Reflection: Making Ten - Section 1: Warm Up

 

It was interesting to see the students with the two images of 6.  Students are starting to decompose some of the images to make it easier to add together.  One student looked at it as 6+6+2.  Another student saw it as a 6 and then counted on (counting the dots when they flashed), and one child saw it as 6+4+2+2.  

The important piece was allowing the students to share their thinking.  This allowed the others to see a variety of ways to find the sum of the dots.  I like to use the document camera because it allows for everyone to see as the student points to the dots and explains his/her thinking.
