Fifth graders read and write decimals to the thousandths place — understanding that each place is ten times smaller than the one before — and write them in expanded form.
Students will be able to…
We know tenths and hundredths — but the places keep going! What is the place after hundredths, and how do we read a number like 3.427?
Project this and set each digit. Watch the decimal build — tenths, hundredths, thousandths — with each place ten times smaller than the last!
