This resource is for KS4 students. The resource consists of a lesson presentation and a worksheet. The lesson presentation includes a starter, examples and worked solutions to all the questions on the worksheet. It explains the idea of upper and lower bounds by placing them in the context of taking real-life measurements. Error intervals are also defined and students are shown how to find the maximum possible error. This resource is followed by other lessons: ‘Upper and Lower Bounds with Multiplication’ and ‘Upper and Lower Bounds with Division’.

A battleship type of activity involving paintballing that asks KS3 pupils to test their skill at using positive and negative coordinates. Preferable perhaps to a teacher not wishing to endorse warfare.

A battleship type of activity involving paintballing that asks KS3 pupils to test their skill at using positive coordinates. (There is another free resource for negative and positive coordinates). Preferable perhaps to a teacher not wishing to endorse warfare.

The lesson is aimed at KS4 students, who can plot a linear graph if expressed in the form y = mx + c, but who are slightly baffled by the graph being expressed in the form Ax + By = C.

The resource is for KS3 students and KS4 students taking the Foundation paper. The resource consists of a lesson presentation and structured worksheet. The lesson presentation includes a starter and worked solutions to the worksheet. Students are led through the process of substituting into an algebraic expression, compiling a table and then taking the coordinates from the table to plot the linear graph. This lesson helps students understand that the (x, y) coordinates of a point are written horizontally but are typically compiled vertically in a table.

The lesson is aimed at low ability KS4 students, who struggle to construct or match a graph showing the depth of water against time as water flows at a steady rate into vessels of different shapes. The resource consists of a lesson presentation and a worksheet. The lesson presentation goes through the topic thoroughly. The worksheet gives a summary of the teaching, so that pupils don’t have to copy it down, and three questions. The lesson presentation also has a starter and worked solutions to the questions.

The lesson is aimed at KS4 students who are wondering what relevance different types of graph have. The learning objective is for students to see that these graphs do have real-life meaning and that this helps them differentiate between the different types of graph.

This resource is targeted at low ability KS4 students, who struggle with Pythagoras’ Theorem. They are led through the Theorem in a structured manner, with the learning objective being that they can find both the hypotenuse and one of the shorter sides. The resource consists of a lesson presentation and the structured worksheet.

The resource is aimed at KS3 students, though it would be helpful as revision for low ability GCSE students. Students are given a number of triangles and have to identify whether the largest angle is acute, a right-angle or obtuse and whether the triangle has two or three equal sides. The students cut out the triangles and glue them into the correct part of a grid. This means that every student can have a record of his or her work. The activity ends with some questions as to why certain boxes in the grid must be left empty.

This activity is designed to teach KS3 students the difference between perimeter and area. (Centimetre squared paper is required). The first activity is to find rectangles with the same area but different perimeters. The second activity requires students to find the perimeter and area of a number of composite shapes. Through doing so they should gain an appreciation of the type of shapes that have high perimeter and low area and the types of shapes that have low perimeter and high area.

First few slides are a fun intro. Students are shown the method of dividing the numerator by the denominator to find the first fraction and then dividing the remainder(s) to find the other fractions. The lesson is split into two parts. after each example, there is an exercise consisting of 5 questions.
