Math in a Minute

Volume 3 Issue 7


The amount of trash that we produce is outrageous!  Learner can explore different "going green" facts to draw their own conclusions about the need to recycle. These facts can help learners formulate great questions that need math to answer!  Check out these facts and some of the questions that might arise!

  • Recycling one aluminum can saves enough energy to run a TV for three hours -- or the equivalent of a half a gallon of gasoline. If I recycle an entire 12-pack of cans, how much energy am I saving?
  • Recycling one aluminum can saves enough energy to listen to a full album on your iPod. Recycling 100 cans could light your bedroom for two whole weeks. If I recycle an entire 12-pack of cans, how much energy am I saving?
  • We use over 80,000,000,000 aluminum soda cans every year. About how many soda cans do we use each day?  About how many soda cans do we use each month?  About how many soda cans do we use each week?
  • To produce each week's Sunday newspapers, 500,000 trees must be cut down. About how many trees do we cut down to produce an entire year's worth of Sunday newspapers?
  • If you had a 15-year-old tree and made it into paper grocery bags, you'd get about 700 of them. A busy supermarket could use all of them in under an hour! About how many grocery bags does a supermarket use in a day?  How many trees does it take to supply a supermarket with grocery bags for an entire day?
  • Americans use 2,500,000 plastic bottles every hour! About how many plastic bottles do Americans use in a minute?  
  • Rainforests are being cut down at the rate of 100 acres per minute!  About how many acres of trees have been cut down since we came to school?
  • The average person generates over 4 pounds of trash every day. About how many pounds of trash have you generated since school began in August?  About how many pods of trash do you generate since Monday?
  • Over 75% of waste is recyclable, but we only recycle about 30% of it. About how much of our waste do we not recycle?

Stop Collaborate and Listen

Stop Collaborate and Listen was a huge success!  We had over 70 educators, student teachers, and principals attend the after school workshop!  During these times we were able to discuss the upcoming 9 weeks and gain a better understanding of what is expected for our learners.  

Our next Stop Collaborate and Listen will be in January.  We will cover the 3rd nine weeks content!  We look forward to seeing you there!

Educator Academy

Educator Academy this month covered Fluency and included Number Talks.  All the resources presented along with some additional ones have been uploaded to the website (on the left-hand side under Resources).  We have also included a page that has Number Talk prompts for different grade levels that cover different mathematical topics.  Please let Ashley or Diana know if you would like any additional information.
