Outcomes
MA2-RN-01 applies an understanding of place value and the role of zero to represent numbers to at least tens of thousandsMA2-RN-02 represents and compares decimals up to 2 decimal places using place valueContent dot points
Each dot point has its own page with resources matched to it.
Whole numbers: Order numbers in the thousands
- Arrange numbers in the thousands in ascending and descending order
- Recognise and describe how rearranging digits changes the size of a number (Reasons about relations)
- Identify the nearest thousand, 10 thousand or 100 thousand to numbers
Whole numbers: Apply place value to partition, regroup and rename numbers up to 6 digits
- Name thousands using the place value grouping of ones, tens and hundreds of thousands
- Use place value to expand the number notation
- Partition numbers of up to 6 digits in non-standard forms
Whole numbers: Recognise and represent numbers that are 10, 100 or 1000 times as large
- Recognise the number of tens, hundreds or thousands in a number
- Describe how making a number 10, 100 or 1000 times as large changes the place value of digits
Decimals: Extend the application of the place value system from whole numbers to tenths and hundredths
- Divide a length representing one whole into 10 equal parts and label the divisions using decimal notation
- Use the decimal point as a marker to identify the position of the ones digit when expressing tenths as decimals
- Recognise that 10-tenths is recorded as 1.0 and regroup when using decimal notation
- Represent and compare tenths as decimals using linear representations (Reasons about relations)
- Subdivide tenths into 10 equal parts and record hundredths using place value
- Express decimals as both tenths and hundredths
- Locate and order decimals representing tenths and hundredths on a number line, describing their relative size
- Interpret zero digits at the end of a decimal
- Distinguish between the role of zero in various positions
Decimals: Make connections between fractions and decimal notation
- Record equivalent measurements using decimals
- Connect fraction strips showing tenths to a number line marked in hundredths
- Compare and order decimals of up to 2 decimal places
- Make connections between fractions and decimal notation for key benchmark values (Reasons about relations)
