This narrative document describes the progression of Geometry across the K-6 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 geometry in three categories, namely, geometric shapes and their categories, composing and decomposing geometric shapes, and spatial relations and spatial structuring.

These 4 activities, part of the Mathematics Developmental Continuum of the State of Victoria, Australia, are intended to introduce learners to the problem solving skills of clarifying questions, making assumptions and choosing a solving strategy. Students are challenged to investigate problems in household math, open-ended planning projects, and Fermi questions. Supporting documents and progress indicators are included.

This Technology Problem of the Week (tPoW) shows a tangram set (one small square, one parallelogram, and triangles of three different sizes), assigns a cost to the smallest triangles, and then challenges students to determine the cost of the other five pieces and the overall value of the complete set. The tPoW further asks what fraction of the area of the large square each piece represents, and the percent of the total area of the large square made up of triangles. It links to the Java applet "Tangrams." Solve and explain your solution; download hints and answer checks. Free registration is required.

Villainy, Inc. is a website devoted to helping upper elementary grade students build and use problem-solving skills to solve unique and complex mathematical problems. Students become undercover agents working to thwart the evil Dr. Wick, ID and his often-zany schemes to take over the world. Student activities include finding areas of rectangles, calculating with decimals and percents, finding averages, estimating and comparing whole numbers and decimals, all presented in the context of an animated and interactive cartoon story. Students complete one or both of the missions online. Teachers editions for each mission are provided, as well as additional tips, answer keys, printable worksheets and connections to standards. Note that it is not possible to save work online.

This video, the first 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. This first video covers measurable attributes, weight and surface area of irregular objects, estimation, precision and accuracy, the independence of area and perimeter, and the choice of unit.
