100 Chart Playlist
You’ve found your way to our 100 Chart Playlist! If you are visiting this page, you either purchased our 100 Chart Field Guide or you are interested in just perusing the 6 videos in the 100 Chart Playlist. The videos will be helpful to you, BUT they are much more helpful if viewed alongside the comprehensive write-ups that are a part of our 100 Chart Field Guide.
We video and photograph constantly, and we use the artifacts that come from this documentation — captured simply by one of us grabbing an iPhone and pressing “record” — to understand our learners and critically reflect on our work. We offer these video and photo artifacts up to you not because we think we’ve got it all figured out, but because we truly believe the only way we can grow as teachers is to get to inspect our teaching, together. Bear with us through our non-professional video skills, disregard the silly things that our kids sometimes do or say over the course of a block, and know that there are plenty of things we’d do differently were we to erase the footage and re-capture it in an effort to offer you a vision of “perfect teaching.” Everything we offer is a bit raw but also so real. Just what we do every day as we work with our young mathematicians. We strive to make our teaching visible so that we can together ask the hard questions and build the best we can on behalf of the kids we are entrusted to teach.
In this video, you get a chance to look in on the first Math Block of the year for Navy Band, a cohort of 2nd-4th graders who are all new to the school. In this video, learners are introduced to the 100 Chart Thought Exercise and you can see how Kevin goes about initiating them into this Thought Exercise, while also using it as an opportunity to teach what it means to learn within this math community. Regardless of the Thought Exercise you decide to start with on the first day, it is most important to begin cultivating a culture of learning right away.
Video #2 gives you a chance to see what the 100 Chart Thought Exercise looks like in action. In this video, partnerships are spread across the room, with most of the kids choosing to sit on the floor with the 100 Chart between them. In this video, we zoom in on one of these partnerships, Boone and Juliet, as they work together. This episode takes place about 2 weeks after Video #1. Boone and Juliet have only worked together for a few days, and they are still finding their way toward a truly collaborative and mutually productive relationship.
In this video, we move to another segment of the 100 Chart Thought Exercise, the Public Share, which follows the oral reading of the prompts. During the Public Share, the whole group gathers in front of a large 100 Chart to follow the thinking of one partnership. The Public Share is a key element of the 100 Chart Thought Exercise; it gives the teacher a chance to attribute mathematical authority to the children and it provides many social and mathematical learning opportunities. This video takes place on the same day as Video #1.
In this video you see an example of a conversation in which Navy Band is observing as two of their bandmates, Ashrit and Elina (both grade 2), work together through one prompt of a 100 Chart Thought Exercise. You will see Ashrit and Elina adapt their communication as they receive feedback focused on speaking clearly, asking questions, and listening carefully. You also will see how the conversation was intended to serve as a model for all of the learners in Navy Band.
Video #5 is another example from Navy Band of a Public Share, just as we saw in Video #3, which was their first Public Share ever. In this video, however, we see that the learners in Navy Band have progressed from that first day and have grown in their ability to engage in challenging mathematical thinking while navigating the complexity of collaboration. The learners have come together as a highly collaborative, learning community.
The previous videos have given you a glimpse of early work with learners in this Thought Exercise. In this video, a learner in Indigo Band (5th-8th graders) is leading a Public Share. Although the members of Indigo Band are older than the learners in Navy Band, the setup of the 100 Chart Thought Exercise was similar. The prompts, however, will reveal the learners’ growing capacity to listen and reason with more challenging mathematical expressions.
Lily, who was in 7th grade at the time, stepped forward to share her reasoning for the Public Share portion of the 100 Chart Thought exercise. Lily had multiple years of experience at Long-View including many experiences with the 100 Chart Thought Exercise. Yet, she did not identify as a strong mathematical thinker. However, Lily’s sharing revealed just how capable she was of hearing, processing, and communicating mathematical ideas. Also, as she shared her thinking, it became clear the extent to which she has developed automaticity with arithmetic thinking across various number forms.
