Reflection: Perseverance Counting On - Section 1: Number Work

 

You could do this lesson with any numbers as sums, I chose 11, 12, 13 because of the date and I wanted the students to lead the students to a pattern of +1, +2, +3 consecutive numbers.  

I had quite a few students that wanted to use more than 2 addends so I felt they needed a bit more guidance.

I then decided to ask the students what double can you think of to get to the sum of 11, 12, or 13. (my thought on this was doubles, doubles +1, doubles -1)

 6+6, 6+7 together and then I had the students go back to their seats.  They were off and running They saw that you could use numerous numbers to get to the sums of 11, 12, and 13.

  They got it!
  Perseverance: They got it!

Combine and Compare

Big Idea: Blending is not just for ELA teachers! Today students will learn to "blend" (combine) two sets of dots and then compare the number to another using greater than by playing versions of previous learned activities.
