In this activity students explore past iPhone sales by year and try to predict how many iPhone 7's, 8's, and X's will be sold during the 2017 sales year as well as in the future.
Wow! This snickers bar is huge!
Act 1 - Big question = How many times bigger than a regular Snickers bar is this?
Note: This is a remake of our 2014 "How Much Does a Lego Cost" activity
How much could the Lego Millennium Falcon cost?
Student first make a guess and then think about what information would be useful in order to determine the actual cost.
Then they use a random sample of Lego products to help figure the cost of this massive Star Wars kit. Students might take an average cost per block from the sample and proportionately extend that to the number of blocks in this kit.
Older students might make a scatter plot of the data and determine a line of best fit that models the cost of a kit for any number of bricks. Students might use their model to find the cost or number of blocks in other kits.

The official Atlantic hurricane season started on June 1 and doesn’t end until November 30th. Now Hurricane Irma is approaching Puerto Rico, the Dominican Republic, Haiti, Cuba, and Florida.
Encourage your students to join the conversation, knowledgeably, by using our activity. Students read about hurricane classfications and calculate the possible increases in destruction from various scaled events. Estimation, data analysis with graphs to study trends, damage expense, average frequency, and histogram are all part of this lesson.
Who's going back to school? - Students calculate the historical changes in U.S. population percentages of people who are going back to school and try to formulate reasons for these variations. 6.EE, 6.RP.3, 6.SP, 7.EE, 7.RP.3, 7.SP
Does it pay to get educated? - Students compare the earning power for people who have invested time, effort, and often money in order to strengthen their education and learning. 4.OA.2, 5.NBT.5, 6.RP.3, 6.NS.3, 6.SP.3 6.SP.4, 6.SP.5, 7.SP.4, MP.1, MP.3
How much does it cost to send you back to school? - Students work together to create a back-to-school needs list; confer and research to estimate the cost of these items; tally and compare the whole class's estimations. The final question concerns the amount of time needed to work to earn enough for these costs. 4.OA.3, 4.NBT.3, 6.SP.3, 6.SP.5, 7.EE.3, MP5, HSF, HSA
In this short activity, students learn the meaning and history of Labor Day as they look for patterns emerging from the Labor Day dates over the past years. Students then use those observed patterns to predict future dates of the holiday.
