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. http://media.mivu.org/mvu_pd/a4a/resources/shapesofalgebra/index.html |
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. http://media.mivu.org/mvu_pd/a4a/resources/applets/graph_table4_exp1.html 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. http://media.mivu.org/mvu_pd/a4a/resources/applets/practice1.html |
||
Practice Applet 2: In this applet students match function rules (equations) to their corresponding table of values. http://media.mivu.org/mvu_pd/a4a/resources/applets/practice2.html |
||
Practice Applet 3: In this applet students select the appropriate function rule for a given graph. http://media.mivu.org/mvu_pd/a4a/resources/applets/practice3.html |
||
Practice Applet 4: In this applet students sketch the shape of a function given it's equation. http://media.mivu.org/mvu_pd/a4a/resources/applets/practice4.html |

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. http://media.mivu.org/mvu_pd/a4a/resources/describinggraphs/index.html |
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. http://media.mivu.org/mvu_pd/a4a/resources/applets/2race.html |

Description: This activity provides an introduction to recursive notation. It includes instruction, as well as interactive practice http://media.mivu.org/mvu_pd/a4a/resources/recursion/index.html |
Recursion Practice 1: Practice identifying patterns and writing recursive notation using frames and arrows. http://media.mivu.org/mvu_pd/a4a/resources/applets/recursion_practice1.html |
Recursion Practice 2: Practice identifying patterns and writing recursive notation using next-now and recursive notation. http://media.mivu.org/mvu_pd/a4a/resources/applets/recursion_practice2.html |

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. http://media.mivu.org/mvu_pd/a4a/resources/mussels/index.html |

Comparing Linear and Exponential Models
Description: In this activity students compare linear and exponential models by listing their characteristics side-by-side in a table. http://media.mivu.org/mvu_pd/a4a/resources/comparelinexp/index.html |

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. http://media.mivu.org/mvu_pd/a4a/resources/categorizingpatterns/index.html |
Teacher Video: Categorizing Patterns: Introduction |
Description: In this activity students learn about and practice how to translate functions, and identify translations from equations of functions. http://media.mivu.org/mvu_pd/a4a/resources/translations/index.html |
General Translations Applet: In this applet students practice translating functions by creating graphs of translated functions, or writing functions from given graphs. http://media.mivu.org/mvu_pd/a4a/resources/applets/translations.html |
