There are 4 codes from throughout history in which students need to break. Each code gets progressively harder leading to the final code of a simplified Enigma machine. It is impossible to solve a code if the previous one has not been cracked as each one provides vital clues for the next code. The final code (the simplifed enigma) once broken is a 3 digit number. This resource can be used in many different way. One way is buying a 3 digit combination lock and locking a box/locker full of prizes. Then send all students the presentation. Or send all students one code a week if you want to stretch it out more. The first slide needs to be edited to suit your plans.

All the resources required to teach everything on sequences in the GCSE. Includes nth terms, patterns, Linear sequences and Quadratic sequences.

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.

A great lesson where students investigate the golden ratio proportions in the face. A 10 minute starter using the same concept with the hand helps introduce the idea. They can then look at how well celebrities fit the golden ratio. Finishes with a video that shows somebody using photoshop to make a face match the golden ratio grid (a link to youtube).

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 is a fun lesson for the very able. After teaching functions and their graphs and transformations of graphs this lesson guides students in using this knowledge to draw graphical pictures. The worksheet teaches the student step by step by guiding them to draw a house with a chimney. That takes the first 20-30 minutes at which point students are directed to drawing their own.

Two lessons worth. 12 A* questions that are worth around 7 marks each. I use 6 in a lesson where I place one on each table and students get 5-10 minutes (you decide!) before moving onto the next table. The powerpoint shows step by step method and solutions for each question.

A very unique treasure hunt. Instructions for use: Students start on any question. Write down letters to answers as they go along (NOT the question they started on!) The collection of letters make a word but not in order. They can use an online unscrambler to find the word. They stop when a question sends them back to a letter they already have. It is the longest possible word where no letters repeat.

Enough for two lessons. Teaches how to calculate quartiles and the interquartile range to create box plots first. Then goes through two full examples for cumulative frequency diagrams (to be used with worksheet provided) followed by 4 practice questions with answers. Teacher could use this resource to teach the topic without any understanding of Cumulative Frequency.

Everything required to teach set theory for the iGCSE. Includes worksheets that run along side the PowerPoint. The homework worksheet with answers can also be used as a mini assessment.

Everything required to teach the Vectors chapter in the iGCSE. Drawing vectors, finding magnitudes, calculating with vectors, vectors with bearings and solving problems with vectors.

A fun resource that introduces and teaches tesselations clearly.

Students take it in turns answering questions to reveal the picture behind. First to guess the catchphrase wins. A variety of topics already created but very easy to add your own.

Students throw a soft toy at the board (I use a toy angry bird). Teacher clicks the number that the student hit to reveal a question. If it is a yellow question students get a merit. Works best with smart boards as questions will reveal themselves when hit by the soft toy.

Everything required to teach probability for the GCSE. Several lessons worth covering basic probability, sample space diagrams, experimental probability and tree diagrams. Lots of fun probability games and ideas included.

At least 3 lessons worth of content here. Starts by teaching the elimination method followed by worded exam style questions. Then teaches the substitution method and solving by plotting the two equations. Last lesson on the A and A* questions solving quadratic simultaneous equations.

Everything you need to teach Binomial Expansion. This powerpoint is designed so that students can use it by themselves to learn independently if required or as the main teaching resource by the teacher. Many colleagues have used it to teach themselves too. Method is animated to clearly show each individual step. This resource covers all aspects of Binomial Expansion including the use of Pascal's triangle, combination notation, powers of n, non-integer powers and partial fractions. 2 mini assessments plus mark schemes also included.

Method and easy demonstration for all constructions with compass and straight edge. Includes the following constructions: SAS, ASA and SSS Triangles Perpendicular bisector Perpendicular from a point on a line Angle bisector 60°, 30°, 45°, 90° angles (without a protractor) Regular hexagon inside a circle Equidistant from two points

** Students will need access to a computer and this Excel file** Created on Excel. Students need access to a computer to use this worksheet. Tasks are differentiated along the task bar at the bottom. The worksheet responds instantly to incorrect answers. Examples given to help students independent learning of the grid method.

**Students need access to a computer and this Excel worksheet** Plotting Coordinates This Excel file will plot and connect coordinates which are typed in. Fully differentiated by tabs along the bottom. Depending on the class; this could be a full lesson or an activity.
