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
- 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
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.
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 Operations Activities Bundle file that can be found on TpT. For more about decimals, check out the Rounding Decimals post, with a FREE math wheel download.
