Conservation

In this resource from Defence Dynamics, students are set a mystery to solve in small groups which considers the impacts of human activity on the environment.

Salisbury Plain is a military training area, yet it contains a site of special scientific interest (SSSI) and is home to a wide range of species...

Straight Line Graphs Mystery

This resource created by Shirley Fall has twenty mystery fact cards, each containing a statement about the features of straight line graphs and how they lie on a 3 by 3 grid. The rationale is for students to use the fact cards to discover the features of each graph - its gradient, its intercept, its graph and...

Ordering Fractions and Decimals N1

In this resource from the DfE Standards Unit, students learn to interpret decimals and fractions using scales and areas, find equivalent fractions, order and relate fractions and decimals and to reflect on and discuss these processes. Students will have met these concepts before. Many, however, may still have...

Evaluating Statements about Number Operations N2

In this resource from the DfE Standards Unit, students learn to understand the properties of number operations, substitute integers, fractions, decimals and negative numbers into statements and equations in order to test their validity and address common misconceptions about the effect of addition, subtraction,...

Rounding Numbers N3

In this resource from the DfE Standards Unit, students work together to round numbers to the nearest 10, 100, 1000. They make generalisations from the results obtained. Students should have some awareness of place value. (GCSE grades E-G)

Estimating Length Using Standard Form N4

In this resource from the DfE Standards Unit, students learn to interpret decimals using metric units, estimate lengths of real life objects and interpret standard form.They will also discuss and understand these processes. Some students will have encountered decimals and standard form before. The opening...

Understanding the Laws of Arithmetic N5

In this resource from the DfE Standards Unit, students learn to interpret numerical expressions using words and area representations, recognise the order of operations and equivalent expressions and understand the distributive laws of multiplication and division
over addition (the expansion of brackets). Most...

Wider Implications of Shopping

Produced by the Royal Academy of Engineering (RAE) this activity aims to encourage students to consider the wider environmental, social and economic implications of shopping. It can be conducted in small groups as an introduction to sustainability.

Evaluating Directed Number Statements N9

In this resource from the DfE Standards Unit students learn to make valid generalisations about the effect of operations on directed numbers. It is helpful if students have already attempted to use directed quantities in contexts (e.g. money or temperature) before
attempting this session. In this session,...

Using Directed Numbers in Context N8

In this resource from the DfE Standards Unit students learn to understand and use directed numbers in the context of temperatures. This session requires no prior knowledge.Students are provided with the temperatures in four cities, temperature differences between these and four other cities are also given. Students...
