This resource features a task that involves interpreting functions that arise in practical situations.

Students are given the task of matching together worded descriptions, functions, and graphs. An example of a worded situations is a movie subscription where you get two movies free, but then you get charged...

This resource develops the concept of representing inequalities on a Cartesian coordinate grid. Students work with algebraic representations in a variety of formats and then shade the relevant areas.

An initial activity is to play a game ‘Hunting the target’. This involves students being given inequalities...

This is a problem solving lesson, intended to assess how well students are able to:

• Understand and calculate the conditional probability of an event A, given an event B
• Represent events as a subset of a sample space using tables, tree diagrams, and Venn diagrams

The problem is...

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...

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...

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...

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...

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...

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...

Carom Maths provides this resource for teachers and students of A Level mathematics.

A repunit, which stands for repeated unit, is a number like 11, 111, or 1111 that contains only the digit 1 and extends to number bases other than base ten. This presentation challenges students to prove that any repunit...

This Powerpoint was presented at...

Students are asked to design and make an acrylic fridge magnet that would remind a specific type of user to recycle the waste produced within their kitchen at home. To begin students are asked to identify some typical workshop tools, to embed the task within the resistant materials area of design & technology....

This STEM activity teaches learners about the reflection of light in a mirror, by giving pupils the opportunity to use reverse writing to see how words change when reflected in a mirror and then make notes on this. This activity could be used as a starter or main activity to introduce concepts of light and build on...

This activity aimed at primary learners, looks at the properties and uses of materials and what humans need to stay alive. It introduces Ricky who is going on an expedition to Antarctica and asks children to decide what he needs to take with him. By making comparisons, sorting and grouping objects and using their...

This resource, from Siemens, looks at the function of a wheel bearing on trains and the importance of finding out whether replacement is needed. Students consider the cost implications of replacing bearings before it is necessary and the cost and safety implications of not replacing them in time. Traditionally,...
