The Rrst few times students engage in these activities, the teacher should demonstrate how the activity is expected to go. Once students are familiar with these structures, less set-up will be necessary.
Why: A Card Sort provides opportunities to attend to mathematical connections using representations that are already created, instead of expending time and eUort generating representations. It gives students opportunities to analyze representations, statements, and structures closely and make connections (MP2, MP7).
Construct It
Construct It indicates activities where students have an opportunity use digital tools that are equivalent to those of classical geometry to construct Rgures.
Draw It
Draw It indicates an activity where students have an opportunity to use digital geometry tools to produce a visual representation of a problem or scenario.
Extend it
Extend It indicates activities where students have an opportunity to use a spreadsheet to produce a sequence of numbers to see patterns and make prediction.
Graph it
Graph It indicates activities where students have an opportunity to use graphing technology to visualize a graph representing one or more functions with known parameters and use the tool to Rnd features like intersection points, intercepts, and maximums or minimums. Additionally, they may use sliders for exploring the eUect of changing parameters.
Group presentations
Some activities instruct students to work in small groups to solve a problem with mathematical modeling, invent a new problem, design something, or organize and display data, and then create a visual display of their work. Teachers need to help groups organize their work so that others can follow it, and then facilitate diUerent groups’ presentation of work to the class. Teachers can develop speciRc questioning skills to help more students make connections and walk away from these experiences with desired mathematical learning. For example, instead of asking if anyone has any questions for the group, it is often more productive to ask a member of the class to restate their understanding of the group’s Rndings in their own words.
