Year 9 - Key Objectives

Number

Make and justify estimates and approximations of calculations
add, subtract, multiply and divide fractions,
Use proportional reasoning to solve a problem, choosing the correct numbers to take as 100%, or as a whole

Algebra

Construct and solve linear equations with integer coefficients (with and without brackets, negative signs anywhere in the equation, positive or negative solution), using an appropriate method
given values for m and c, find the gradient of lines given by equations of the form y = mx + c
Generate terms of a sequence using term-to-term and position-to-term definitions of the sequence, on paper and using ICT
write an expression to describe the nth term of an arithmetic sequence

Shape and Space

Know and use the formulae for the circumference and area of a circle
Solve problems using properties of angles, of parallel and intersecting lines, and of triangles and other polygons
know that the sum of probabilities of all mutually exclusive outcomes is 1 and use this when solving problems

Handling Data

know that the sum of probabilities of all mutually exclusive outcomes is 1 and use this when solving problems
Use cumulative frequency to calculate medians and interquartile range

Using and Applying

Solve substantial problems by breaking them into simpler tasks, using a range of efficient techniques, methods and resources, including ICT
Present a concise, reasoned argument, using symbols, diagrams, graphs and related explanatory text; give solutions to problems to an appropriate degree of accuracy
