Make a new version

Ordering decimals: a worked example (Order 2.4, 2.37, 2.3 and 2.305)

Give every number the same number of places: 2.400, 2.370, 2.300, 2.305.
Compare them like whole numbers: 2,300 < 2,305 < 2,370 < 2,400.
So the order is 2.3, 2.305, 2.37, 2.4.

How to use it at home and in class

At home

Have your child write the zeros in pencil above each number before ordering. Once they can see 2.400 and 2.305 side by side, the order is obvious. For the race-time problem, remind them the smallest time wins. Ten problems a day works better than a whole sheet at once. Mark them together with the answer key, then ask your child to explain one they got wrong: finding the mistake themselves is where the learning happens.

In class

Use the first row as a warm-up, a full page for independent practice, or five questions as an exit ticket. For a retake or a second group, make a new version with the test maker so every child gets different numbers.

Mistakes to watch for

Thinking a longer decimal is bigger, so 2.305 comes after 2.4.
Writing the order backwards when the question asks for greatest to least.

What to practice before and after ordering decimals

Before: decimals on a number line. If this sheet is a struggle, go back a step.
After: subtracting decimals, once this one is mostly right.
Learn it first: the ordering decimals lesson and the decimals chart.
