Why this why now
Students up to this point have been working with integer values and have had few opportunities to work explicitly on estimation. We are starting the year with something that is familiar for students and extend knowledge of estimation and rounding to include more work on rounding with decimals and significant figures.
Prior knowledge requirements
- Round numbers to nearest 10, 100, 1000
- Round decimals to 1 or 2 decimal places
- Estimate calculations using compatible numbers
