Could you use a quick math activity to help your students practice identifying decimals in standard and word form? How about some comparing and ordering of decimals? I've got an activity that covers all of those for you:-)

When I created this one, we were just beginning our work with decimals (in grade 6), and my students had done a little bit of work with writing decimal numbers in word form. They had also worked on comparing decimals several times during the year, in our Daily Warm Ups book.


​Using the Decimal Matching Activity

The first step in the activity is to match each card with a decimal number in standard form to the card with the correct word form.

  • I allowed students to work alone or with one partner, and the matching didn’t really take that long.
  • I did have similar numbers (like 9.68, 9.068, 9.0068 etc), so the students had to read carefully and take some time to compare those similar numbers.

After Matching the Decimals

Once students had their matches, I checked them before they moved on to ordering the numbers.

Using the standard form cards only, students ordered the numbers from least to greatest. I did not check these at this time, but instead had them write the correct order on their recording sheets so I could check later.
​However, as I walked around and checked in with students, I found some that needed to have a conversation with me about why 2.006 is not larger than 2.06…  this was a good opportunity for individual conversations.


After recording the order, students had to choose 5 of the numbers to write in expanded form.

It was a relatively quick activity (10-15 min), and it gave me a good picture of these skills at this point.

The decimal matching activity is also part of a larger Decimal Unit Resources file that can be found on TpT.
