Below you’ll find a downloadable set of the cards as well as some videos of us playing around in a first-grade classroom. I’ll go ahead and admit that there is a speed element in the videos that makes me a little queasy but with that being said, the student was comfortable so I felt like we were working at the speed of learning.
Some food for thought before diving in and test driving…
- I have to keep reminding myself that students need lots of opportunities to count and produce sets which isn’t always the case.
- The act of composing AND decomposing groups of ten is a huge understanding which remains underexplored in many of our primary classrooms.
- The key is to not move students too quickly to base ten blocks because it can really undermine the development of unitizing.
- Even though we call these “Base Ten Cards”, first-grade students see them as “Snap Cube Cards”.
