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. (...

Understanding Perimeter and Area SS2

In this DfE Standards Unit resource, students learn to understand the difference between perimeter and area. Students get practice in calculating the areas and the perimeters of rectangular shapes. Students may have had some previous experience of calculating perimeter and area. (GCSE Grades D - G)

Dissecting a Square SS3

In this resource from the DfE Standards Unit, students learn to express a part or whole diagram in fractions or percentages, convert a fraction to a percentage (using a calculator), calculate areas of rectangles, triangles, circles and parts of circles and add, subtract and multiply fractions. This session builds...

Evaluating Statements about Length and Area SS4

In this resource from the DfE Standards Unit, students learn to understand concepts of length and area in more depth, revise the names of plane shapes, develop reasoning through considering areas of plane compound shapes and construct their own examples and counter-examples to help justify or refute conjectures....

Evaluating Statements about Enlargements SS5

In this DfE Standards Unit resource, students explore the relationship between linear and area enlargement, substitute into algebraic statements and discuss some common misconceptions about enlargement. Students will have covered some aspects of enlarging shapes before, but they may not have explored the...

Representing 3D Shapes SS6

In this resource from the DfE Standards Unit, students interpret 2D representations of 3D shapes, analyse 3D shapes using plans, elevations, and isometric drawings and develop their reasoning ability in spatial contexts. Many students may have met these ideas before, but they may still experience difficulties in...

Transforming Shapes SS7

In this DfE Standards Unit resource, students learn to recognise and visualise transformations of 2D shapes and translate, rotate, reflect and combine these transformations. Students unfamiliar with the terms ‘rotation’, ‘reflection’ and ‘translation’ will need some introduction to these. The session also assumes...

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...

Evaluating Probability Statements S2

In this resource from the DfE Standards Unit, students discuss and clarify some common misconceptions about probability. This involves discussing the concepts of equally likely events, randomness and sample sizes. They will also learn to reason and explain. This session assumes that learners have encountered...

Ordering Probabilities S1

In this DfE Standards Unit resource, students learn to understand that probabilities are assigned values between 0 and 1. They will on an decide an appropriate value for the probability of a given event and use some of the vocabulary associated with probability such as
‘certain’, ‘impossible’, ‘likely’. They...
