#### United Kingdom – National Curriculum expand/collapse

• ##### KS1.Ma2 – Number
• Knowledge, skills and understanding

• Using and applying number

• KS1.Ma2.1 – Pupils should be taught to:

• Problem solving

• KS1.Ma2.1.a – Approach problems involving number, and data presented in a variety of forms, in order to identify what they need to do

• Numbers and the number system

• KS1.Ma2.2 – Pupils should be taught to:

• Counting

• KS1.Ma2.2.a – 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

• The number system

• KS1.Ma2.2.c – 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.

#### Australia – Australian Curriculum expand/collapse

• ##### Number and Algebra
• Number and place value

• ACMNA013 – Recognise, model, read, write and order numbers to at least 100. Locate these numbers on a number line

• ACMNA015 – Represent and solve simple addition and subtraction problems using a range of strategies including counting on, partitioning and rearranging parts

#### New Zealand – National Standards expand/collapse

• ##### 2.NA – Number and algebra
• 2.NA.1 – Apply counting-on, counting-back, skip-counting, and simple grouping strategies to combine or partition whole numbers

#### United States – Common Core State Standards expand/collapse

• ##### K.OA – Operations & Algebraic Thinking
• Mathematics

• K.OA.1 – Represent addition and subtraction with objects, fingers, mental images, drawings (Drawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.)), sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

• ##### 1.OA – Operations & Algebraic Thinking
• Mathematics

• 1.OA.5 – Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
