iPad's Big Week
As of Thursday,
Apple reported selling 450,000 iPads in less than a week. Techies rushed to buy the tablets, checking out the latest apps and test-driving the various features. Even the youngest users had opinions to share: Watch this video of a toddler tester

Activity Ideas - Math
Together with your child, review the following figures:
Starting price for an iPad: $499
iPads sold during first week: 450,000
iPads sold on the first day: 300,000

Use the above figures to calculate the following: 
  • How many iPads would have to sell each hour to reach a total of 300,000 sales within a 24-hour period? 12,500 iPads per hour (300,000 iPads ÷ 24 hours/day = 12,500 iPads per hour
  • Based on sales per hour, calculate the number of iPads sold each minute: 208 1/3 iPads per minute (12,500 iPads ÷ 60 minutes/hour = 208.3 iPads per minute
  • Calculate the total first-day sales by the second: 3 1/2 iPads per second (208 per minute ÷ 60 seconds/minute = 3.5 iPads per second)
Bonus: Based on the iPad's $499 starting price, how much money did Apple make on April 3? $149.7 million (300,000 iPads sold x $499 unit cost = $149,700,000) How much is that per hour? $6,237,500 ($149,700,000 ÷ 24 = $6,237,500) Per minute? $103,958.33 ($6,237,500 ÷ 60 = $103,958.33

Words Rule!
It may be an old family classic, but Scrabble is anything but stodgy. The board game is breaking all the rules with a
new version, to be released in Britain over the next few months. Among the radical changes? Celebrity names and other proper nouns will be fair game. None of this will effect players in the U.S. 

Activity Ideas - Language Arts

  • Stage a spelling bee among family or friends.
  • Visit the Scripps National Spelling Bee website to choose from a list of commonly misspelled words.
  • Give each player at least five words that he or she will be responsible for. Have him or her find the words' definitions and pronunciations.
  • Have players take turns as judges—challenging one another to spell words— and as spellers. 
  • Compare the results. ASK: Does a word's definition help you spell it correctly? If so, how?
Bonus: Suggest players help each other come up with mnemonics—tricks or rhymes—to remember how words are spelled.

Everest ImageAn Everest Quest

At 13, Jordan Romero is well on his way to completing his life's goal—reaching the summits of the highest peaks on all seven continents. When he was 10, he became the youngest American to scale Mount Kilimanjaro, Africa's highest peak. Now he has set his sights on Mount Everest.

Activity Ideas - Language Arts
  • Encourage your child to learn more about Mount Everest: National Geographic Adventure - Return to Everest.
  • Have your child imagine that he or she is one of the first climbers to scale Everest. Suggest that he or she write a journal about this "historic" quest, to include details or anecdotes from the research.
