Included Skills:

Number and number processes
I have investigated how whole numbers are constructed, can understand the importance of zero within the system and can use my knowledge to explain the link between a digit, its place and its value.
I can use addition, subtraction, multiplication and division when solving problems, making best use of the mental strategies and written skills I have developed.
Reads, writes, orders and recites whole numbers to 1000, starting from any number in the sequence.
Demonstrates understanding of zero as a placeholder in whole numbers to 1000.
Uses correct mathematical vocabulary when discussing the four operations including, subtract, add, sum of, total, multiply, product, divide and shared equally.
Identifies the value of each digit in a whole number with three digits, for example, 867 = 800 + 60 + 7.
Counts forwards and backwards in 2s, 5s, 10s and 100s.
Demonstrates understanding of the commutative law, for example, 6 + 3 = 3 + 6 or 2 Ã— 4 = 4 Ã— 2.
Applies strategies to determine multiplication facts, for example, repeated addition, grouping, arrays and multiplication facts.
Solves addition and subtraction problems with three digit whole numbers.
Adds and subtracts multiples of 10 or 100 to or from any whole number to 1000.
Applies strategies to determine division facts, for example, repeated subtraction, equal groups, sharing equally, arrays and multiplication facts.
Uses multiplication and division facts to solve problems within the number range 0 to 1000.
Multiplies and divides whole numbers by 10 and 100 (whole number answers only).
Applies knowledge of inverse operations (addition and subtraction; multiplication and division).
Solves two step problems.
