Today I introduced ten frames to the little Kindies that I was working with. We practiced counting the blue and red counters that we were using, being very careful to match one-to-one as we counted. Then we practiced recognizing numerals on flashcards, filling our ten fames, and saying how many more we needed to make ten. Once we had the hang of how ten frames work, we were ready for some centres.
One group worked with me. We turned a flashcard over, identified the numeral and counted out counters as we filled our ten frame with that many counters, all the same colour. Then we estimated how many more we would need to fill in the rest of the ten frame. After we agreed on an estimate, we filled it up using a second colour of counters. We talked about how ten is a very special number, and we need to know how many make ten. In the picture above, we learned that 8 and 2 make 10!
At the end of math centre time, we practiced some subitizing. I flashed a ten frame card to the students and challenged them to name how many dots were on the card without allowing enough time for them to count the dots. This recognition of knowing how many at a glance is called subitizing.
if you are interested in using ten frames with your class (recommended for use with Kindergarten to Grade 2), here is an excellent resource: It Makes Sense! Using Ten-Frames to Build Number Sense by Melissa Conklin. Click here if you would like to purchase this awesome book from Amazon.
