Here is some revision help for chapters 1-4.

Firstly click here for a copy of the level 5 to 6 descriptors like you have used in lesson.

You need to revise:

Arithmetic with integers	Order decimals
	Add, subtract, multiply and divide integers
	Order, add, subtract, multiply and divide negative numbers
Factors and primes	Use multiples, factors, common factors, highest common factors, lowest common multiples and primes
Prime factor decomposition	Use a factor tree to find the product of primes, e.g. 8000 = 26 × 53
LCM and HCF	Use multiples, factors, common factors, highest common factors, lowest common multiples and primes
Square roots and cube roots	Use squares, square roots, cubes and cube roots.
Metric measure	Choose and use units of measurement to measure, estimate, calculate and solve problems in a range of contexts
Imperial measure	Know rough metric equivalents of imperial measures in common use, such as miles, pounds (lb) and pints

Area of a parallelogram and trapezium	be able to find the area of parallelogram and trapezium
	Calculate areas of compound shapes
Two or more events	use diagrams and tables to record in a systematic way all possible mutually exclusive outcomes for single events and for two successive events
	Use tree diagrams and sample space diagrams
Tree diagrams	use diagrams and tables to record in a systematic way all possible mutually exclusive outcomes for single events and for two successive events
Experimental probability	Compare estimated experimental probabilities with theoretical probabilities, recognising that: – if an experiment is repeated the outcome may, and usually will, be different
Comparing experimental and theoretical probability	– increasing the number of times an experiment is repeated generally leads to better estimates of probability
Fractions and decimals	Order decimals, and know how to convert between fractions and decimals to order fractions
Adding and subtracting fractions	Add and subtract fractions by writing them with a common denominator
Multiplying and dividing fractions	Multiply and divide fractions
Percentage problems	Calculate percentages and find the outcome of a given percentage increase or decrease
Fractions, decimals and percentages	Order fractions by writing them with a common denominator or by converting them to decimals
	Express one given number as a percentage of another
