Teaching Rounding
What it is
Rounding replaces a number with a nearby number that is easier to use: 47 rounds to 50, 23 rounds to 20. The digit to the right of the rounding place decides which way to go.
When a child is ready
Teach it once place value and number lines are understood.
If they struggle
Draw a number line between the two tens (or hundreds) and mark the number; the closer end is the answer. The rule '5 or more rounds up' comes after the number line makes sense.
