Instructional Tips
Teachers can:
• pose situations to students and facilitate a conversation about what the shape of the graphical representation of each situation tells us about the situation;
• provide students with concrete materials and digital tools to build linear and non-linear growing and shrinking patterns, and support them in creating graphs to represent these patterns;
• support students in making connections between the shapes of the graphical representations and their rates of change (e.g., if the graph becomes steeper, what does that tell us about the rate at which the variables are changing?);
• encourage students to describe graphs and their rates of change using gestures, vocabulary, and other means that are accessible to them, along with mathematical terminology;
