Two-way tables are very popular questions, and great for getting learners to think logically. Progressive tasks from simply filling in the missing numbers through to creating tables from scratch. The common standards require learners to use two-way tables to answer questions on conditional probability so I've included a recap quiz that does just that - asks probability questions on a colourful quiz. Plus a lesson plan, so everything you need for a lesson or two. All images ©2015 Colin Billett

Some real, some made up by me, GCSE style questions.

Typical GCSE questions put into a powerpoint for group discussion, and worksheets for learners.

<p>Ten multiple-choice questions, with answers, in a PowerPoint.</p>

Four games to play to reinforce solving simple equations and substitution, so quite suitable for year 6 and key stages 3 or 4. Throw the dice, and match the equation to the score. Claim that tile, and the next person throws. All solutions are in the range of 1 - 6, so easy arithmetic. But game can be adapted any way you like - solve all the equations first, then play the dice game to make three in a row, or four in a row. The second set is throw the dice and substitute the scores into the expressions, then find the numbers in the grid. Give feedback please, on suggested improvements.

PowerPoint presentations on using the grid method, plus a poster and an investigation into multiplying diagonals. Worksheets to practice multiplying and factorising two parentheses, and lots of questions on solving quadratic equations, including GCSE examples. Plus questions on matching quadratic graphs to expressions. All answers provided either in Word and/or PowerPoint. Everything you need for a couple of lessons at least.

These have been enormously popular. I teach a number of people who are far more artistically minded than mathematical, so I produced some visual displays to illustrate equivalences. Run the PowerPoint, or print off some slides for display. I've also added a few posters by way of example of how you might use the individual slides. For classroom activities I’ve included five pages of shapes to color for fractions etc to keep or display. Everything included in editable format, so use as many slides as appropriate for your age group or grade, or change the shapes pages as required. All images ©2015 Colin Billett

A very full set of resources to apply the Pythagorean Theorem to finding the length of a line drawn on a coordinate grid. PowerPoint presentation with early slides reminding learners of the principles and knowledge. Later questions apply the knowledge and lead on to generalizations. Plus extra worksheets on finding perimeter of polygons and finding the area of a circle drawn on a coordinate grid. Surds and use of pi encouraged in line with 2015 UK curriculum. Grade 8 - Understand and apply the Pythagorean Theorem. 8. Apply the Pythagorean Theorem to find the distance between two points in a coordinate system.

Five sets of ten multiple choice questions on number work in PowerPoint; with answers. Topics also included: reviewing.

Algebraic statements in symbols, with with corresponding word descriptions, and representations as areas in the plane, along with function tables. Match up any sets you like - words and symbols seem to go down well, along with the pictorial representation.

A set of cards for talking about algebraic statements. Plus a powerpoint version for discussion, and a powerpoint version with the answers.

Matching cards for statements and answers; with index numbers; parentheses; changed order etc.Plus a PowerPoint of the questions for discussion; plus a PowerPoint of the answers if one runs out of time.

A set of cards for discussion and matching of possibilities, plus a powerpoint of the questions for group reflection, and another powerpoint of some possible answers.

Worksheet/activity to recap simple area, a presentation in PowerPoint to get the learners thinking about volume of cubes, cuboids and prisms, then assorted worksheets presenting prisms in a variety of ways, including those drawn on isometric grids. Common Core Standards Grade 5 upward. In PDF or Word for editing and adopting.

Finding the volume of right rectangular prisms (cuboids in the UK), with a big selection of worksheets, from simple counting of cubes to working backwards from the volume to find other dimensions. Plus harder questions in the style exams. (Worksheets call them cuboids, as in UK maths, but should not be a problem.)

Math Fractions Grade 4. Add and subtract fractions with like denominators. Presentation and lots of activity, and plenty of resources for you to adapt and make your own. Worksheets, fractions cards, all differentiated. Word and PDF - whatever works for you. Makes a colorful and hands-on experience for the students.

Three PowerPoint presentations including multiple choice quiz. Plus two worksheets of exam-style questions.

The motivation for this was the difficulty learners have with measures of centre of grouped data, and no doubt many otherlearners too. I’ve spent years trying to demonstrate the interval in which the median lies, and watched learners who appeared to follow the method for mean of grouped data, only to watch them go to pieces on tests. So this time I went for kinaesthetic and colourful, my main aim always. The documents are in Word so you can cut my photo if you want. I’ve thrown in a couple of real questions, and there are plenty more about, but very easy to make up in this style. All images (c)2015 Colin Billett

A set of great stuff for theoretical and practical lessons on probability. Lots of questions, a PowerPoint introduction that can be fitted in at any time, a quiz that could end one lesson or start another, and events for printing on cards and sorting into order of likelihood. Plus a set of questions for recap and revision. Enough for a couple of lessons, and lots of photographs that will give you and the learners ideas for creating your own questions. All images (c)2015 Colin Billett 'Investigate chance processes and develop, use, and evaluate probability models. Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event. '

Everything you need for a lesson (or two) on creating, reading and interpreting box and whisker plots. Starter activity on PowerPoint to review stem and leaf diagrams; a presentation in PowerPoint on creating, reading and interpreting a box plot with two examples; learner activities, questions in Word or PDF; a plenary presentation in PowerPoint to check learning; and a lesson plan to make the whole thing complete.
