- 1. understand addition and use related vocabulary; recognise that addition can be done in any order; understand subtraction as both 'take away' and 'difference' and use the related vocabulary; recognise that subtraction is the inverse of addition; give the subtraction corresponding to an addition and vice versa; use the symbol '=' to represent equality; solve simple missing number problems [for example, 6 = 2 + ? ]

11 activities/worksheets available - 2. understand multiplication as repeated addition; understand that halving is the inverse of doubling and find one half and one quarter of shapes and small numbers of objects; begin to understand division as grouping (repeated subtraction); use vocabulary associated with multiplication and division Mental methods

6 activities/worksheets available - 3. develop rapid recall of number facts: know addition and subtraction facts to 10 and use these to derive facts with totals to 20, know multiplication facts for the x2 and x10 multiplication tables and derive corresponding division facts, know doubles of numbers to 10 and halves of even numbers to 20

11 activities/worksheets available - 4. develop a range of mental methods for finding, from known facts, those that they cannot recall, including adding 10 to any single-digit number, then adding and subtracting a multiple of 10 to or from a two-digit number; develop a variety of methods for adding and subtracting, including making use of the facts that addition can be done in any order and that subtraction is the inverse of addition

5 activities/worksheets available - 5. carry out simple calculations of the form 40 + 30 = ?, 40 + ? = 100, 56 - ? = 10; record calculations in a number sentence, using the symbols +, -, x , รท and = correctly [for example, 7 + 2 = 9] .

- explain their methods and reasoning when solving problems involving number and data.

- 1. count reliably up to 20 objects at first and recognise that if the objects are rearranged the number stays the same; be familiar with the numbers 11 to 20; gradually extend counting to 100 and beyond Number patterns and sequences
- 2. create and describe number patterns; explore and record patterns related to addition and subtraction, and then patterns of multiples of 2, 5 and 10 explaining the patterns and using them to make predictions; recognise sequences, including odd and even numbers to 30 then beyond; recognise the relationship between halving and doubling The number system
- 3. read and write numbers to 20 at first and then to 100 or beyond; understand and use the vocabulary of comparing and ordering these numbers; recognise that the position of a digit gives its value and know what each digit represents, including zero as a place-holder; order a set of one and two-digit numbers and position them on a number line and hundred-square; round any two-digit number to the nearest 10.

- approach problems involving number, and data presented in a variety of forms, in order to identify what they need to do

3 activities/worksheets available - develop flexible approaches to problem solving and look for ways to overcome difficulties
- make decisions about which operations and problem-solving strategies to use
- organise and check their work

- 1. solve a relevant problem by using simple lists, tables and charts to sort, classify and organise information
- 2. discuss what they have done and explain their results.

- 1. choose sensible calculation methods to solve whole-number problems (including problems involving money or measures), drawing on their understanding of the operations

2 activities/worksheets available - 2. check that their answers are reasonable and explain their methods or reasoning.
