 Overview for Y1/2:Y1: relate subtraction totaking away and to counting back.They solve problems,use practical apparatus to model the problem or represent theproblem in a drawing. Later, they count back using a number line,then count back mentally. They explain how they worked out theproblem and record it using the and = symbols. Y2:add or subtractmultiples of 10 by counting in tens, use n square / jottings.Recognise patterns in examples such as90 20 = 70 and 9 7 = 2use knowledge of number bonds to remember sums and differencesof multiples of 10.Children solve word problems usingany one of the four operations.  
 Foundation StageObjectives: Begin to relateaddition to combining two groups of objects and subtraction totaking away In practical activities and discussion begin to usethe vocabulary involved in adding and subtracting Use developingmathematical ideas and methods to solve practical problems  Linked AdultInitiated Play Activities: Play with garage andcars how many on top / bottom, altogether Numbers andoperation signs on magnetic boards. IzzyIsland ICT mathsgames. Play snakes andladders as group with Y1.

(Y2) Ican add and subtract some numbers in my head
 

T u  MO:Count on and back in 10s using IWB bead string.Remind crn that whenwe count on in tens, we are adding 10 each time, and that when wecount back in tens we are subtracting 10. Show this on beadstring. Practicesome 1 digit subtractions with fingers use number fans. Y1 startactivity
