This comic was in NSWTF’s Education Newspaper recently.

Male Teacher: I handed out some 2D shapes to my Kindy kids. The next thing… Two kids who got rectangles are crying.

Female Teacher: How come?

Male Teacher: They both wanted angles that hadn’t been damaged!

Came across this calculator, which would be handy for whole class demonstration. It has big buttons and a simple layout – just the essentials. Nice and big too.

Google has a calculator function, which can solve mathematical problems for you. But maybe you shouldn’t always trust the answers given?? Take a look…

It’s Only Tuesday

By , Tuesday, 20th November, 2007

Direct from The Onion – America’s Finest News Source, comes this article – It’s Only Tuesday – some days do feel like this don’t they 🙂

It’s Only Tuesday

WASHINGTON, DC—After running a thousand errands, working hours of overtime, and being stuck in seemingly endless gridlock traffic commuting to and from their jobs, millions of Americans were disheartened to learn that it was, in fact, only Tuesday.

“Tuesday?” San Diego resident Doris Wagner said. “How in the hell is it still Tuesday?”

Already the week is unbearable for these New Yorkers awaiting a subway train, and it’s only fucking Tuesday.

Tuesday’s arrival stunned a nation still recovering from the nightmarish slog that was Monday, leaving some to wonder if the week was ever going to end, and others to ask what was taking Saturday so goddamn long.

“Ugh,” said Wagner, echoing a national sense of frustration over it not even being Wednesday at the very least.

According to suddenly depressed sources, the feeling that this week may in fact last forever was further compounded by the thought of all the work left to be done tomorrow, the day after tomorrow, and, if Americans make it that far, possibly even Friday, for Christ’s sake.

Fears that the week could actually be going backwards were also expressed.

“Not only do Americans have most of Tuesday morning to contend with, but all of Tuesday afternoon and then Tuesday night,” National Labor Relations Board spokesman David Prynn said. “If our calculations are correct, there is a chance we are in effect closer to last weekend than the one coming up.”

Added Prynn: “Fuck.”

Believe it or not, it’s not even goddamn lunchtime yet for these commuters in Southern California.

Reports that this all has to be some kind of sick joke could not be confirmed as of press time.

Isolated attempts to make the day go faster, such as glancing at watches or clocks every other minute, compulsively checking e-mail, hiding in the office bathroom, fidgeting, or reading a boring magazine while sitting in the waiting room, have also proven unsuccessful, sources report.

The National Institutes of Standards and Technology, which oversees the official time of the United States, is flatly denying that it has slowed or otherwise tampered with Tuesday’s progression.

“The current Tuesday is keeping apace with past Tuesdays with no more than one ten-thousandth of a second’s variation at the most,” NIST spokeswoman Dr. Geraldine Schach said. “However, I sympathize with the common consensus that this week has already been a colossal pain in the neck.”

Labor Secretary Elaine Chao released a statement addressing widespread speculation that it might as well be Monday for all anyone cares.

“We understand this day has been tough on many of you, what with meetings mercilessly dragging on and an entire stack of files still left to organize,” Chao’s statement read in part. “Yet we urge Americans to show patience. The midweek hump is just around the corner, and we have strong reason to believe that Saturday will be here before you know it.”

“Go about your lives as best you can,” the statement continued. “Do not, we repeat, do not take a sick day, as it’ll make the rest of the week that much harder to endure.”

In the meantime, citizens are doing their best to cope with the interminable week, though Tuesday is still hours away from ending.

“The more I try to speed it along, the longer it almost seems to take,” said Dale Bouchard, a Chicago-based broker who has been waiting for today to be over since it first began earlier this morning. “Honestly, today could not have come at a worse time this week.”

In the meantime, the latest wristwatch consultations indicate that it is somehow still Tuesday, if that makes any sense at all.

Online Graph/Grid Paper Resource

By , Thursday, 1st November, 2007

graph-paperI needed some graph paper for an activity I was planning on doing with the class today. Of course, I couldn’t find a pad of the stuff already printed out, so I turned to my friend Google and came across Incompetech.com‘s site which allows me to generate exactly what I needed then download it as a PDF. They also had a heap of other different types of paper stationery.
