I am an experienced teacher dedicated to creating fantastic resources that engage pupils. My resources give teachers examples that they can model with pupils before giving pupils the chance to practice plenty of example questions. My pupils love answering questions using the catchphrase activity - I have found it really keeps them on task and engaged (especially if there is a small prize for whoever answers the catchphrase correct!)

Included is the following: Re-cap on finding the radius of a circle from its equation Re-cap on understanding that two lines are perpendicular when gradients multiply to -1 Two examples on powerpoint & word document (see attached) that allow the teacher to model how to find the equation of a tangent to a circle. It is scaffolded into three steps: Step 1: Find the gradient of the radius to a given point on the circumference, Step 2: Find the gradient of a tangent and Step 3: Finding the equation of a tangent. One page (7 different questions) requiring pupils to find the equation of tangents. Q6 and Q7 provide extension opportunities. Plenary question - AQA exam question.

Transformations - GCSE Maths Revision

Transformations - GCSE Maths Revision

(2)
This resource covers both performing and describing transformations. It is designed as a revision resource for foundation AQA students prior to their GCSE examination. It is in publisher and can be printed as a booklet onto A3 paper (folded) in order to turn it into an A4 booklet. There is four pages. Page 1 - teacher demonstrates the four transformations (see image). Page 2 - six practice questions that ask students to perform a variety of transformations / combined transformations. Page 3 - teacher demonstrates how to describe transformation. Page 4 - eight questions that ask students to describe single transformations. Pages 1 and 3 are included in the powerpoint presentation should the teacher wish to demonstrate on the board. Personally, I think it is best to use a visualiser. It covers transformations, reflections (including y=x), rotations and enlargements (positive and fractional). It therefore covers topics tested on AQA Foundation grade 1 to grade 5.
Forming and Solving Equations when given SIDE LENGTHS and AREA of TWO SHAPES in ALGEBRA

Forming and Solving Equations when given SIDE LENGTHS and AREA of TWO SHAPES in ALGEBRA

(1)
This resource is perfect for teaching problem solving style algebra questions (e.g. suited to the new style 1-9 GCSE questions). It is split into two sections, both involve forming equations with 'x' on both sides and solving. Section 1: Students are given two side lengths in algebra (e.g. opposite sides of a rectangle) that are equal. Students then need to form and solve an equation to find the value of 'x'. Section 2: Students are given a rectangle and a triangle. Students need to use the algebraic side lengths to find the area (e.g. side lengths of 2x + 4 and 3 would create an area of 6x + 12) and then need to form and solve an equations to find the value of 'x'. Extension: Students to substitute their values to find the area. This is also a ueful check to see whether they have the correct answer. Answers included in the notes section of the slide.

Forming and Solving Equations - Worded Questions "I think of a number"

(1)
Ideal resource for introducing pupils to forming and solving equations. All questions are of the style like the following. " I think of a number. I times it by 5, then subtract 3. My answer is 17. What was the number I was thinking of?" Form an equation and solve. It starts with asking pupils to create 'one-step' equations, then moves onto two-step equations. There is a two sided worksheet with plenty of questions on both one step and two step equations. I have also included an extension slide with three step equations and double sided eqautions. This resource is tried and tested on all levels of pupils / all years and has worked really well.
