Standard 2.NS.1.2 - Solve subtraction equations to find the missing digit.

Included Skills:

Number and number processes
• I have extended the range of whole numbers I can work with and having explored how decimal fractions are constructed, can explain the link between a digit, its place and its value.
• Having determined which calculations are needed, I can solve problems involving whole numbers using a range of methods, sharing my approaches and solutions with others.
• I have explored the contexts in which problems involving decimal fractions occur and can solve related problems using a variety of methods.
• Having explored the need for rules for the order of operations in number calculations, I can apply them correctly when solving simple problems.
• I can show my understanding of how the number line extends to include numbers less than zero and have investigated how these numbers occur and are used.
• Reads, writes and orders whole numbers to 1 000 000, starting from any number in the sequence.
• Explains the link between a digit, its place and its value for whole numbers to 1 000 000.
• Reads, writes and orders sets of decimal fractions to three decimal places.
• Explains the link between a digit, its place and its value for numbers to three decimal places.
• Partitions a wide range of whole numbers and decimal fractions to three decimal places, for example, 3?6 = 3 ones and 6 tenths = 36 tenths.
• Adds and subtracts multiples of 10, 100 and 1000 to and from whole numbers and decimal fractions to two decimal places.
• Adds and subtracts whole numbers and decimal fractions to two decimal places, within the number range 0 to 1 000 000.
• Uses multiplication and division facts to the 10th multiplication table.
• Multiplies and divides whole numbers by multiples of 10, 100 and 1000.
• Multiplies and divides decimal fractions to two decimal places by 10, 100 and 1000.
• Multiplies whole numbers by two digit numbers.
• Multiplies decimal fractions to two decimal places by a single digit.
• Divides whole numbers and decimal fractions to two decimal places, by a single digit, including answers expressed as decimal fractions, for example, 43 ÷ 5 = 8?6.
• Applies the correct order of operations in number calculations when solving multi-step problems.
• Identifies familiar contexts in which negative numbers are used.
• Orders numbers less than zero and locates them on a number line.
