If you are planning to attend the T^3 conference in Chicago, make sure to come by Booth 16 to meet Suzanne, Max, and Craig. Also consider attending Max and Craig's talks on Saturday. \|/ As you browse the catalog, please take a moment to rate a resource, comment on it, review it -- join an existing conversation, or start a new discussion! ***FEATURED TOOL Tool: Money http://mathforum.org/mathtools/tool/19436/ National Library of Virtual Manipulatives (Utah State University) Learn about money by counting and making change. ***FEATURED TOOL Tool: Number Grid Level 1 http://mathforum.org/mathtools/tool/25840/ Quincy Brown First level in a collection of five Number Grid activities. It displays a section of a matrix containing a set of consecutive whole numbers. A move from one number to the next within a row is a change of one; a move from one number to the next within a column is a change of ten. Level 1 has two digit numbers. ***FEATURED TOOL Tool: A Plethora of Polyhedra http://mathforum.org/mathtools/tool/80441/ Humberto Jose Bortolossi This is a free JAVA applet that helps users to study spatial geometry in a dynamic and interactive way. Using it, the user can rotate, zoom out, zoom in and translate a plethora of polyhedra. Moreover, the program is able to compute topological and geometrical duals of each polyhedron. Geometrical operations include unfolding, plane sections, truncation and stellation. ***FEATURED TOOL Tool: Single Fraction Pointer http://mathforum.org/mathtools/tool/70750/ Shodor: Project Interactivate Graphically determine the value of a given fraction represented as a point on a number line. Graphically find a fraction whose value is the given fraction using an arrow on the number line as a guide. Single Fraction Pointer is one of the Interactivate assessment explorers. ***FEATURED TOOL Tool: Poly http://mathforum.org/mathtools/tool/17925/ Pedagoguery Software Inc. Poly is a shareware program for exploring and constructing polyhedra. With Poly, you can manipulate polyhedral solids on the computer in a variety of ways. Flattened versions (nets) of polyhedra may be printed and then cut out, folded, and taped, to produce three-dimensional models. ***FEATURED TOOL Tool: Resources for Interactive Whiteboards http://mathforum.org/mathtools/tool/81683/ Mathsframe.co.uk These simple maths resources for interactive whiteboards emphasize student differentiation and progression. All activities are linked to a key objective/objectives from the UK's Primary Framework. They are intended to be used for reinforcing and practicing key mathematical skills and concepts. ***FEATURED TOOL Tool: All About Ratios http://mathforum.org/mathtools/tool/15499/ Cynthia Lanius The "All About Ratios" activities are designed to introduce ratios in a concept-building way. The activities can be done on computers with Internet access or be printed. The author suggests that pairs of students work together at the computer talking to each other about the activities. Exercises and quizzes are checked on-line, and teachers can record the results. Practice answers are hidden under a tab so that students can easily check their answers. Problem solving answers are submitted and both the students' and the correct answer are returned. Teachers can circulate and record the students' responses.
