Explain to students that you can also round a number to the tenths place, by looking at the number after the tenths place, so the hundredths. This is the second digit after the decimal place. If the number is 4 or less, the number in the tenths place stays the same. If the number is 5 or greater, you add 1 tenth to the tenths place. You can use the decimal place value chart as support. Next you can show how to round to the tenths place by dragging the numbers to the decimal place value chart and looking at the hundredths.
Check that students understand rounding decimal numbers to the tenths place by asking the following questions:
- Which number do you look at to determine if you round up or down to the tenths place?
- What do you do if you have 5 hundredths?
- What do you do with the tenths if the number in the hundredths place is 5 or more?
