This is a lesson to follow introduction of the nth term rule, which looks at pattern sequences. It is introduced as a contextual problem - a farmer who has to build a fence to separate his sheep from his goats. In this phase, students use mini-whiteboards to give their responses, before moving on to complete a worksheet (slides 18 and 19). Make sure your audio is turned on as sound is embedded in some slides. Please rate/comment/favourite as appropriate. All suggestions to improve are welcome. Dave

Level 5 introduction to probability and using the probability scale. Moves on to show how simple probability is calculated using a tube of Smarties. Class should be ready to access your worksheet of probability questions after viewing this. Please rate/comment/favourite if you download. All suggestions to improve are welcome! Dave

These slides form an introduction to the topic of standard form, explaining why it is used. It demonstrates the skill of converting normal numbers into standard form and vice versa (for large and small numbers). Slides 29-31 are the worksheets, which you can add to. Make sure your audio is switched on, as sound is embedded in some of the slides. If you use this resource, please rate/comment/favourite as appropriate. All comments to improve are welcome! Dave

Introduction asks students to brainstorm and identify as many different uses of percentages in everyday life. After this, students are introduced to the method of calculating percentages without a calculator, using 10% as the starting point and building block. (eg. Find 36% - first find 10%, then half 10% to find 5%, divide 10% by 10 to find 1%. So 36% = (3x10%) +5% +1%. Slides 28-33 are the worksheets.

This lesson introduces the general form of all straight line graphs (y=mx+c), explaining key features. Coordinate starter to begin with (make sure audio is turned on, as sound is embedded in slides). Phase 1: generate coordinates from functions. Phase 2: plot the coordinates on worksheets. Extension: Generate and plot coordinates for two non-linear functions.

A Powerpoint and Excel file which describe a coin-tossing probability experiment (what is the probability of getting 2 Heads when you toss a coin three times?) Paired activity - experiment is described on the slides and a recording sheet is provided. When the time is up, teacher asks each pair to give their results, which are typed directly into the spreadsheet. A dynamic, real-time bar graph is generated, with each entry. Follow up with investigation of how you arrive at theoretical probability by generating a table of outcomes for the coin-tossing task. Finally, discussion of differences between the two results, and how the experimental probability would likely alter if we increase the number of coin-tosses. Please leave feedback comment/rate, if you like this resource, or have any suggestions for improvement. Thank you Dave Wilson

This activity can be used with or without the volume calculations. Primarily, it is an exercise in isometric drawing of cuboids and prisms (Level 5). If you incorporate the volume calculations, this shifts the work up to Level 6 (vol. of cuboids) & Level 7 (vol of prisms). Tip: Print off all the question sheets on A4, and then place two on photocopier and reduce (A3 to A4). After guillotining, the A5 sheets stick nicely into exercise books.

Useful for a starter or plenary activity. The true/false quiz reinforces KS3 angle facts. The angle estimation quiz uses context to estimate angles in the real world. Students love the space shuttle one when I tell them that if the angle is too shallow, the shuttle would 'bounce&' off the earth&';s atmosphere; too steep and it would burn up on re-entry! Should be fairly self-explanatory. Please rate/comment/favourite. Thanks Dave

Using a real-world context (packaging for chocolates), students need to work out which design will use least material and will be most economical. By calculating the unit cost of packaging, students then work out how great the savings will be, for a planned production level. Please note: the cost of the material is 0.45 of a penny per square cm (not 45p). Worth emphasizing that. Please rate/favourite/comment. Thank you!

A maths 'general knowledge&' quiz with mathematical puzzles (Christmas themed). Please rate/comment if you like!

This is a straightforward activity where students have to complete the table of outcomes/probability space/sample space for the event of rolling two dice and adding the scores together. This leads on to calculating the probability of a particular result. Please rate/comment/favourite as appropriate. All comments suggesting improvement are welcome. Dave

A nice, kinaesthetic activity for students to investigate the volume and surface area of 3-D shapes with standard Unifix building blocks. Fairly self-explanatory! Please rate/comment/favourite. Thanks Dave
