Review Lessons 4.1 - 4.4

Unit 4 Day 5
CED Topic(s): 2.1, 2.2, 2.3


The goal of today’s task “Function Flurry” is to help students deepen their understanding of the relationship between linear and exponential functions: their rates of change, their y-intercepts, and their equations. 

Activity: Function Flurry



Lesson Handout

Answer Key


Have students work in groups of 2-4 on the Function Flurry task. If available, we suggest having students stand at and write on vertical non-permanent surfaces. This tends to foster greater group discussion, decrease the time it takes for a group to start a task, and lower the risk of trying out a new idea. It also gives you a good visual of where groups are at in the task and which groups may need some extra support or extensions. In order for this task to remain a thinking task, avoid giving answers or providing a set of steps that would allow students to arrive at a solution. Give them time to wrestle!


Near the end of class you may choose to have students present their solutions. Any remaining time can be spent getting caught up on homework or studying for tomorrow’s quiz!
