Manipulable graphs control the motion of these characters and their interaction with their simulated environment. By solving challenges with these characters and graphs, students encounter and build calculus concepts as well as other important mathematics, including the arithmetic of signed numbers, fractions, and ratios, and geometric ideas such as slope, similarity and especially area. MathWorlds is a fully scriptable application that allows teachers and curriculum developers to customize its interface and extend its fuctionality to meet the specific needs of their students. It also includes a number of activity template stationery documents that teachers and curriculum developers can use to create custom activity documents via simple drag and drop. Hours of mathematical fun with graphs, signed numbers and other big ideas.
Boats move around in a river with adjustable current.
All those mysterious word problems become visually clear. Graphs display and edit the position, velocity or acceleration of one or more actors. Meters monitor current values of functions. Controllers allow a student to use the mouse to change an actor's motion during a simulation run. Title, axis names, units, ticks, and label intervals can be changed in any display.
