  • To save water, only run the clothes washer with a full load
  • To run a load of clothes, it takes 40 gallons of water. If I ran 3 loads of clothes, how many gallons of water would I use?
  • Hint: What is repeated addition?
  • Answer: 120 gallons of water would be used.
  • If you turn off the water while you brush your teeth, you could save up to 4 gallons of water per day!
  • Sally was brushing her teeth and realized after 1 minute she needed to turn off the water to be a “water saver”. By doing this, Sally only wasted 9 gallons of water. Jason did not turn off the water at all while he brushed his teeth and washed his face. He wasted 24 gallons of water. How much more water did Jason waste than Sally?
  • Hint: What information can you eliminate?
  • Answer: Jason wasted 15 more gallons of water than Sally.
  • A television set can be operated for three hours with the energy saved from recycling a single aluminum can.
  • One can operates a t.v. for three hours. If Megan has 11 cans, how many hours can her television operate?
  • Hint: Megan has 11 cans. Each can provides 3 hours of television. Can you use repeated addition or multiplication?
  • Answer: Her television would be able to operate for 33 hours!That is 1 DAY and 9 HOURS! WOW!
  • Five trees are spared every year for each household that recycles its daily newspaper.
  • Eight houses in the neighborhood recycled their paper for a year. Five trees were spared per household that recycled. How many trees were saved from recycling newspaper?
  • Hint: Are the numbers written out that you need to use?
  • Answer: 35trees were saved!!
  • Turn in cans and bottles- You can make some money too; It really is so simple; Recycle, Reduce, Reuse
  • Bill loves to recycle, so he can get money for toys. This week Bill collected 9 cans to recycle. He gets 12 cents for each can he recycles. How much money did Bill make this week for recycling?
  • Hint: You need to write .10 to do your math problem. Once you get your answer, start from the right and count two places to the left to see where your decimal goes in your answer.
  • Answer: Bill received $1.08 this week for recycling.
  • The oil spill in the Gulf lasted for 91 days. The oil is still floating on the top of the ocean water today, harming our beaches and animals.
  • If 9 gallons of oil were spilling into the ocean every hour, how many gallons spilled into the ocean over 7 hours?
  • Hint: are there 7 groups of 9 OR 9 groups of 7?
  • Answer:63 gallons of oil
  • A century ago, the typical American walked three miles a day. Now, we drive our SUVs to the gym. Cars undoubtedly have contributed to the decline of exercise in America, and the advance of our obesity epidemic and POLLUTION.
  • Justin, Elise, Brittany, Mary, and Will used to walk 7 miles A DAYeach. Today, they only walk 30 miles A WEEK ALL TOGETHER! How many miles does each person walk in a week?
  • Hint: What are you using….multiplication, division, addition, subtraction? How many people are there?
  • Answer:How many miles does each person walk in a week? 6
  • ASSESSMENT
    The students will be assessed on participation in their groups as well as writing down the problems in the book we made.
    The students will then get a sheet of construction paper and come up with their own math problem about pollution and draw a picture(s) that go with the problem.
  • GPS
    M3N2. Students will further develop their skills of addition and subtraction and apply them in problem solving.
    -c. Solve problems requiring addition and subtraction.
    M3N3. Students will further develop their understanding of multiplication of whole numbers and develop the ability to apply it in problem solving.
    a. Describe the relationship between addition and multiplication, i.e. multiplication is defined as repeated addition.
    g. Solve problems requiring multiplication.
    M3N4. Students will understand the meaning of division and develop the ability to apply it in problem solving.
    a. Understand the relationship between division and multiplication and between division and subtraction.
    f. Solve problems requiring division.
  • GPS
    M3P1. Students will solve problems (using appropriate technology).
    a. Build new mathematical knowledge through problem solving.
    b. Solve problems that arise in mathematics and in other contexts.
    c. Apply and adapt a variety of appropriate strategies to solve problems.
    d. Monitor and reflect on the process of mathematical problem solving.
    M3P3. Students will communicate mathematically.
    a. Organize and consolidate their mathematical thinking through
    communication.
    b. Communicate their mathematical thinking coherently and clearly to peers,
    teachers, and others.
    c. Analyze and evaluate the mathematical thinking and strategies of others.
    d. Use the language of mathematics to express mathematical ideas precisely.
