# Compound Measures

## 3 files14/06/2016

(Used for Tiffin Year 8 scheme of work)

(a) Solve simple problems involving (average) speed, distance and time.

(b) Solve problems involving density, mass and volume (which could include volumes of prisms and cuboids).

(c) Solve more complex problems involving speed, distance and time, including with multiple phases of a journey, or an algebraic element.# GCSE Counting Strategies

## 3 files20/03/2017

Counting by (a) systematic listing and (b) by multiplying. Part of the new GCSE specification.

# Probability (pre-GCSE)

## 8 files11/05/2016

(Used for the Tiffin Year 8 scheme of work)

(a) Determine probabilities using matching outcomes/total outcomes.

(b) Understand the concept of a 'sample space'. Identify the sample space for both a single event and two combined events (e.g. adding two dice) and use to calculate probabilities.

(c) Understand the difference between experimental and theoretical probabilities. Calculate experimental probabilities/relative frequencies and estimate the most likely count given the number of trials and a probability.# Robot Path Activity

## 2 files11/05/2016

Activity in which students have to count the total number of possible paths for a robot given certain restrictions on its movements, in order to work out probabilities.

# Bounds (pre-GCSE)

## 2 files11/05/2016

(Used for Tiffin Year 8 scheme of work)

Identify upper and lower bounds for a measurement to a given degree of accuracy, both with decimal places and significant figures (subsequent calculations involving bounds are not required).
