This interactive Java applet allows users to explore estimating numbers of objects, length, and area, by displaying two sets of random shapes, lines, or irregular figures on the screen. Users are asked if the first set is more or less than the second set. Options include: two difficulty levels; displaying guess history; a hint button; and an optional scoring feature that allows users to keep track of the number correct.

This interactive applet gives students six problems to solve involving rectangular floor spaces and the connections between area and perimeter. Students allocate two-dimensional space based on the area and perimeter specifications of various party activities. (Note: all four corners of the rectangles are draggable).
Activity, Interactive Media
This 3-lesson unit focuses students on the interplay of the measurements perimeter and area. Lesson 1 gives examples of perimeter for a general polygon. Lesson 2 emphasizes the independence of each measure, and Lesson 3 has students layout a bedroom, calculating the measures overall and of the components. The unit includes six student resource sheets, including a summative assessment, and answer keys.

This narrative document describes the progression of Geometric Measurement across the K-5 grade band. It is informed both by research on children's cognitive development and by the logical structure of mathematics. The document discusses the most important goals for elementary geometric measurement. Among those are recognizing measurable attributes, comparing, connecting with number, estimating, and differentiating linear measurement from area and volume.

This interactive Java applet allows users to explore estimating numbers of objects, length, and area, by displaying random shapes, lines, or irregular figures on the screen. Options include: three difficulty levels for accuracy; displaying guess history; a hint button; and an optional scoring feature that allows users to keep track of the number correct.

This interactive Java applet helps students explore the relationship between area and multiplication. First, users are asked to input all factor pairs of a given number. Then, selecting each of those factor pairs, the user draws the respective rectangular array by clicking and dragging across a grid. Options include the use of the commutative property (e.g., user must enter both 2x4 and 4x2 for factors of 8 and represent them with different arrays), entering a number of the user's own choice, and an optional scoring feature allowing the user to keep track of the number correct.

This interactive Java applet helps students explore the relationship between area and multiplication. Users are asked to draw all possible factorizations of a number as rectangular arrays by clicking and dragging across a grid. Options include the use of the commutative property (e.g., user must enter both 2x4 and 4x2 for factors of 8 represented by different orientations of the array), entering a number of the user's own choice, and an optional scoring feature allowing users to keep track of the number correct.
