Decimals are like the cool sidekicks for numbers less than 1. When ordering decimals, start with the whole numbers, then check out the tenths, hundredths, and thousandths. Here's a twist: unlike regular numbers, after the decimal point, values go down! So, 0.099 is less than 0.1 - 1 tenth is bigger than 0 tenths, 9 hundredths, and 9 thousandths.
Ready for the challenge? Play this quiz to practice ordering decimals. It might seem easy, but stay sharp! Read each question carefully and check out the answers before picking the right one. Let's avoid those sneaky mistakes!
