Each will open in a new window, when its button is pressed. Converter Helps students to convert fractions to decimals and decimals to fractions. Sequencer Student learn about number patterns in sequences and recursions by specifying a starting number, multiplier and add-on. Clock Arithmetic Students learn about modular arithmetic operations through working with various types of clocks. Tiles Students learn about tessellation on quadrilateral figures by dynamically changing the shape of the quadrilateral through dragging corners.
Students deform a triangle, rectangle or hexagon to form a polygon that tiles the plane.
Corners of the polygons may be dragged, and corresponding edges of the polygons may be dragged. Type of polyhedron, length, width and height. Grid type, number of bending points on the line. Function and Algebra Concepts Simple Plot Students can plot ordered pairs of numbers, either as a scatter plot or with the dots connected. Statistics and Probability Concepts Histogram Students can view histograms for either builtin or user-specified data, and experiment with how the size of the class intervals influences the perceptions.
