Numbers= & programs for smartboards Number, Problem Solving A mathematical based puzzle for IWB, iPad and Android that requires some careful numeracy thinking and some informed trial and error. When the resource opens you will see that both multiplication calculations give the same result of 3634. The highest number that can be the answer for both calculations using each of the nine digits once is 5568. The challenge is to arrange the numbers until both calculations equal 5568. The resource will take care of the calculating but the player will have to think hard about the results of multiplication to make progress. Tap one tile and then another to swap them. The resource requires a modern browser and will work on all platforms. Go to math puzzle. Investigations, Number, Problem Solving This resource was inspired by the Puzzle of the Month in the always informative newsletter by Andrew Jeffrey, also on twitter as @AJMagicMessage. For the solution you’ll need to see Andrew Jeffrey’s newsletter next month. Go to Puzzle Resource
The Thirty Greatest Mathematicians Click for a discussion of certain omissions. Please send me e-mail if you believe there's a major flaw in my rankings (or an error in any of the biographies). Obviously the relative ranks of, say Fibonacci and Ramanujan, will never satisfy everyone since the reasons for their "greatness" are different. Following are the top mathematicians in chronological (birth-year) order. Earliest mathematicians Little is known of the earliest mathematics, but the famous Ishango Bone from Early Stone-Age Africa has tally marks suggesting arithmetic. Early Vedic mathematicians The greatest mathematics before the Golden Age of Greece was in India's early Vedic (Hindu) civilization. Top Thales of Miletus (ca 624 - 546 BC) Greek domain Thales was the Chief of the "Seven Sages" of ancient Greece, and has been called the "Father of Science," the "Founder of Abstract Geometry," and the "First Philosopher." Apastambha (ca 630-560 BC) India Pythagoras of Samos (ca 578-505 BC) Greek domain Tiberius(?)

Math Teachers at Play 61 Researching 61 as a number tells us it's not just prime, but is a twin prime, a cuban prime, the 9th Mersenne prime exponent, and a Pillai prime. That's primo prime pedigree. It's a Keith number and thrice Fortunate. The Euler Zig Zag number for n is the number of alternating permutations (up-down-up-down arrangements) on n ordered objects.

GraphSketch Multiples and Factors In this activity, students identify multiples and factors and solve problems that involve finding highest common factors and lowest common multiples. Students will need a good recall of multiplication basic facts in order to be able to do these activities. Activity One and Game Discuss the definitions of multiples and factors (on the student book page) before your students begin this activity. This game could be extended by asking: • What are all the different products you could throw with the two game dice, one labelled 1–6 and the other 4–9? • There are two different ways of getting a product of 12: throwing a 3 and a 4 or a 2 and a 6. • What’s the probability of throwing a double? • Which squares in the game are easier/harder to cover? Harder to cover: a prime number [only 2 out of 36 combinations] and a multiple of 7 [only 6 chances out of 36].) Activity Two These problems ask students to find highest common factors and lowest common multiples. Answers to Activities
Challenge of the Week November 26 – December 3, 2010 A teacher announces that a test will be given on one of the five days of next week, but tells the class, "You will not know which day it is until you are informed at 8 am of your 1pm test that day". Which day will be the exam given? Submit your solution to challenge[at]math.washington.edu. The winner of this week's Challenge Problem receives a gift certificate for Baskin Robbins Ice Cream!

Teachers Love SMART Boards: Mathematics I was searching through my past blog posts and I'm quite surprised that I have not written a post about the amazing flash-based resources found on Crickweb. This site contains hundreds of quality interactive resources for children aged 4 to 11. For my U.S. readers, the activities are organized into three age groups: The Early Years (age 4 to 5), Key Stage 1 (age 6 to 7), and Key Stage 2 (age 8 to 11). Within each age group the activities are organized by subject area. The basic subject areas include Math, Science, History, and Literacy. Spanish, and even Design & Technology. The resources contained on this site are all interactive and very few of them require keyboard input. of the activities only require students to touch or drag objects. I've included a few screen shots but the best way to find what your looking for is to browse around and play with the activities. Sharing is Caring!
