In addition to the digital time display, ClassTimer includes a bar graph style display so that young children can visualize the time remaining for a particular task. ***FEATURED TOOL Tool: Number Grid Level 5 http://mathforum.org/mathtools/tool/25844/ Quincy Brown Fifth 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 5 uses three and four digit numbers. ***FEATURED TOOL Tool: Volume http://mathforum.org/mathtools/tool/95285/ BBC: Skillswise This module is about finding out how to work out volumes, using factsheets, worksheets, and a quiz at three levels of difficulty. ***FEATURED TOOL Tool: Drawing Hyperbola http://mathforum.org/mathtools/tool/627/ International Education Software: Manipula Math Interactive page to draw hyperbolas. ***FEATURED TOOL Tool: Hands-On Math: Line Design http://mathforum.org/mathtools/tool/160014/ Ventura Educational Systems Hands-On Math LineDesign is an interactive learning environment where students can explore and discover the fundamental ideas of geometry. Encourage students to explore, discuss their findings and use math vocabulary while creating designs. Younger learners may use terms such as line, line segment, end point, intersection, rectangle, square, circle, and triangle. For older students, teachers may want to use some of the options available by tapping the grid icon. Based on the shape selected, either a rectangular or polar coordinate graphic system is displayed.

This inflation calculator is based on the inflation rate during the US Government Fiscal Year, which begins on October 1 and ends on September 30. This calculator computes inflation from 1959 to 2020.
