Outlines the embedded mathematics in which important but hidden calculations are being done for communications in commerce. Explains two key concepts, error detecting codes and error correcting codes. Illustrates these ideas using two familiar examples, barcodes and ISBN numbers. (ASK)

Presents the steps and lessons for making the "Measure Me" doll in which students experience numeracy when they use their own birth statistics to create a doll. Through this sequence of activities, learners relate what they already know about themselves to new situations where they compare their heights and weights with those of other children.…

Presents a mathematical analysis of the game "twenty-four points" that aims to apply arithmetic operations on the four numbers to reach a specific number. This game can improve children's ability to do mental arithmetic. (ASK)

Many students have difficulty finding remainders instead of quotients in the division of two numbers. Students are too quick to use technology and cannot interpret the output correctly. Moreover, many students are not accustomed to doing different yet applicable mathematics. As with all branches of mathematics, modular arithmetic and congruences…

The purpose of this instructional packet is to inform teachers and parents about children's development of numeracy in the early years of schooling. "I Can Do Maths" questions are in a child-friendly format and require children to write, draw, count, and measure. Two "ezi-guides" are provided to make administration easier. Keeping track of the…

The World's Largest Math Event 6 (WLME 6) is the National Council of Teachers of Mathematics' (NCTM) celebration of mathematics and mathematics education and is the highlight of Mathematics Education Month. This year's event, slated for April 28, 2000, features the theme "Animals as Our Companions". This theme encourages students to…

Describes how one kindergarten classroom made pictographs and paper graphs of the students' acting preferences for a production of "The Wizard of Oz." Focuses on how the activity led to varied mathematics and literacy connections. Identifies implications from the Oz experience, including relating graphs to classroom contexts, using…

Presents an activity in which students try to find the least common multiple (LCM) for two numbers using calculators. (ASK)

Focuses on subitizing, the ability to recognize small numbers of objects. Discusses when and how it develops and whether it should be taught. Contains 31 references. (ASK)

Shares some explorations of Fibonacci sequences with a special focus on problem-solving and posing processes. (ASK)

Describes a game in which students strengthen their number sense by using mental mathematics to find and check factors and multiples of numbers up to 100. (ASK)

Presents activities to cultivate the tendency to see special qualities in numbers that can be played on certain calendar days. Includes games on the constant of the day, Fibonacci and golden ratio dates, primes, powers, December 25, and the day of the year. (ASK)

Presents ways to introduce number systems from finger counting to number words, to concrete materials, to the numerals invented by various societies to enhance students' number sense by learning about the systems of other cultures. (Contains 13 references.) (ASK)

Aims to help children understand difficult concepts according to their own particular learning styles and to keep students learning while maintaining their interest in and excitement about mathematics. Presents everyday mathematics games for students at every ability level to practice important mathematical skills. (ASK)

Explores the study of ordered pairs to allow students to demonstrate their own creativity, apply previously learned computer skills, evaluate their own work, and draw connections to other mathematical strands. Using a spreadsheet, students construct a drawing composed of connected ordered pairs, the inverse, and the negative of the drawing. (ASK)
