Boolean Search - 2nd grade and Math games

Search Keys	Purpose	What did you find?
AND	2,170,000	I was surprised that ‘and’ found less than ‘not/or’. I don’t understand why that is true? However the first three sites were all free and two I had seen at Gastineau School as game sites that the RALLY staff let kids play.
OR	2,270,00	There are countless websites for math and educational programs for 2nd graders. Many are free and assessable. They are marketed for parents. According to their brief write up under the website address.
NOT	WINNER 6,260,000 – SO MANY SITES!!!	Interesting but standards came up on the first page of available links. Mostly state standards; for example Virginia.
“                    “	417,000	By far the least amount of sites!
*	3,340,000	More games – almost the same 12 or more that popped up for the ‘and’ search.
- (minus)	6,050,000	I put a minus in front of the 2nd grade part and the search engine still returned over 6million sites. I think more of the sites were math related and not grade level specific.
+ (plus)	2,030,000 hits	The same selection as the ‘and’ search
Others I used
Link  www.abcya.com/fourth_grade_computers.htm	4,480	A lot of teacher classroom websites came up…I think that the site is used in their classroom as a link for kids to play.
Title	1,350,000	Much the same.
Notes	www.abcya.com/fourth_grade_computers.htm	This site came up for all of the searches…not always in the first page but at some point it was an available link.
		There are a lot of ways to increase the odds of success on internet searches. This was a very helpful exercise because I have never been introduce to Boolean searchers before – despite all the times I have used the internet!
