  • People need language to fully understand numbers. This discovery – long suspected, and now backed by strong evidence – may shed light on the way children acquire their number sense.
  • homesigners were given a set of objects and asked to use tokens to create a second set containing the same number of tokens as objects. Again, their accuracy dropped significantly above sets of three objects.

      Notice the number three seems to be the maximum. Does that correlate with subitizing without training?
  • Children learn this count list well before they actually understand that "four" refers to four objects rather than three or six, says Michael Frank at Stanford University in California.

  • there are ways to be even more efficient, more search-savvy. And it’s our responsibility to teach kids how to find and research information, how to judge its veracity, and when it’s time to ask for a grownup’s help.
  • CONFIRM CONTENT. It’s common to find the same phrases and sentences on different sites all over the Web because people duplicate content all the time. To determine the original source of the content, you can look at the date it was written, but that’s also not entirely accurate. When authors edit an article, that changes the posting date. So even if it was originally written in 2005, the date will say 2011 if it was edited last week. Again, here’s when you put on your journalist hat. Trustworthy websites typically have an “errata column” or something like it where mistakes or corrections are posted
  • KEEP IT SIMPLE. Use search terms the way you’d like to see them on a Web site.
  • ...10 more annotations...
  • DEFINE OPERATOR. This has to be one of the best items of Google’s offerings. To learn the definition of a word, just type “Define,” then the word.
  • ONE MORE SEARCH. It’s one thing to do a quick search for Lady Gaga’s birthday. But for more important questions that have a direct implication on your life, do one more search. Go deeper and find a second corroborating source, just like a journalist would.
  • FIND THE SOURCE. Russell knows first-hand that Web sites can sometimes publish false information. Though we all know how to find contact information for an organization, confirm the phone number, look for the author’s names and trustworthy hallmarks like logos,
  • FUNCTIONS GALORE. You can use Google to do calculations (just type in “Square root of 99″ or “Convert 12 inches to mm”). You can search patents, images, videos, language translations. And even if you can’t remember a Google function, you can easily search it.
  • LINK OPERATOR. The way Google ranks sites can be confusing. Sometimes even when a site has negative comments or reviews, it still rises to the top of the search list simply because it’s been mentioned the most. When you want to know what other sites are saying about the site you’re searching, type in “Link: www.yourwebsitename.com” and you’ll see all the posts that mention that site.
  • DON’T USE THE + SIGN. It might have negative side effects, Russell says. Adding the + sign will force the search engine to look for only that phrase and may tweak the search in a way you didn’t intend. That said, it’s a useful tool for looking up foreign words or very low-frequency words.
  • PAY ATTENTION TO “GOOGLE INSTANT.” In most cases, Google’s instant search function, which is fairly new, will accurately predict what you’re searching for and offer suggestions.
  • SWITCH ON SAFETY MODE. If you’ve got kids in the house, Russell suggests enabling safe search. In your Search Settings, scroll down to SafeSearch Filtering (or use Control F to find it quickly!) and choose what level filter you want to use. You can tailor it to every computer in the house. Google offers all kinds of safe search tips and functions on Google’s Family Safety Center.
  • CONTROL F. A deceptively simple tool, the Control F function (or Command F on Macs) allows you to immediately find the word you’re looking for on a page. After you’ve typed in your search, you can jump directly to the word or phrase in the search list.
  • LEFT-HAND SIDE TOOLS. Most people don’t notice these exist, but when you search a topic, a list of useful, interesting tools come up. For example, when you type in War of 1812, on the left hand side, you’ll see “Images,” “Videos,” etc., but below that you’ll see things like “Timeline,” which maps out a time sequence of events around the War of 1812 and links to each of those events. There’s also a dictionary, related searches, and a slew of other helpful links.
