Straight Line Graphs

Straight line graph lesson written by an outstanding practitioner who leads on Mastery. The extension part of the lesson is on non straight line graphs (Quadratic and Cubic Graphs). The resource contains:1 Power Point presentation contains 38 slides, visual and interactive, checks understanding. 5 Worksheets with answers. Choice of Grids to use -10 by 10 or -18 by 18. The lessons start with making sure students have the necessary understanding of multiplying negative and positive numbers. It ensures that students can substitute in to an expression. The resource contains worksheets with answers. It also has slides to check students understand parallel lines, gradients and y intercept. Power point animations used to show how a graph is plotted.

Drawing linear graphs

Drawing linear graphs

The starter is a recap about how to solve equations as that is what we had done in the previous lesson. There is then a thinking hard task creating equations to solve. This is followed by 3 examples that are all animated on how to draw their graphs and notes to put into their books.There are differentiated question with answers Plenary is writing a tweet

Solving Simultaneous Equations Graphically

Solving Simultaneous Equations Graphically

Solving Simultaneous Equations GraphicallyThe start of the lesson involves recognising the properties of linear functions both algebraically and graphically by identifying the gradient and intercept values. The development phase builds on this by teaching how to solve a pair of equations simultaneously using graphical methods. As learning progresses students are challenged to solve equations in the form ax + by + c = 0.Differentiated Learning ObjectivesAll students should be able to plot a linear function using two points.Most students should be able to solve a pair of simultaneous equations with integer solutions graphically.Some students should be able to generate and solve a pair of simultaneous equations graphically.

Gradients of curves (GCSE 9-1)

Gradients of curves (GCSE 9-1)

Full lesson with animated examples and worksheets with answers on the topic gradients of curves for the new GCSE 9-1 Specification (R15). The learning objectives are based on Edexcel's teaching guidance, which is where the worksheet exercises were also taken from. I taught this lesson to my top set year 11s, using the note sheet as a template for pupils to write down key words and examples. Please leave a review!

Equations of a Line Assessment

Equations of a Line Assessment

A starter is included with this assessment. The assessment is aimed at pupils who are working at a grade 5-9. The assessment looks at; midpoints, equations of a line, parallel lines and perpendicular lines. I have used this assessment with my top year 9 set. I found this assessment gives me a more accurate picture for what grade they are at with this particular topic. Answers are included for both the starter and assessment. Any feedback would be appreciated.

Discovering functions and their graphs

Discovering functions and their graphs

A worksheet that students use alongside a graphing resource (not included - I use desmos.com) to find out for themselves how the different equations make different lines and how changing various coefficients affects the line. A Powerpoint to flick through at the end with a fun "Simon says" plenary should round off the learning.

Half lesson, one sheet test on straight line graphs

Half lesson, one sheet test on straight line graphs

I have written a number of mini tests to fit perfectly on to one sheet of A4 (I actually print them 2 to a page so A5!). These tests can be completed and peer marked in the same lesson and will be reused by you many many times over the years. Really easy to mark due to the layout of the test paper and the markschemes included. This tests all types of plotting linear equation questions that can be found in the GCSE. Ideal for finishing the straight line graphs chapter. I use it for a pretest before the official chapter test.

Catch Up Questions - Algebra

Catch Up Questions - Algebra

This is a booklet of 44 worksheets that can be used for either revision, homework or those students who have missed work with each containing a QR code that will scan to a short tutorial video. It is designed to cover the entire GCSE algebra curriculum. I have tried to order the sheets in a logical way, although not necessarily in "difficulty" order, the topics are grouped. Answers are provided.

Mapping Diagrams RAG Task

Mapping Diagrams RAG Task

Pupils choose which colour they feel confident attempting. If they are really confident they should choose green, the secure option, if they are struggling they should choose the red or amber option (foundation – basic assessment of skill, amber is a little bit harder).Pupils show the questions, working out and answers that they have attempted in their class book.Pupils self assess or peer assess at the end of each activity to show themselves how much progress they have made.Answers provided. Terms of use; Please use only by the customer paying for the resource.Printing tip; Print - fit to page or fill entire page so they only print on A4. I have also included a second copy with a label of printing because my lovely reviewer gave me a valuable tip about cost of ink so I have changed the background to white to make it cheaper.
