After your shopping spree last week at Toys R Us and Wal-Mart, the ATM (Automated Teller Machine) machine is the right place to be! Today you will continue spending your $1,000.00 on toys or other goodies and will use a spreadsheet to keep the total cost of all the toys just under $1000.00, tax included. And don’t forget that the total cost of all the items (tax included) must fall between $995.00 and $1000.00 or you lose all the money.
Here’s more good news! If you are able to spend EXACTLY $1000.00, tax included, you win an additional $500.00 "imaginary" cash to spend. Will YOU be the one? Good luck!
Spreadsheet Activity:
Can’t remember what you did last week? Here are a few reminders.
Now it’s time to use a spreadsheet for calculating the exact amount of money you’re spending and how much money is left to spend out of the $1000.00. You can keep your spreadsheet open on the screen and your browser loaded with the Toys R Us or the Wal-mart Web site. This will allow you to work more efficiently if you need to switch back and forth between the two programs to check new prices online or delete items from the spreadsheet that cost too much. Choose one of the following:
-
Start using an online, interactive working spreadsheet NOW! (This is everyone’s favorite.)
-
Create your own spreadsheet using the formulas in our online, interactive working spreadsheet as a guide. Simply click on the buttons labeled FN to view the formulas. You can do it!
-
Download and use the appropriate spreadsheet template.
Are you ready to continue your study of primary source documents? Remember, you were sent on different Time Travel Missions in weeks 14, 15, and 16, to learn more about primary source documents. Each mission helped you understand that ideas and information related to your research topic were somehow influenced by people and events in the past. You learned to draw conclusions about letters or photographs and come up with your own hypotheses about the time period during which they were created. Also, you learned that primary source materials help you "relate cultural similarities and differences to your personal heritage and environments." (Information Skills Curriculum, Competency Goal 3, Grade 5)
To illustrate this, let’s enter the TechKnow Time Warp to sneak a peek at Theodore Roosevelt’s mail. Where was he when he wrote the letter? How do you know? Try to guess the age of his son. Do you know that Theodore Roosevelt is quoted as saying, "I never would have been President if it had not been for my experiences in North Dakota?" Many of Roosevelt’s attitudes about and interest in nature and conservation were reflected in his establishment of the U.S. Forest Service, five national parks, and 51 wildlife refuges. Read the letter and discuss how it helps you understand why conservation was one of Roosevelt’s major concerns as President. Note the date of the letter (July, 1890) and the year he became President (1901). Now let’s visit TechKnow Time Warp and read his mail!
After linking to the Time Machine, roll your cursor over the green beam of light to reveal Secret Time Travel Mission #3, and then click on the green light to begin the adventure. (Shhh...Don't tell anyone, but your teacher wouldn't give him a high grade on handwriting or neatness.) Let's look at the letter!

Last week you spent some time questioning the information you found online. Always question the truth of what you’re reading online. Find out who wrote the information. Ask questions like:
Do I agree with this? Why or not? Do I want to learn more about this? Who else would like to know about this information? How can I share it? How do I know this is true?
