One of the perks of being a math instructional coach is that you get to visit classrooms on a daily basis. On one of those visits, I observed this 1st-grade number of the day routine using ten frames.
The daily routine begins by showing the number of the day (which is the number of days in school) using ten frames. Each day a student gets to draw another dot on the ten-frame. You could have students add a dot sticker, but it was kind of cool to see the kid-drawn dots.
What happens next is the magic of this routine. The teacher had put adhesive magnet squares on the back of the ten frames (which you see on the board), so the kiddos could move them around. When I walked in, the students were showing different ways to make 83 using two addends by sliding the ten frames into two columns. So what you see in the picture below is a student showing 83 as 50 + 33. Brilliant, right?
As students came up to show different ways to decompose the number, the teacher recorded their expressions on a mini whiteboard.
With each new way to decompose the number of the day, the class counted aloud each addend (practicing counting by tens) and confirmed that the expression was correct.
THEN, the class moved on to three addends! Just awesome.
Best question of the day: “So, class, no matter how we move the numbers around, what number will we always have?” EIGHTY-THREE!
