In this 4-lesson unit, students identify, compare, and analyze attributes of two- and three-dimensional shapes, and develop geometric vocabulary. Students use basic linear measurement, understand and create scale representations, and explore perimeter and area measurement as they design their clubhouses. Activity sheets (pdf), lesson extensions and other commentary are provided.

This 26-minute video, the second in a series of twelve, is part of the web-based course for K-8 teachers entitled Learning Math: Measurement offered by the Annenberg Foundation. Participants explore procedures for measuring and learn about standard units in the metric and customary systems, the relationships among units, and the approximate nature of measurement. In this video participants examine fundamental ideas such as unit iteration, partitioning and precision, ratio, and scale.

These 3 activities, part of the Mathematics Developmental Continuum of the State of Victoria, Australia, are intended to introduce young learners to estimating and measuring area using formal units (square centimeters). Students also use the formula length times width to calculate rectangular areas. Supporting documents, materials, and progress indicators are included.

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. Users are given a quantity and asked if the displayed set is more or less than that quantity. 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 Java applet helps users develop two-dimensional spatial reasoning skills. The applet allows users to choose from 12 pentominoes to place and combine on the drawing board. Each pentomino contains 5 square units connected to form different shapes. The user can flip, slide, and turn each pentomino. A set of five activities encourages students to build congruent shapes, create stair step figures, name them according to letters from the alphabet to which they are similar, and build shapes with varying perimeters. This versatile applet can also readily be used to address additional concepts including area, transformations, symmetry, similarity, tilings, and tessellations.

This 3-lesson unit provides young learners with multi-sensory activities that introduce the concepts of area and perimeter. Students position themselves to form a perimeter, and use craft sticks, geoboards and square tiles to form and measure areas and perimeters. Connections from children's literature are suggested, and learning and assessment materials are provided.

This interactive Java applet allows users to explore the relationship between area and perimeter of both rectangles and irregular shapes. In the "Auto Draw" mode a shape is given, and the user finds the area and the perimeter. In the "Create Shape" mode users create their own shape and give the area and perimeter of that shape. The activity allows users to explore the relationship between shapes with a fixed perimeter and variable area or shapes with a a fixed area and variable perimeter. An optional scoring feature allows users to keep track of the number correct.

This interactive Java applet allows users to explore perimeter and area and the relationship between them. The activity gives irregular shapes or rectangles on a grid, and then the user enters the perimeter and area of the figure. An optional scoring feature allows users to keep track of the number correct.
