The Shapes of Algebra

Description: In the shapes of Algebra, groups of students graph 4 different functions and identify which function is not like the others. In the process they explore features of tables and graphs of various function families. The activity concludes with a practice section in which students use a variety of representations to identify function families. The online version of the activity includes several automated practice applets to support graphing and identifying function families.

Graphing Applets: These applets each contain tables for graphing 4 different functions and a graphing tool that creates a graph of each function for comparison.

Other Groups: Group 1 | Group 2 | Group 3 | Group 4 | Group 5

Practice Applet 1: In this applet students identify which function is not like the others by looking at their equations.

Practice Applet 2: In this applet students match function rules (equations) to their corresponding table of values.

Practice Applet 3: In this applet students select the appropriate function rule for a given graph.

Practice Applet 4: In this applet students sketch the shape of a function given it's equation.

Describing Graphs

Description: In this activity students write the story of a race between four sisters, given a graph of the race. Students also have the opportunity for interactive practice with drawing and interpreting graphs. Finally, there is a practice section in which students identify appropriate graphs for given scenarios.

Two Brothers Race Applet: In this applet students interact with a graph of 2 brothers racing cars. Students can draw graphs based on stories, develop stories based on graphs, and experiment with graphs in a "free play" mode.

Lilly's Mussels

Description: Apply a linear and exponential model to a small data set in order to explore the differences in growth pattern, depending on which model is selected.

Categorizing Patterns

Description: In this activity students explore the characteristics of various function families by comparing the patterns in six different tables of values and identify which type of relationship is shown in each one.

General Translations

Description: In this activity students learn about and practice how to translate functions, and identify translations from equations of functions.

Hey, I'm a little late in trying this applet out. Did anyone try printing at the end? does it give you your results for the entire tutorial? It would be nice to have students complete this at home for homework and bring in their results.

When you click on the story or draw tabs it says "Ryan's red car" in the instructions.

the two brothers race doesn't identify WHICH red/blue is RYAN.

Great job Dave. Thanks. This is so much easier and user friendly.
