Students plot eight straight lines that miraculously turn into a Christmas Star :) Using y=mx+c, and then extending with a worksheet asking questions about parallel lines, and finding new equations. Plotted lines can also be used to talk about reflected functions (about x- or y-axis) and even inverse functions (2nd 4 lines are inverses of the 1st 4), as well as restricted domains (or inequalities for younger students).

Use this template to get your students racing to make the longest Christmas paper chain :) I have filled in some questions - add more of your own - then print out and pre-cut the strips. Students take a strip, answer the IGCSE question, and if their answer is correct they get to add it to their chain. Have a stapler ready for them :)

Very simple graph to work through with your students before they tackle problems on their own involving distance-speed-time graphs.

A tarsia puzzle to assemble, matching trinomials with their binomial factors. Good for practising either binomial products or factorising :)

A slightly more challenging exercise to strengthen factoring by grouping (including sign changes) and DOTS with some tricks. Made for Algebra I, or Year 10 IGCSE. Includes an intro to thinking about factoring trinomials.

Consolidating activity of shading valid regions of linear inequalities. Ends up leaving a heart unshaded :) Includes some challenges with limited domains. Discussion after can include symmetry and reflection of lines across y-axis.

A very very basic worksheet allowing students to investigate the trig ratios by measuring sides, and to discover that they are constant. Includes an old trig table as a reference. Students need their rulers and calculators to complete the task.

Exploration into similar triangles through drawing enlargements on an A3 sheet - students can decorate and make patterns etc. This leads into your own teaching about similarity. Then, my Smartboard lesson to summarize the properties of similarity, and how scale factors affect areas and volumes, with a worksheet that goes alongside the presentation. Smartboard objects show nicely how several of the original 2-D or 3-D shapes fit into the enlargement.

Rote practice exercise taken mainly from the textbook (Pearson Edexcel Mathematics), now with Memes :) Basic trinomials (a=1), discovery of sum/difference of cubes special products+factors, and an intro to using factored trinomials to solve quadratic equations.

A very simple worksheet to help guide students through a reflection on the old year, and some goal-setting for the New Year. You can edit and beautify it to suit your needs! The idea is to help students develop their “Growth Mindset”. There is also a space to encourage them to think about their “big rocks, pebbles, sand” (from Stephen Covey’s 7 Habits) after I did a quick demonstration of filling the “time jar”.

Year 13, C3 Chapter 5 - transformations of functions, with a review of C12 transformations included. This is just a simple worksheet to do together with your class, to go over the basic transformations with an example.

A crossword covering all the basic geometry vocabulary, with the solution. Created it for my grade 8 students :) It really challenged them after the Spring Holiday!

This resource is for Year 12 A-Level students working through the C2 book; an introduction to chapter 8. It gives a space for students to draw the angles with guidance from the facilitator, and to discover the reduction formulae for themselves, and to set up the idea of the CAST diagram. A short quiz follows with 20 questions, mostly straightforward but with some extension questions.

Discovery Activity. Using constructions, students create triangle incentres and circumcentres, and see for themselves that they are the centres of the circle. How exciting! Did the activity with my Grade 10 Geometry Class, it took around 30 minutes. I have just added a second part with an application question. Modify it to suit your area by putting a picture of your own regional map :)

Students have to try to draw a shape with given information, and NOT let it be a parallelogram. They find that some are impossible - giving rise to the minimum conditions to prove a parallelogram.
