Students travel “around the world” with a partner or individually completing problems related to Lessons 4.5 through 4.8.
Prep: To prepare for today’s Around the World review activity, print the questions and cut them up into individual cards. We suggest printing on cardstock or laminating the cards. Distribute them around the room (they don’t have to be alphabetical) or hang them up on the wall. This is also a fun activity to do in the hallway if you want to change things up a little! Give each student a recording sheet (found under "Additional Materials").
Play: Have students travel “around the world” with a partner to complete the problems, keeping track of their work in the appropriate box. They do not need to go in any particular order as long as they write their work for problem A in box A and so on, so that their work is easier to check later on.This is a great opportunity to use conversation and observable as an informal assessment of where students are at in their learning.
Even if students haven’t done all the problems, use the last 5 minutes of class to have students reflect using the questions in the last box of the recording sheet. This will help students determine what they still need to study for tomorrow’s quiz. Note that many of the questions are focused on writing exponential functions that model a scenario, and we’ve purposefully varied the ways in which the information is presented. Make sure students feel comfortable writing an exponential equation from a graph and from a scenario, whether the context includes half-life, a rate of growth/decay given as a percent, or a verbal description of how a quantity is changing.
