Link: Fraction Grids
http://my.hrw.com/math06_07/nsmedia/tools/Decimal_Fractions/Decimal_Fractions.swf Description of Learning Activity This tool helps students to visually see the connection between fractions and decimals. Students also work on adding different fractions and multiplying fractions with like denominators in a visual, manipulative way. Grids are available in major denominators from thirds to Hundredths. 1. Learning Activity Types
2. What mathematics is being learned? NCTM Standards
Proficiency Strands
3. How is the mathematics represented? The mathematics involved in this tool are adding, subtracting, multiplying and comparing fractions and decimals (visually). 4. What role does technology play? How does the technology fit or interact with the social context of learning? This tool allows students to manipulate different fractions when adding/subtracting or multiplying to see how it may change an answer or problem. Students are also able to practice solving such problems digitally without having to make copies of numerous kinds of grids. Students instead are able to change grid size, color of shading, and clear the gird as many times as they need. For those teaching Investigations: This site works fantastic with the adding/subtracting and multiplying lessons at the beginning of each fraction session as well to use while playing the "Fill Two" game in the Decimal Unit.

Name & Link to Tech Tool or Tool homepage: Fraction Tracks
Description of Learning Activity This tool allows students to play the Fraction Track game that comes in the Investigation Math curriculum on the computer. Students play this game to practice the skill of equivalent fractions and adding them together to equal a prompted fraction. To win students must add fractions together to move as many of their color coins from 0 to 1. Must have Java for this site to work. 1. Learning Activity Types

3. How is the mathematics represented? There are many math concepts represented in this tool. Students must be able to find equivalent fractions, add unlike fractions to equal a prompted fraction, and understand how to manipulate the sums to equal 1. 4. What role does technology play?How does the technology fit or interact with the social context of learning? This tech tool allows students to check their work as well as play the game on one board that is easily reset. It also presents each player with their prompt fraction without having to make copies of fraction cards. This game allows students to interact with each other to continue to learn and practice the skills of this unit. Affordances of Technology for Supporting Learning
