework. The answers will spell a question that then needs to be answered and can be modelled at the end of the lesson as a plenary. A simple extension task is to ask students to test each other and make their own codes - I have also set this for homework in the past.

#### Terminating and Recurring Decimals - Recurring Decimals to Fractions

A big value bundle which would form the basis of a 2 or 3 lesson block on this topic.
First lesson - why do some decimals terminate and some decimals recur? - getting students to find for themselves through division and investigation that this relates to the prime factors of the denominator.
Second / Third lesson - plenty of work / practice including a well graded Mild / Hot / Spicy / Inferno sheet for this tricky topic.

#### Area and Volume Scale Factors

A notebook file for GCSE students detailing how to find the area / volume of similar shapes

#### Pythagoras Investigation

An investigative lesson where students can "discover" Pythagoras' theorem. Note - you will need to give each group of students a large number of accurately cut squares eg 6 x 6, 9 x 9 which I have not supplied. With prompting students should be able to establish and generalise not only that when the three squares form a right angled triangle, then when they dont form a right angle what this means with regards to the opposite angle!

#### Evaluating Zero and Negative Powers

A clear and straightforward Notebook file to explain what these indices represent. Can be used in conjunction with GCSE textbook or suitable worksheet although there are plenty of examples on screen

#### Standard Form Conversions and Calculations

Two nice notebook files for at least two lessons on Standard Form.

#### Ratio and Proportion - 5/6 lesson bundle

A Bundle of Notebook and Powerpoint Presentations introducing ratio, simplifying, unitary form, dividing into a ratio and some basic proportion.

#### Currency Exchange GCSE Questions Revision

A lesson focussed on answering these common questions, with some reverse rate questions thrown in to keep things interesting!

#### Solving Quadratics By Factorising

A straightforward lesson on this essential skill with a differentiated worksheet, with a few non-monic equations, and some equations that need to be rearranged into the correct form first.

#### Area and Volume of Similar Shapes

A complete lesson worksheet and starter activity for students to discover the link between length scale factor and the area/volume of similar shapes and/or solids. Could be split into Area for one lesson and then volume for the second.
