I popped in to a 1st grade classroom today and saw a warm-up activity that I just HAD to share. Check this out.
Part of the daily routine is to show the number of the day (which is the number of days in school) using ten-frames. Each day a student gets to add another dot to the ten-frame. It was actually very cool that you can tell the kiddos draw the dots instead of just putting a sticker on. Mrs. Rodricks put adhesive magnet squares on the back of the ten-frames (which you see on the board), so the kiddos can move them around. When I walked in, the students were showing different ways to make 83 using two addends. See how Mrs. Rodricks recorded their expressions on the mini white board? The friends just slide the ten-frames into two columns to show the two addends. Brilliant, right? Then the class counts aloud each addend (practicing counting by tens) and confirms that the expression is 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!
Do you need a ten-frame template? Just click here to grab one that prints two to a page.
