The first step in the activity was to match each card with a decimal number in standard form to the correct word form. Students were permitted 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 that the students had to read carefully and take some time to compare those similar numbers.

Using the standard form cards only (pic is blurry, sorry!), 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 did find 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 can be accessed for free above. It is also part of a larger Decimal Unit Resources file that can be found on TpT.
