Representing quadratic functions graphically

This resource develops the concept of what the different algebraic forms of a quadratic function reveal about the properties of its graphical representation. Particular attention is paid to:

• How the factored form of the function can identify a graph’s roots.
• How the completed square form of...

Representing Reactions

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Interpret the meaning of the symbols + and → in a word equation.

• Select the word equation that correctly represents the chemical reaction described.

• ...

Representing the laws of arithmetic

This lesson develops the concept of using diagrammatic representations of calculations. Attention is paid to order of operations, along with the distributive and commutative properties.

An introductory activity considers areas of rectangles in relation to calculations, what is often termed ‘the grid method...

Representing trigonometric functions

This lesson develops the concept of using trigonometry to model a real-world situation. In particular students will:

• Model a periodic situation, the hight of a person on a Ferris wheel using trigonometric functions
• Interpret the constants a, b, c in the formula h = a + b cos ct in terms of the...

Representing variability with mean, median, mode and range

This is a concept development lesson that involves deepening understanding of how to calculate the mean, median, mode, and range from a frequency chart. Coverage is also given to using a frequency chart to describe a possible data set given information on the mean, median, mode and range.

The situation is...

Representing: road race

This problem solving resource is intended to help students with recognizing and using proportional relationships, including through the use of graphs

Students are given information about a road race. They are presented with a map and information about the speeds of two runners. The race consists of four laps...

Each book in this series, aimed at 9-11 year olds, explains how the body's systems function and how to stay fit and healthy. 'Case Notes' panels appear on some pages providing answers to popular questions about the body. This book focuses on reproduction and growth.

Reproduction and Life Cycles - Part 1

Aimed at primary level, this resource looks at parts of a flower and the role they play in reproduction. A range of activities are provided which build on their understanding of the parts of a plant. These include: a dissection of a flower to see its parts – the sepals, petals, stamens and stigma, style and ovary,...

Reproduction and Life Cycles - Part 2

Aimed at primary level, this resource looks at pollination, fertilisation, fruit formation and seed dispersal. It includes activities in which children observe the different types of fruits and their means of dispersal and develop an understanding of their importance in...
