107 Favorite iPad Apps for K-8 Great iPad apps for K-8 Tablet computing and mobile devices promise to have a dramatic impact on education. A growing number of schools across the world are jumping on the digital bus and embracing iPads (less often, other tablet products) as the latest tool to teach literature in multimedia, history through games and simulations, and math with step-by-step animation of problems. Not surprisingly, student scores improve when they use iPads and their interest in school soars. In my school, we have been rotating one set of Pads this year through K-8.

Leonhard Euler (Swiss mathematician) -- Encyclopedia Britannica Leonhard Euler, (born April 15, 1707, Basel, Switz.—died Sept. 18, 1783, St. Petersburg, Russia), Swiss mathematician and physicist, one of the founders of pure mathematics. He not only made decisive and formative contributions to the subjects of geometry, calculus, mechanics, and number theory but also developed methods for solving problems in observational astronomy and demonstrated useful applications of mathematics in technology and public affairs. Euler’s mathematical ability earned him the esteem of Johann Bernoulli, one of the first mathematicians in Europe at that time, and of his sons Daniel and Nicolas. By means of his numerous books and memoirs that he submitted to the academy, Euler carried integral calculus to a higher degree of perfection, developed the theory of trigonometric and logarithmic functions, reduced analytical operations to a greater simplicity, and threw new light on nearly all parts of pure mathematics.

Leonhard Euler: Google Doodle Honors 306th Birthday of Swiss Mathematician Today’s Google Doodle celebrates the 306th birthday of Swiss mathematician Leonhard Euler (1707-1783), who made important contributions to the study of geometry, algebra, calculus, mechanics and number theory. Born Apr. 15, 17o7, in Basel, Switzerland, he was the son of a Calvinist minister who started college at the University of Basel at 13 and earned his master’s degree in philosophy by age 16. While Frederick the Great invited him to join the Berlin Academy at one point, he spent most of his career working in St. (PHOTOS: A History of Google Doodles) Getty Images Euler was one of the most published mathematicians of all time, penning more than 800 papers (many in Latin) before his death at age 76. Euler may also be the father of sudoku, for he created the Latin Square, “arrangements of groups of numbers in grids that do not repeat vertically or horizontally,” according to a 2005 Los Angeles Times article.

Standard Deviation and Variance Deviation just means how far from the normal Standard Deviation The Standard Deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma) The formula is easy: it is the square root of the Variance. Variance The Variance is defined as: The average of the squared differences from the Mean. To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers)Then for each number: subtract the Mean and square the result (the squared difference).Then work out the average of those squared differences. Example You and your friends have just measured the heights of your dogs (in millimeters): The heights (at the shoulders) are: 600mm, 470mm, 170mm, 430mm and 300mm. Find out the Mean, the Variance, and the Standard Deviation. Your first step is to find the Mean: Answer: Mean = 600 + 470 + 170 + 430 + 3005 = 19705 = 394 so the mean (average) height is 394 mm. Now we calculate each dog's difference from the Mean: So the Variance is 21,704 Formulas

Modeling integers When modeling integers, we can use colored chips to represent integers. One color can represent a positive number and another color can represent a negative number Here, a yellow chip will represent a positive integer and a red chip will represent a negative integer For example, the modeling for 4, -1, and -3 are shown below: It is extremely important to know how to model a zero. For example, all the followings represent zero pair(s) And so on... Adding and subtracting integers with modeling can be extremely helpful if you are having problems understanding integers In modeling integers, adding and subtracting are always physical actions. If a board is used with the chip, adding always mean " Add something to the board" and subtraction always mean "Remove something from the board" Here, we will use a big square to represent a board Let's start with addition of integers: Example #1: -2 + -1 Put two red chips on the board. Notice that big arrow represents the "+" sign or the action of adding

Binary numeral system The binary or base-two numeral system is a representation for numbers that uses a radix of two. It was first described by Gottfried Leibniz, and is used by most modern computers because of its ease of implementation using digital electronics--early 20th century computers were based the on/off and true/false principles of Boolean algebra. Binary can be considered the most basic practical numeral system (the Unary system is simpler, but impractical for most computation). Representation A binary number can be represented by any set of bits (binary digits), which in turn may be represented by any mechanism capable of being in two mutually exclusive states. 0101001101011 on off off on off on + - - + - + Y N N Y N Y In keeping with customary representation of numerals using decimal digits, binary numbers are commonly written using the symbols 0 and 1. 100101 binary (explicit statement of format) 100101b (a suffix indicating binary format) 1001012 (a subscript indicating base-2 notation)
