Common Core Math gaps at grade 2

The items below were gaps or holes that we found this past summer when viewing grade 2 common core vs. covered curriculum within Investigations. I am hoping that the new pieces that Pearson will come out with will address some of these issues. We do cover some of them a bit but we know that we have to include numbers to 1,000 much more. We currently cover the ideas to some extent, but we are not hitting the specific target of each skill. For example, our curriculum covers identifying numbers to 100 but not 1,000. We know that we have to help students work with larger numbers.

• Identifying numbers to 1,000 - read and write #'s to 1,000 using base 10 (number names and expanded notation)
• Adding or subtracting #'s to 1,000
• Adding up to 4 two-digit numbers
• Using symbols for unknown numbers (21=14 + x)
• Partitioning shapes
• Fluently add and subtract within 20 (*sums of all 2 one digit numbers)
• Telling time to the nearest five minutes

Our grade level has placed more emphasis on fluency with addition and subtraction this year. I am curious to see how this plays within each student's overall math abilities. Will we see any differences?

The biggest obstacle is pacing. We are suppose to get through our curriculum each year. However, each year it seems that there is more and more to cover or the target level in increased. Investigations is a spiral curriculum in which it returns to prior skills that were taught. instead of spending a few days on the topic/skills it is important for us to continue with the curriculum so we can cover all the material. We have spent time discussing this as a grade level team. We feel it is important to continue on. This idea has been difficult for a few teachers as some want to slow down and spend more time on certain skills. However in doing this, certain teachers do not cover all material that is essential to meet the common core or state standards.
At the moment, our goal is to continue on with our curriculum in hopes of completing all units. I see pros and cons to both situations.
