Tool: Math Is Fun - Rod Pierce http://mathforum.org/mathtools/tool/231934/ A website for students of all ages to explore different math concepts that interest them, or to get some extra practice. The site is organized under the topics: Numbers, Algebra, Geometry, Data, Measure, Puzzles, Games, Dictionary, and Worksheets. In addition there are links to a Teacher's Page, Feature of the Month, and more! Tool: Algebra Balance Scales - Negatives - National Library of Virtual Manipulatives (Utah State University) http://mathforum.org/mathtools/tool/19435/ Solve simple linear equations using a balance beam representation. Coefficients and constants may be positive or negative. Tool: Factorize - Shodor: Project Interactivate http://mathforum.org/mathtools/tool/224/ Learn about factors through building rectangular arrays on a grid. Tool: Making Change - Colleen King http://mathforum.org/mathtools/tool/31363/ Students are given the sale price and the amount of money paid by a customer. They must calculate the amount of change due, then click and drag the fewest number of coins and bills to make change. Tool: Slope Slider - Shodor: Project Interactivate http://mathforum.org/mathtools/tool/295/ This activity allows the user to use various controls to manipulate a linear function graphically. Tool: Place Value Chart - Ulrich Kortenkamp http://mathforum.org/mathtools/tool/181488/ This iPad/iPhone/iPod touch app provides an interactive place value chart. You can place tokens by touching the screen and move them around with your finger(s). Moving tokens between different places is only possible when moving from a higher to a lower place, or when enough supplementary tokens are available to be bundled. Removing tokens can be done by moving them to the top. The tool can be used either to demonstrate place value, or for self-exploring by students. One possible activity could be to find the fastest way to remove a certain number of tokens (say, 3 hundreds, 8 tens and 7 ones). Tool: Algebra Tiles - National Library of Virtual Manipulatives (Utah State University) http://mathforum.org/mathtools/tool/417/ Visualize multiplying and factoring algebraic expressions using tiles. Tool: Splash Math - Splash Math, Studypad INC http://mathforum.org/mathtools/tool/232136/ Splash Math offers lessons on number counting, addition, subtraction and others. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Quick Links...
