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.

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. Please Rate

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.

This document seeks to draw on evidence informed principles within educational research to establish a framework for effective feedback across all subject areas, in accordance with the findings of the most recent ISI Report (ISI, 2022), in order to improve pupil progress.

The lesson begins with revision of measuring angles before introducing bearings and considering similarities. AfL mini-plenary leads on to 8 examples to complete in books before activity which involves pupils finding bearings to fly on between different cities and potentially discovering reciprocal bearings. Plenary has 5 quick questions and additional challenge questions if required. Please rate.
