MATHEMATICS in the New Curriculum Key changes • There is a significant focus on the number strands of the curriculum at both Key Stages. • A new written arithmetic paper is presented at both Key Stages. At Key Stage 2 this replaces the mental arithmetic paper. • There are no extension (L3 or L6) papers at either Key Stage. • Structured apparatus (diennes blocks, numicon, number lines, tracing paper, mirrors) are not permitted in any of the tests. • At Key Stage 2, in the arithmetic test, method marks are available only for use of (short) standard long multiplication and division methods on relevant questions. • Both series of tests are more demanding than previous tests, to match the new higher expectations of the National Curriculum. What are we up against? KS1 •Know division facts for x2 x5 x10 •Find ¼ ½ ¾ ⅓ of a shape and amount. •Solve two step problems using addition and subtraction. •Recognise, write and tell the time to the quarter hour, and begin to tell the time to nearest 5 minutes. KS2 •Place value, comparing, ordering, rounding up to 1,000,000. •Add, subtract, multiply and divide fractions, including those with denominators that share a common factor e.g 4/5 + 3/10. •Find the perimeter of compound shapes. •Algebraic equations. Wicklewood Primary School Calculation Steps & Strategies 2015 •This updated calculation policy is structured in four Stages for staff, children and parents to use as a guide to the ways to calculate using the four operations + - x ÷ from Reception to Yr. 6. •The methods within each Stage are carefully linked to our CLIC calculation challenges which provides a clear progression in number and calculation skills. •The main reason for this update is due to the new calculation expectations for the New National Curriculum 2014. Children are now expected to use column methods. This policy is structured using a progression of three types of column method to support younger children’s knowledge and understanding of the value of number. •1st column method = Wide Column •2nd column method = Long Column •3rd column method = Short Column / Bus Stop •The range of methods within each Stage illustrate an element of choice for the child and recognises that children may have different methods that work best for them. However, by Yr. 6, children are now expected to use the Short Column method to calculate when + - x ÷ •Throughout all the stages of calculation, there should be a focus on ECC Estimate – Calculate - Check •If together we are consistent in the teaching of how to calculate, we will see a clear progression in the methods used throughout the school. This policy will greatly benefit the children as they make their transition between year groups.
