geometry

Basic concepts of triangles are revealed through paper-folding activities.

Introduces different shapes and patterns and shows where they can be found in nature and in man-made objects.

A collection of puzzles challenging the reader to make shapes and designs out of toothpicks, coins, or buttons and then change the shapes in various ways.

Introduces a variety of shapes and invites the reader to count the number of circles, squares, diamonds, and other shapes in the accompanying illustrations.

"The mathematical concepts of perimeter, area, and volume are introduced as a child constructs ponds for fish and ducks. Readers learn the formulas for these measurements, while also learning about the history of pools and swimming. Includes a discover activity, history connection, and mathematical vocabulary introduction"--Provided by publisher.

Reinforces classroom learning of geometry skills such as points, lines, planes, triangles, circles, quadrilaterals, perimeter, area, and circumference.

"Re-inforce in-class geometry skills such as lines, angles, polygons, triangles and the Pythagorean theorem"--Provided by publisher.

"The mathematical concepts of perimeter, area, and surface area are explored as a student designs dream rooms for a school project; teaches the formulas to calculate area for quadrilaterals and triangles, and additional concepts include parallel lines, right angles, irregular polygons, decomposing shapes, and area nets, and features a discover activity, history connection, and mathematical vocabulary introduction"--Provided by publisher.

Uses simple problems and activities to teach kids ages eight to twelve about acute and obtuse angles, plane and space figures, and parallel and perpendicular lines.

A history of geometry built around five milestones in the field--the discoveries made by Euclid, Descartes, Gauss, Einstein, and Witten.
