This iOS app is an open-ended tool for exploring a variety of mathematical topics. Learners stretch colored bands around pegs to form line segments and polygons in order to make discoveries about perimeter, area, angles, congruence, and fractions. Users can switch from a 25-peg board to an expanded 150-peg board and fill in the interior of shapes with transparent color.

This web unit offers suggestions for using geoboards to explore the length and area of two-dimensional geometric figures. The introduction describes materials needed, offers discussion and activities for investigating length and area (in particular, Pick's Theorem), and provides sample pages of dot paper to print out. Five lesson plans focus on lines, squares, rectangles, parallelograms, and right triangles, and a short bibliography rounds out the unit.

In this 28-minute professional development video, teachers focus on geometry and spatial relations by having students explore shapes that tessellate and have the same area. Teachers from different grade levels collaborate on what they want their students to be able to understand and accomplish. Viewers can watch how a 3rd-grade teacher guides his students in understanding area through the application of tessellations. Support Materials includes a Sidewalk Capers Lesson Plan.

The applets in this Interactive Geometry Dictionary (IGD) will allow students an opportunity to explore finding the area of some common shapes. The applets demonstrate how to find the area of a triangle using the area of a parallelogram, which in turn can be found using the area of a rectangle. This tool also supports the lesson "What's My Area" cataloged separately.

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 document provides descriptions and examples of what each Mathematics Common Core standard means a Grade Three student will know, understand and be able to do. This "unpacking" of the standards provides instructional guidelines and was developed to assist North Carolina educators teach the Mathematics Common Core (Standard Course of Study).

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 lesson plan makes real world connections as students explore the ability to estimate the surface area of an oil spill. The lesson provides surface area information about the 2010 oil spill in the Gulf of Mexico, and gives students opportunities to estimate small oil spills of their own making. This lesson includes two students activity sheets, one fractional amount overhead sheet, assessment and extension suggestions, and questions for reflection.
