This year, my school has decided to put a huge emphasis on what it means to have “number sense” in the primary grades. In order for this to happen, we had to put an emphasis on a few key questions:
- What does it mean to be fluent?
- How do we assess number sense?
- What are the “wish list” strategies that we want kids to come in with at each grade level?
No, we don’t have the answers to all of these yet, but we do have a strong(er) grasp on what we DON’T want to do with our kids.
In first grade – we did NOT want to teach them algorithms that were only going to hinder their understanding as they progressed through the grades. So, as one of my teammates said, “We don’t stack, we go flat!”
