# Introduction to Secondary Maths

This is the first unit in the Mr Mathematics long term plan.  The lessons included provide students with an introduction to secondary maths.  They develop their mental arithmetic and written while getting to know their new scientific calculator.  Later on, students develop their problem solving skills with shape and timetables.

This unit takes place in Term 1 of Year 7 and is followed by place value.

##### Prerequisite Knowledge
• Recall multiplication and division facts for multiplication tables up to 12 × 12
• Use place value, known and derived facts to multiply and divide mentally, including: multiplying by 0 and 1; dividing by 1;
• Solve problems involving multiplying and adding
• Compare and classify geometric shapes, including quadrilaterals and triangles, based on their properties and sizes
• identify lines of symmetry in 2-D shapes presented in different orientations

##### Key Concepts
• This unit of work is designed to enable the teacher to assess each student’s baseline knowledge of mathematics.
• Students work in pairs or small groups to solve a range of problem solving activities involving timetables, shape, use of a calculator and place value.
• Encourage students to draw on their prior learning by prompting them to consider place value, the order of operations, and knowledge of timetables, reflective symmetry and properties of 2D shapes.

##### Working mathematically

Develop fluency

• consolidate their numerical and mathematical capability from key stage 2 and extend their understanding of the number system and place value to include decimals, fractions, powers and roots
• select and use appropriate calculation strategies to solve increasingly complex problems
• use algebra to generalise the structure of arithmetic, including to formulate mathematical relationships
• use language and properties precisely to analyse numbers, algebraic expressions, 2-D and 3-D shapes, probability and statistics.

Reason mathematically

• extend their understanding of the number system; make connections between number relationships, and their algebraic and graphical representations
• make and test conjectures about patterns and relationships; look for proofs or counter-examples
• begin to reason deductively in geometry, number and algebra, including using geometrical constructions

Solve problems

• develop their mathematical knowledge, in part through solving problems and evaluating the outcomes, including multi-step problems
• develop their use of formal mathematical knowledge to interpret and solve problems
• begin to model situations mathematically and express the results using a range of formal mathematical representations
• select appropriate concepts, methods and techniques to apply to unfamiliar and non-routine problems

##### Introduction to Secondary MathsSubject Content

Number

• use the concepts and vocabulary of prime numbers, factors (or divisors), multiples
• use the four operations, including formal written methods, applied to integers
• use conventional notation for the priority of operations, including brackets, powers, roots and reciprocals
• use integer powers and associated real roots
• use a calculator and other technologies to calculate results accurately and then interpret them appropriately
• use standard units of mass, length, time, money and other measures

Algebra

• generate terms of a sequence from either a term-to-term or a position-to-term rule

Geometry and measures

• derive and illustrate properties of triangles, quadrilaterals, circles, and other plane figures [for example, equal lengths and angles] using appropriate language and technologies
• identify properties of, and describe the results of, translations, rotations and reflections applied to given figures

#### Mathematics OFSTED Inspection – The Deep Dive

Earlier this week, my school took part in a trial OFSTED inspection as part of getting ready for the new inspection framework in September 2019. This involved three Lead Inspectors visiting our school over the course of two days. The first day involved a ‘deep dive’ by each of the Lead Inspectors into Mathematics, English […]

#### How to Solve Quadratics by Factorising

The method of how to solve quadratics by factorising is now part of the foundational knowledge students aiming for higher exam grades are expected to have.   Here is an example of such a question. Solve x2 + 7x – 18 = 0 In my experience of teaching and marking exam papers students often struggle with […]

#### How Write 3 Part Ratios

When learning how to write 3-part ratios students need to understand how ratios can be made equivalent. The start of the lesson reminds students by asking which of six ratios is the odd one out.  This is presented to the class as they come into the lesson.    Writing Equivalent Ratios  A few students immediately go […]
