#### Introduction to Differentiation

(0)
A presentation showing where differentiation comes from, including aspects for the students to explore themselves. There are two versions of the PowerPoint: a full presentation which includes equations, etc. and one which just has the basics, such as the graphs, allowing the teacher to write on the board without having to sketch the graphs. Suggestions for the lesson plan are noted in the PowerPoint file. There are also differentiation questions (with answers) and homework.

#### GCSE 9-1 Exam-style Questions on Graphs — 42 Questions and Answers

(0)
This resource contains 21 questions in the style of a non-calculator paper and 21 questions in the style of a calculator paper. The questions are aimed at those revising for the Higher GCSE papers and contains questions ranging from Grade 4 to Grade 9. There is also a mark scheme for each based on the Edexcel marking conventions. But the questions are suitable for both AQA and Edexcel. The documents are not formatted in the exam style, instead they are written in order of ascending difficulty, with the grade level clearly marked for easy differentiation. The questions are available in both Word and pdf format. These questions cover all of the syllabus content of graphs, except real-life graphs and scatter-graphs. There are also 6 Grade 9 questions to challenge the high-achievers. The answer to Hitchhiker's Guide to the Galaxy fans' resource problems! Reviews are really appreciated and if you have any problems or questions don't hesitate to ask. A lot of care was taken but if there are mistakes do let me know. Thanks.

#### Heat Transfer Experiment

(0)
A prepared lesson to investigate heat transfer. Ideal for Unit P1.1 of the AQA GCSE Physics syllabus, but transferable to other boards. Also excellent for ISA preparation. The experiment itself is very basic, using beakers of hot water to investigate cooling effects of conduction, convection and radiation. The pack includes a detailed lesson plan with objectives, a worksheet for the students to work through, and presentation to guide the students.

#### GCSE 9-1 Maths Graphs of Polynomial Functions

(0)
This resource is aimed at both Edexcel and AQA 9-1 GCSE with topics ranging from grade 5 to grade 8. After the lesson the students should be able to: -Recognise, plot, and sketch graphs of quadratic functions &amp; cubic functions -identify and interpret roots, intercepts, and turning points of quadratic functions graphically -deduce roots algebraically and turning points by completing the square. The resource also includes homework and answers. The files are available in pdf for compatibility but also the original docx files are included in case you wish to edit the documents.

#### Red-shift and Origins of the Universe Lesson

(0)
Ideal for AQA GCSE Physics P1.5.4. The pack includes the following: a lesson plan with a description of two possible demonstrations; a PowerPoint presentation about red-shift, the 'big bang' theory, and CMBR; print-outs for a starter exercise; a worksheet for students to do in class; a homework sheet. The presentation includes several amazing images from NASA — a fantastic way to enthuse pupils.

#### Probability Tree Diagrams - Alternate Universes

(0)
A novel approach to probability tree diagrams, that in my experience has taken away the fear of probability tree diagrams, and made the concept quite enjoyable. A particularly useful resource to have since drawing probability tree diagrams is a pain. Lesson plan suggestions are in the notes of the PowerPoint presentation. There are also two worksheets that go with the presentation, and another worksheet (with answers) to do individually.

#### GCSE 9-1 Maths Higher Graphs of Functions

3 Resources
This bundle contains lessons which cover polynomial graphs, reciprocal & exponential graphs, and trigonometric graphs. There are also 42 exam-style questions on graphs for plenty of exam preparation! The lessons cover grades 5-8 and the exam style questions cover grades 4-9. The grades of the topics and questions are clearly marked for easy differentiation.

#### GCSE 9-1 Maths Advanced Graphs

(0)
This lesson covers all the advanced graphs of functions in the 9-1 GCSE, suitable for Edexcel and AQA. This includes reciprocal graphs, exponential graphs, and sine, cosine, and tangent graphs. The topics cover grades 5-8. It assumes students have already been introduced to quadratic and cubic graphs. The lesson objectives from the syllabus are: Plot reciprocal and exponential graphs Recognise, sketch, and interpret graphs of the reciprocal function, exponential functions and trigonometric functions (sin x, cos x, tan x) for any angle The PowerPoint is a very flexible resource as it can also be divided into two separate lessons: Reciprocal &amp; exponential graphs and trigonometric graphs. This can be useful if you would like the students to spend more time doing independent work on the topics or if you will not be covering grade 8 topics such as trigonometric graphs.

#### GCSE 9-1 maths lesson on functions

(0)
This resource covers function notation, evaluating functions, composite functions, and inverse functions. The PowerPoint covers the topics with many examples and illustrations. The level of the material ranges from grades 6 to 8. Differentiated worksheets are included WITH ANSWERS. 1. Grade 6 worksheet concentrates on function notation and evaluating functions. 2. Grades 6-8 worksheet also has questions on composite functions and inverse functions. There is a bonus 'bank of functions' in the form of an Excel file. The Excel file can be used as an easy way to find outputs for different inputs if you want additional questions/examples, or it could be an opportunity to show how spreadsheets use functions. A very flexible resource. Reviews are really appreciated, so please take the time to rate and comment on the resource. Thank you.

#### Connect Four App for percentages or rounding

(0)
Simple but effective resource - please rate! Three versions of connect-4 to encourage students to interact: 1) with percentages on the virtual board, where students convert them to decimals (or fractions); 2) with a random number generator and different rounding methods, where students try to round to the correct degree of accuracy; 3) create your own by adding a file named input.txt in the same folder with the desired text for the virtual connect four board. The coloured counter is placed if you pick a colour and click on the desired part of the board.
