Crew Hamill have worked really hard this week to round numbers to the nearest 10, 100 and then 1000. We began by identifying the multiple of 10, 100 or 1000 that was before and after our number. For example, if our number was 1235, the thousand before would be 1000 and the thousand after would be 2000. We then had to decide, using a number line to support, which multiple it was closest to and therefore which number we would round it to. We then learned a rounding rhyme to help us solve this more easily:
- Find the place (which place you are rounding to)
- Look next door (look at the column to the right)
- 5 or bigger? +1 more
- 4 or less? Let it rest
