If you fancy yourself an amateur mathemagician, here’s a new trick to add to your repertoire. A card is selected from a special pack – eavh card has a letter and a number. Spell out the number drawn, sort the cards into two piles, do a little arithmetic, and presto! The original number appears!<\/p>\n

<\/p>\n

You can read about how the trick works at this web page<\/a>, and also get yourself a pack of the special cards. Don’t forget to watch the video too<\/a>!<\/p>\n

This is just one of a whole bunch of “mathemagic tricks” on Dr Mike’s Math Games for Kids<\/a> – magic tricks that work because of math. To find more, visit the site, look for the search box, and search for “magic”. Also, stay tuned, I have another card trick one up my sleeve, that I’ll soon cause to magically appear on the site!<\/p>\n

On another topic, you know that Easter is coming up soon. Did you ever wonder how the date is worked out? Believe it or not, there’s a mathematical formula that gives the date of Easter in any year. A few years ago I condensed that formula into a worksheet that kids can use<\/a> to compute the date of Easter. Check it out, it’s a great exercise for practicing order of operations and division with remainders. There’s also a video demonstrating how to use the worksheet<\/a>.<\/p>\n

You should also drop by the Math\u00a0Games for Kids blog – there’s some light-hearted posts on what a Polar Bear is<\/a> or on what happens when English Proverbs are treated perfectly logically<\/a>, plus a more serious post on experiments in education<\/a>.<\/p>\n

Yours,
