These five instant maths ideas explore how decimals can be added and subtracted using a number line A resource sheet for students is included in which they use the box method to multiply decimals. An investigation into the nature of the result when a number is multiplied by a decimal value between zero and one and...

Connect 4: this activity requires students to choose a question and use their skill of adding and subtracting decimals to answer the question. Player one answers their question then finds, and shades in with one colour, the answer on the answer grid. Player two then takes their turn, shading their...

This resource contains four instant maths ideas covering: * the usefulness of a number line when understanding decimals * working out numbers that occur in between two other decimals which can be extended to look at finding values that lie between two fractions by converting to decimals * asking the class to count...

Designed to improve confidence in mathematics, these resources from the Centre for Innovation in Mathematics Teaching, focus on decimals and were developed particularly for primary teachers and those non-specialists who teach mathematics in the lower secondary years....

This SMILE resource contains two packs of games, investigations, worksheets and practical activities supporting the teaching and learning of decimals, from reading decimals from a scale to multiplying two decimal numbers without a calculator.

Decimals pack one contains fifteen work cards...

This resource consists of thirteen work cards each requiring students to investigate some aspect of the use of decimals. Associated with each card is a student help sheet and comprehensive teacher notes detailing assumed knowledge for each task, the purpose of the...

From the Nuffield Foundation, this module focuses on the use of decimals in multiplication and division and then on applications which include averages, speed calculations and rounding.

The resource consists of:

This resource, from the Centre for Innovation in Mathematics Teaching, explores the misconception that decimals and fractions are different types of numbers. It illustrates how to write a decimal value as a fraction, as well as how, by using division, most fractions can be expressed with denominators of 10, 100 or...

Operational Research (O.R.) is the discipline of applying advanced analytical methods to help make better decisions. The O.R. approach often involves constructing and using mathematical models and problem structuring methods to represent the wide range of problems faced by organisations. The results of these models...

This collection of Nuffield Maths resources explores Decision maths. The demand is roughly equivalent to that in GCE A level.

This computing resource for primary schools introduces the concept of decomposition through dance. Using combinations of hand-jive, clapping or tutting, the lesson demonstrates how complex sequences of instructions (algorithms) can be broken down into smaller chunks. The children are challenged to look for patterns...

The net for a cube is shown. The each face of the cube has a different design. Four pictures of the cube are shown but one of the faces has been left blank. The challenge is to find out which design should be drawn on the blank face. This resource would be useful as an extension when teaching nets of cubes.

This resource, provided by Anne Watson, Els De Geest and Stephanie Prestage, describes how a group of ten teachers taught low attaining groups in secondary school, and what features were seen to be important. The teachers had a shared commitment to improving the attainment of their lowest attaining students by...
