• I can recognise the place value of each digit in a 3-digit number.
• I can identify, represent and estimate numbers using different representations.
• I can solve number problems and practical problems using above.

Calculations

I can add and subtract mentally, including:

• A 3-digit number and ones
• A 3-digit number and tens
• A 3-digit number and hundreds
• I can add and subtract numbers with up to three digits, using formal written methods of columnar addition and subtraction.
• I can estimate the answer to a calculation and use inverse operation to check answers.
• I can solve problems, including missing number problems, using number facts, place value, and more complex addition and subtraction.
• I can recall and use multiplication and division facts for the 3, 4 and 8x tables.
• I can write and calculate mathematical statements for multiplication and division using the multiplication tables, including for 2-digit numbers, using mental and progressing to formal written methods.
• I can solve problems, including missing number problems, involving multiplication and division, including integer scaling problems and correspondence problems in which n objects are connected to m objects.

Fractions, decimals and percentages

• I can count up and down in tenths.
• I recognise that tenths arise from dividing an object into 10 equal parts and in dividing 1-digit numbers or quantities by 10.
• I recognise and can find and write factions of a discrete set of objects: unit fractions and non-unit fractions with small denominators.
• I can compare and order unit fractions and factions with the same denominators.
• I can add and subtract factions with the same denominator within one whole.
• I can solve problems involving the above.
