6: Continue to practice previous skills. Count forwards and backwards in simple fractions, decimals and percentages. Bridging through decimals, i.e. 1.5 – 0.8 = 1.5 – 0.5 then -0.3 using empty number line. Ensure all children are confident recalling basic facts to 20 and deriving using place value. Make links between decimals, fractions and percentages. Second stage of column method: The concept of exchange is introduced through continued use of practical equipment (manipulatives). Teachers model: “I have seven tens and two ones. I need to subtract four tens and seven ones.” “At the moment, I cannot subtract seven ones from two ones, so I need to transfer one ten to become ten ones.” “Now I can take away seven ones Formal columnar:
