How  does the shape of the surface of water in a container change as water leaks out? After tackling this question, learners take part in a similar activity with more complex figures.

What a great assessment to give young mathematicians in order to test their knowledge on two- and three-dimensional shapes. Learners name various shapes, identify the number of edges, faces, and vertices, match an unfolded version of a...

Kindergartners jump right into learning. Each lesson in this math unit is clearly outlined with materials, procedures, student outcomes, misconceptions, and solutions. All lessons and activities are aligned with Common Core math standards.

Kick-start children's education with this pre-school math unit. Offering 31 different hands-on learning activities that develop young mathematicians' pattern and shape recognition, basic number sense, and much more, this is a must-have...

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on to learn the...

'Tis the season for lights, tress, and ornaments! Use this comprehensive set of holiday-themed printables to work on shapes, color words, handwriting, matching, pattern recognition, graphing, and more! Learners will love the fun theme...

Float like a butterfly, think like a bee! Build a huge hive, hexagonally! Find out the reason that hexagons are the most efficient storage shape for the honeybees' honeycombs. This neat little video would be a sweet addition to your life...

Follow this engaging slide show on the calculation of polygon perimeter with some hands-on measurement of perimeters to solidify the concepts. On this webpage there are interactive assessment questions and links to related resources by...

This collaborative activity investigates the meaning of a trapezoid and a parallelogram. It begins by presenting two different definitions of a trapezoid. Learners are to reason abstractly the difference between the two definitions and...

Learners examine the painting "Old Man With A Gold Chain" by Rembrandt. They identify geometric shapes in the painting, measure these shapes and compare the relationships of these measurements.

Problem number 6 on the practice SAT involves solving for a distance on a line, which Sal does in about 2 minutes. His method of efficiently (and correctly) solving problems is an excellent model for students who tend to panic at the...

Sal deftly solves the straightforward algebraic equation in problem 9 in under fifty seconds. Additional problems involve points on a plane, algebraic word problems, geometric angles, and fractions, some of which he takes more time to...

An excellent lesson awaits your young scientists! In it, learners are invited to explore the world of pulleys, levers, and planes; simple machines that make lifting heavy things much, much easier. They watch video, and engage in hands-on...

A really useful resource contains 116 slides covering basic geometric concepts related to 2-D or plane shapes. Shape properties, translations, reflections, congruence, symmetry, and grid work are all laid out in a comprehensive and...

In this solids worksheet, students identify the characteristics of solids. They name solids and determine the number of faces. This three-page worksheet contains seventeen problems. Answers are listed on the last page.

Students work with rectangles to find generalizations for adding and subtracting odd and even numbers in part one of the lesson. In part two, students use geoboards to construct polygons, look for patterns, and find a general rule.

Define and identify the three basic forms of symmetry translation, rotation, and glides with your class. They cut out and arrange paper pattern blocks to illustrate symmetry, create a Cartesian graph, and design a rug with a symmetrical...
