#### PSHE Stimuli for discussion topics

(3)
Extensive list of links to articles and videos that can be used as stimuli for discussion topics during tutor time or as part of the PSHE curriculum. Essential for PSHE coordinators, Heads of Year and Form Tutors. PLEASE REVIEW.

#### Calculus: Optimisation

(1)
The presentation begins with a review of quadratics and presents students with an optimisation question which they are expected to solve using quadratics. The concept of optimisation is then explored in more detail by asking students to find the maximum volume that can be made from a 12cm x 12cm square (in the context of for instance minimising production costs). This site provides a useful platform through which to launch into a discussion about finding the maximum volume. There are then a selection of questions which I printed out and placed around the room for students to tackle, in pairs. For the plenary, the students are presented with a similar (but note not identical) problem to the one at the start of the lesson and are asked to solve using calculus before checking their answer using quadratics. Please Review

#### Multiplying and Dividing by Powers of 10

(17)
Introduction to multiplying & dividing by powers of 10. Starter consolidates prior learning of multiplying/ dividing by multiples of 10. Lesson then facilitates pupils understanding of link between multiplying/ dividing by multiples of 10 and powers of 10. Additional question can be generated using question generator from bowenr. Consolidation is through mini plenary of 5 quick questions before main activity of completing a circuit of questions which require pupils to establish fill in the blanks. Extenstion questions take this further. 5 quick questions plenary at the end. Please Rate.

#### Introduction to Distance-Time Graphs

(50)
Introduction to Distance-Time graph which starts with exercise on finding the gradient of lines (on a Distance-Time graph). It then leads on to a collective memory task to discover the key features of a Distance-Time graph. After a couple of worked examples, progress can be tracked through a mini-plenary which leads into a matching activity (find correct description for each graph). The lesson is rounded off with 5 quick questions. Please Rate.

#### Reading exam instructions: 3 minute test

(1)
Ideal starter/ plenary to emphasise the importance of following exam instruction carefully.

#### Mathematics in Computer Science: Binary coding

(8)
This lesson serves as an introduction to the role of mathematics in computer science by looking at binary coding. It begins with a guess my number magic trick grounded in binary before exploring binary coding through a series of activites, games and codes. Worksheet and conversion tables included. Resources adapted from gedlad and hannahskellan. Please rate.

#### Cryptic Inequalities

(11)
STARTER: Solve & represent simple inequalities on line. (Hint card included)\n\nMINI-PLENARY: Representing solutions\n\nACTIVITY: Pupils solve inequalities and find matching solution. When all pairs correctly matched flip cards over (print Linear Inequalities Mixed2.fjsw double sided) to reveal additional questions.\n\n&gt;&gt;&gt;EXT take the first letter of the number in the answer in these additional questions and use the Matching Activity Decoder.docx to decode these letters which gives a 9 letter anagram to crack.\n\nMWB plenary with range of difficulty.\n\nPlease Rate

#### Introduction to Sequences

(12)
Starter on hand out (included). Discussion of what sequences are builds to term-to-term rule. Pupils required to find next to terms for sequences and add answers together to generate 3 digit code to unlock combination lock. Moves on to dominoes activity which develops understanding of position-to-term rule. Plenary with questions of varying difficulty.\nPlease Rate

#### 3D Coordinates

(31)
Building on prior knowledge of finding the midpoint in 2D, this lesson is on finding the coordinates of any point in 3D with more able pupils progressing on to finding the midpoint in 3D. Resources adapted from Psholl, Jmillsdadson, Ben Cooper and NCETM. Includes starter (print double sided),hint sheet), rich activity, 3D grid templates and extension questions. Please Rate

#### MOBIUS STRIP: A GENERAL MATHS QR HUNT

(1)
A challenging maths quiz comprised of 11 questions which pupils have to find & generate from QR codes. It covers a variety of topics including quadratic equation, algebra and history of mathematics. Pupils who correctly answer all questions receive a message which explains they have to take the first letter from each answer é use it to generate the name of a mathematical shape. If they do this correctly they should find the term Mobius Strip then construct in order to receive a prize. PLEASE REVIEW

(3)
Research Project on Student Leadership. Leader begins as deputy supporting Leader & learning roles é responsibilities (A). Progress to Leader the following week é have to make a presentation to the class on maths in the real world. They also nominate other pupils as all stars (D) é receive the attached feedback report (B) in the post upon completion. After all pupils have completed a week a single pupil is elected as Leader and assumes more responsibility including some teaching (E). Feedback so far has been positive from pupils, parents and staff. Please rate.

#### OPERATION ULTRA: GCHQ Codebreaking Project
