Module 2 Building Number Sense - (Nov., Dec., and Jan.)

In this unit the students will be extending the counting, comparing, ordering two-digit numbers, and identifying number patterns in different contexts.  They will continue to compose and decompose numbers as well as working on strategies to extend their knowledge of addition and subtraction facts.  The students will work on place value for tens and ones.  The students are developing an understanding of equivalence and working to solve problems with the unknown in different positions.  
The students will be:
  • working with number patterns and counting.  This will include skip counting by 2's, 5's, and 10's.
  • recognizing the amount in a patterned set without counting them.
  • ordering and comparing numbers.
  • compose and decompose numbers to 10.
  • solving word problems.
  • applying strategies to add and subtract.
  • using addition and subtraction within 20.
  • relating counting to addition and subtraction.
