# Direct & Indirect Proportion (GCSE)

## 3 files01/02/2019

Covers the GCSE specification (including graphs of direct and inverse proportion).

# GCSE Ratio

## 3 files29/12/2018

Covers all aspects of the GCSE 2017+ specification, including simplifying ratios, ratio problems where the total, difference or one of the parts is given, subdividing ratios, combining ratios, and problems involving changing ratios.

# Full Coverage: Ratio

## 1 files25/02/2018

GCSE question compilation which aims to cover all types of questions that might be seen on the topic of ratio. Students can complete this set of questions interactively on the DFM Homework Platform. Also contains answers.

# Full Coverage: Direct & Inverse Proportion

## 1 files23/01/2018

GCSE question compilation which aims to cover all types of questions that might be seen on the topic of indirect and inverse/indirect proportion. Students can complete this set of questions interactively on the DFM Homework Platform. Also contains answers.

# Ratio & Map Scale

## 4 files18/05/2016

Used for the Tiffin Year 7 scheme of work. Includes a number of UKMT problems.

# Sherlocked - Ratio

## 1 files13/05/2016

A variety of puzzles. Allows students to select questions. Perfect for interactive whiteboards.

# Ratio & Proportion (Pre-GCSE)

## 4 files12/05/2016

(Used for Tiffin Year 9 scheme of work)

(a) Methods for solving problems involving direct and indirect proportion, including the unitary method (but not quadratic/cubic/root relationships).

(b) Problems involving ratio.

(c) Extension: 3 way relationships, e.g. "If it takes a men b hours to dig c holes..."

This (intentionally) does not make reference to the GCSE method of establishing the constant of proportionality.
