Students walk around the neighborhood and identify various polygons and lines in buildings, nature and other objects. They design a building using various geometric patterns, shapes and lines. Students complete a descriptive writing of...

Using a word problem, learners practice estimation techniques. After leading the class through a solution to this problem, a teacher could have the class complete other estimation activities using this one as a model.

Geometers calculate the area of plane surfaces using the formulas for the area of a square, rectangle, and triangle. They develop the formula for calculating the total surface area of two geometric solids: the cube and rectangular prism.

Students study about perimeter and the units used to measure perimeter using a variety of materials including their hands, feet, rulers, and computer applets. They understand such attributes as length, area, weight, volume, and size of...

A hands-on activity uses the Zome modeling system, and helps young geometers either learn or review their knowledge of polygons. Students build as many different 2-dimensional polygons as possible: triangle, square, rectangle, pentagon,...

Students explore mass measurement. They complete a diagram of a triple beam balance. Students explore using the triple beam balance to determine the mass of an object. They discuss procedures for using the triple beam balance.

Students will develop an understanding design space. The arrangement of shapes is taught to create simple perspective. The differences in the size of shapes is shown in order to help learners see how they should be arranged in...

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

Students explore measurement. They use appropriate units of measurement for different sized objects. Students collect their data and enter it into an Excel data base. They graph their findings and analyze their outcomes.

What kinds of birds live in your area? Read a book about birds to your learners and explore their feeding patterns. Charts and graphs are provided in this three page packet, but consider assigning the basic questions if using with young...
