Teacher Supports. Below is the layout for a typical teacher page accompanying every episode in every video-based lesson in this project. Click on any feature below for a description.
Episode Supports
Episode Description
A short description of what the students do in the episode is provided. Additionally the episode type is named. There are 4 types of video episodes in these lessons:
- Making Sense –The goal of the lesson is presented, as is a math task related to the goal. These episodes focus on comprehension, meaning, and interpretation.
- Exploring – The pair of students investigates and solves a mathematical task. Their conceptual challenges and false starts are included.
- Reflecting – Students explain their reasoning and/or compare something (e.g., equations, graphs, or solutions).
- Repeating Your Reasoning – This is the “practice” component of a conceptual lesson. Learners are directed to stop the video, work on a task related to a previous problem, and then compare their work to that of the students in the video.
Students’ Conceptual Challenges
Points of confusion, misconceptions, or key difficulties are described, as well as how the students in the video resolved the challenges.
Focus Questions
Several questions are provided that address the key mathematical ideas in the episode. The time stamp is identified where you can stop the video and pose the question to your class.
Supporting Dialogue
Specific suggestions are provided for how you can support Math Talk among your students as they discuss the video for a selected episode. Different elements of productive dialogue are highlighted: revoicing, considering alternative approaches, using precise mathematical language, and engaging in productive disagreement.
Math Extensions
Several additional math tasks are included that you can assign to your students. These tasks extend, refine, or apply the ideas from the selected episode.

Lesson Description
The overarching goal and mathematical activity of the lesson is described.
Targeted Understandings
The mathematical ideas, connections, meanings and ways of reasoning that can be supported by the lesson are described. These include but go beyond the Common Core State Mathematics Standards.
Common Core Math Standards
The specific Common Core State Mathematics Standards addressed in the selected lesson are identified. Additionally, how each standard is met by the students in the video is elaborated.
Common Core Math Practices
One Standard for Mathematical Practice from the Common Core is highlighted for each selected lesson. Additionally, how the practice is exhibited by the students in the video is elaborated, along with relevant time stamps from the episodes.
The information provided in this section applies to the entire lesson, not just a selected episode. It can be useful for aligning lessons to district goals and for instructional planning.
A printable document is provided that contains all the text from the Mathematics in this Lesson section for a selected lesson.
A printable document is provided that contains the text and figures from all the Episode Supports for a selected episode.
Each lesson is split into 4-7 episodes. Most episodes last 3-10 minutes. This section provides information and suggestions for how to use the video from the selected episode in a math classroom.

Each lesson is split into 4-7 episodes. Most episodes last 3-10 minutes. You can select an episode by clicking on the number of that episode.
A printable document is provided that contains the mathematical task that is investigated in the episode. This allows you to stop the video at any time and ask your students to work on the task on their own.
Selecting this button brings up an online calculator. This choice is provided for episodes in which the students in the video use a calculator.
Some lessons rely on the prerequisite knowledge of students, such as recall of the Pythagorean Theorem or an ability to multiply binomials. In these instances, this button is provided. Selecting it links to more information about the prerequisite topic.
In some episodes, the students in the video explore applets that we created for them in GeoGebra. For those episodes, selecting this button takes you and your students directly to the applet.
