### Analysing Sequences N13

In this resource, from the DfES Standards Unit, students learn to define a sequence using the
general form of the nth term, define a sequence inductively, recognise and define an arithmetic and a geometric progression and to reflect on and discuss these processes. Students should have some understanding of...

### Case Studies

In these Standards Unit: Improving Learning in Mathematics videos you have the opportunity to explore some of the experiences of the teachers and trainers in taking part in the pilot project.

...

### Classifying Shapes SS1

In this resource from the DfE Standards Unit, students learn to name and classify polygons according to their properties, develop mathematical language to describe the similarities and differences between shapes and develop convincing explanations as to why combinations of particular properties are impossible. (...

### Connecting Perpendicular Lines A10

In this resource from the DfE Standards Unit, students will identify perpendicular gradients and lines that are perpendicular, learn to relate their learning about perpendicular lines to their previous learning about straight lines and explain the reasons why lines are parallel and perpendicular. Students should...

### Creating and Solving Equations A2

In this resource from the DfE Standards Unit, students learn to create and solve their own equations, where the unknown appears once. Most students will have been taught rules for solving equations such as ‘change the side, change the sign’ or ‘you always do the same to
both sides’. When used without...

### Creating and Solving Harder Equations A3

In this resource from the DfE Standards Unit, students create and solve their own equations where the unknown appears more than once and learn that there may be more than one way of solving such equations. Before doing this activity students should be able to solve equations where the unknown appears only once....

### Developing an Exam Question: Generalising Patterns A8

In this resource from the DfE Standards Unit, students will learn to: use past examination papers creatively, explore, identify, and use pattern and symmetry in algebraic
contexts, investigate whether a particular case can be generalised further, understand the importance of counter-examples, develop the...

### Developing an Exam Question: Number N10

In this resource from the DfE Standards Unit students learn to use past examination questions creatively by selecting and using appropriate techniques and strategies to solve
problems involving numerical, graphical and algebraic manipulation. Most students will have solved problems such as these...

### Developing an Exam Question: Probability S7

In this resource from the DfE Standards Unit, students use past examination papers creatively, analyse the demands made by examination questions, understand and use estimates or measures of probability from theoretical models, list all outcomes for two successive events in a systematic way and identify mutually...

### Developing an Exam Question: Transformations SS8

In this resource from the DfE Standards Unit, students learn to use past examination papers creatively, recognise and visualise transformations of 2D shapes, transform triangles and other 2D shapes by translation, rotation and reflection and combinations of these. They develop their ability to generalise and...
