A complete lesson on prime factors. Intended as a challenging task to come after pupils are familiar with the process of expressing a number as a product of prime factors (see my other resources for a lesson on this). Activities included: Starter: Questions to test pupils can list all factors of a number using factor pairs. Main: Pupils find all factors of a number using a different method - by starting with the prime factor form of a number and considering how these can be combined into factor pairs. Links well to the skill of testing combinations that is in the new GCSE specification. Possible extension of pupils investigating what determines how many factors a number has. Plenary: A look at why numbers that are products of three different primes must have 8 factors. No worksheets required and answers included throughout.

A complete lesson on prime factors, but not the usual questions. Intended as a challenging task to come after pupils are familiar with the process of expressing a number as a product of prime factors (see my other resources for a lesson on this). Activities included: Starter: A nice ‘puzzle’ where pupils work out three seemingly unrelated multiplication sums (a good chance to practice another non-calculator skill), only to find they give the same answer. Intended to stimulate some discussion about prime factors. Main: Four mini-activities, where pupils use one number’s prime factor form to obtain the prime factor form of some related numbers. An opportunity for pupils to be creative and come up with their own puzzles. Plenary: A final puzzle to check pupils’ understanding of the key idea of the lesson. Printable worksheets and answers included. Please review it if you buy as any feedback is appreciated!

A complete lesson for first teaching pupils how to express a number as a product of its prime factors using a factor tree. Activities included: Starter: Three puzzles relating to prime numbers, intended to increase pupils’ familiarity with them. Main: Examples and questions (with a progression of difficulty and some intrigue). Plenary A ‘spot the mistake’ question. No worksheets required and answers included throughout. Please review it if you buy as any feedback is appreciated!

The last of five complete lessons on linear sequences. Looks at patterns of squares or lines that each form a linear sequence. Adapted from a resource by another TES user called flibit (who has made some excellent resources). Printable worksheets included.

A complete lesson for first teaching pupils how to find the nth term rule of a linear sequence. Activities included: Starter: Questions on one-step linear equations (which pupils will need to solve later). Main: Examples and quick questions for pupils to try and receive feedback. A set of questions with a progression in difficulty, from increasing to decreasing sequences, for pupils to practice independently. Plenary: A proof of why the method for finding the nth term rule works. Answers provided throughout. Please review it if you buy as any feedback is appreciated!

A complete lesson on finding a term given its a position and vice-versa. Activities included: Starter: Recap questions on using an nth term rule to generate the first few terms in a linear sequence. Main: Short, simple task of using an nth term rule to find a term given its position. Harder task where pupils find the position of a given term, by solving a linear equation. Plenary: A question to get pupils thinking about how they could prove if a number was a term in a sequence. No worksheets required, and answers are included. Please review it if you buy as any feedback is appreciated!

A complete lesson on using an nth term rule of a linear sequence to generate the first 5 terms in the sequence. Activities included: Starter: Questions to check pupils can evaluate simple algebraic expressions. Main: Introduction to the idea of an nth term rule. Example-question pairs, giving pupils a quick opportunity to try to generate sequences and receive feedback. A set of questions on generating the first 5 terms of increasing sequences, with a progression in difficulty and an extension task. A similar task for decreasing sequences. Plenary: A ‘spot the mistake’ question. Printable worksheets and answers included. Please review it if you buy as any feedback is appreciated!

A complete lesson on defining, recognising and extending linear sequences. Activities included: Starter: Pupils discuss whether six sets of numbers are sequences, and if so, what the rules are. Main: Slides to define linear sequences, followed by mini whiteboard questions and a worksheet of extending linear sequences. A fun puzzle a bit like a word search (but where you try to find linear sequences). Plenary: Another nice puzzle where pupils try to form as many linear sequences as they can from a set of numbers. Printable worksheets and answers included. Please review it if you buy as any feedback is appreciated!

A complete lesson on subtracting a negative number. Activities included: Starter: Some recap questions on adding a negative number (I always teach this first). Main: A slide showing a number pattern to demonstrate the logic of subtracting a negative. Example question pairs with number lines, for pupils to practice and give a chance to provide instant feedback. A set of differentiated questions. A more challenging task for pupils to discuss in pairs, where they try to find examples or counterexamples for different scenarios. Plenary: A deceptively simple puzzle to consolidate the key point of the lesson. Printable worksheets and answers included. Please review it if you buy as any feedback is appreciated!

A complete lesson on adding a negative number. Activities included: Starter: Some questions on number bonds. Main: A slide showing a number pattern to demonstrate the logic of adding a negative.

A complete lesson for introducing mean, median and mode for a list of data. Activities included: Mini whiteboard questions to check pupil understanding of the basic methods. A worksheet of straight forward questions. Mini whiteboard questions with a progression in difficulty, to build up the skills required to do some problem solving... A worksheet of more challenging questions, where pupils are given some of the averages of a set of data, and they have to work out what the raw data is. Some final questions to stimulate discussion about the relative merits of each average. Printable worksheets and answers included. Please review it if you buy as any feedback is appreciated!

A short investigation based on a lovely puzzle I saw a while ago. Requires only knowledge of square numbers to investigate and enjoy, but pupils will need to be able to expand double brackets to understand a proof of the puzzle. Could be used with any age!

Inspired by something similar I saw on Don Steward's Median blog, a set of non-calculator questions that reward pupils for applying the basic index laws before trying to work out the answer.

Two activities finding missing angles, one using rules for parallel lines and the other using circle theorems. The intention is that pupils are presented with step-by-step solutions in the form of a cartoon strip, and have to identify the rule used to do each step of the solution.

A powerpoint with worksheets on the profit parabola model. A nice rich task to use with high-ability GCSE students, to deepen their understanding of quadratic functions/maximum points and also to see a real-life application of maths.
