Students learn the value of multiplying a fraction with a value of 1. The concept is developed through the use of a variety of models that include pies, vertical bars, horizontal bars, areas, sets and number lines. Designed to work on an interactive white board. ***FEATURED TOOL Tool: Probability http://mathforum.org/mathtools/tool/97040/ Jim Reed Generate experimental probability results using a choice of a die, dice, spinner, suits, cards, or coin. Compare the experimental probability results to the theoretical probability. ***FEATURED TOOL Tool: Comparing Fractions and Percentages http://mathforum.org/mathtools/tool/95659/ BBC: Skillswise The aim of this module is to remind learners how to recognise equivalencies between common fractions and percentages, using factsheets, worksheets, an activity, a game, and a quiz at three levels of difficulty. For UK standards alignments, technical help, and further resources on the web, see the section "For Tutors." ***FEATURED TOOL Tool: The Random Ball-Picking Machine http://mathforum.org/mathtools/tool/96860/ BBC Predict the likelihood that a colored ball gets randomly selected out of a bowl. Then pull a lever to pick a ball at random, keeping track of which color comes out, and comparing the result with what you expected. ***FEATURED TOOL Tool: Shapeology http://mathforum.org/mathtools/tool/96948/ Wayne Allen Bateman A square is broken into a number of quadrilaterals. Reassemble the pieces into two-unit quadrilaterals, and then re-create the square from these. ***FEATURED TOOL Tool: Adding with Uncommon Denominators http://mathforum.org/mathtools/tool/95713/ Conceptua Math Teachers can use this tool to help students understand the terms "common denominators" and "uncommon denominators." Students learn how to determine a common denominator for two given fractions with uncommon denominator by multiplying one or both by a fraction with a value of 1. ***FEATURED SUPPORT MATERIAL Support Material: Inverses http://mathforum.org/mathtools/support/96418/ Wayne Allen Bateman This interactive multimedia tutorial introduces reciprocals or inverses, and leads into dividing fractions. ***FEATURED SUPPORT MATERIAL Support Material: Factors, Primes, and Factorization http://mathforum.org/mathtools/support/96431/ Wayne Allen Bateman This interactive multimedia tutorial explores prime numbers and factors, without the use of division per se.
