Teaching for Mastery
What does Teaching for Mastery mean?
Since the introduction of Mastery in Mathematics, there has been a lot of confusion over what this actually means. Below we have detailed out the basics for you, to help you understand this concept.
Teaching for Mastery means acquiring a deep, long-term, secure and adaptable understanding of the subject. This will allow children to represent a concept in multiple ways, have the mathematical language to explain and be able to apply the concept to new problems and unfamiliar situations. This is achieved through carefully designed lessons which include the ‘5 big ideas’ that underpin TfM.
Some people confuse mastery with Greater Depth. This is not the case, they are two very different things. All lessons allow all pupils to deepen their knowledge and master their learning. Greater Depth refers to pupils who show a greater level of understanding for an area or aspect of learning and are able to challenge themselves further in how they apply and represent the concept.
The 5 Big Ideas
Coherence
Representation and Structure- include mathematical resources

Mathematical Thinking
Fluency
Variation
Conceptual variation
When introducing concepts to children, examples will be carefully selected to include the following:
1. standard representations (a common representation-a and d)
2. non standards representation (an irregular representation which is less common and may challenge the children’s understanding of a concept-c and e)
3. non-concept (A true/false question which pre-empts possible misconceptions-f)
It is important to see concepts in arrange of different representations. This will help them to explain, make connections and see patterns. Some children can find it difficult to visualise concepts. This gives all children an opportunity to use visuals to support their understanding.
Procedural Variation
Within teaching inputs and children’s independent work, numbers and representations will be carefully chosen to draw children’s attention to the learning point.
