Addition methods Myles Gresswell, Queen Anne First School

Addition - Reception 1. Record the outcome when two groups of objects are combined into one group Record the outcome of physically moving along the number track “Standing on 3 and moving forwards two spaces” 3 5 = = 5+ Myles Gresswell, Queen Anne First School

Addition – Year 1 1. Combining sets to make a total 2. Counting along a number track, then number line in 1s and 10s 5 and 1 more is ? 5 and 2 more is ? 5 and 3 more is ? 6 6,7 6, 7, Count on one, two, three 3. Number bonds to Number bonds to 5, 6, 7, 8, 9 Myles Gresswell, Queen Anne First School

Addition – Year 2 1. Counting on in 10s then 1s on a number square and number line = Number bonds to 10 and Number bonds to 11, 12, 13, 14, 15, 16, 17, 18 and 19 Myles Gresswell, Queen Anne First School

1. Use a number line Start from the largest number, partition the second and add the most significant digit first = Addition – Year Partition both numbers and add the tens, then the units, finally recombining = ( ) + (6 + 7) = = Expanded vertical layout, adding the tens first ( ) (6 + 7) Myles Gresswell, Queen Anne First School

1. Use a number line, partitioning and adding the hundreds first = Addition – Year Expanded vertical layout, adding the hundreds first Leading to expanded vertical layout adding the units first Myles Gresswell, Queen Anne First School

Addition – Year 5 2. Leading to compact vertical method with carrying figures below the line 1. Expanded vertical layout, adding the units first Compact vertical calculations with two and then several numbers and decimals in a money context (Go back to expanded layout if necessary) £ £ £ £ Remember to still give the digits their correct place value names eg = 1300 Myles Gresswell, Queen Anne First School

Addition – Year 6 1. Compact vertical layout Compact vertical layout with decimals requiring zero placeholders to be inserted When returning to a written calculation at this stage, e.g. to revise or to extend to decimals or to numbers with more digits, it is a good idea to start again with informal, expanded methods. This helps to retain their understanding of the link between different methods and makes it easier for them to resort to the expanded method if they need to. 0 Myles Gresswell, Queen Anne First School
