First - Number, money and measure

Standard 1.NS.1.2 - Solve subtraction equations involving tens with numbers up to 120

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.
