When they do, they learn. Using this resource, young mathematicians learn about platonic solids by actually building, touching, and examining the shapes. They connect their observations about the shapes to Euler's formula.

Fifth graders use interlocking cubes to build towers to represent factors of numbers and place the towers in the appropriate places on a Tower chart in order to look for patterns. They work in partner groups, and finish by writing...

In this models worksheet, students read about how models are used to communicate events or principles in science. They are given an example and answer 4 questions about models. They discuss accuracy and inaccuracy of models. They create...

Second graders read Cucumber Soup by Vickie Leigh. They make representations for the number of each kind of bug found in the book. This instructional activity is a terrific way to show students how fractions, decimals and percents are...

Students draw a net (a two-dimensional pattern that can be formed to make a solid) for making an open top box on grid paper. They cut out the net and fold up each side to form the open box and tape the sides, then find the volume of the...

Third graders investigate the commutative properties of multiplication and focus upon the setting of cubes in the correct patterns to solve problems. They differentiate between numbers that have multiple factors and prime numbers....

Students observe crystal growth of Epsom salts and the variables that hinder or help their nucleation and growth. They illustrate a series of drawings/pictures as the crystals grow. They look for the different shapes they form as well...

Learners are given organizing boards and play domino and cube games. These simple games provide fun and practice in categorizing, using dominos and unifix cubes.

Students identify lines of symmetry.  In this symmetry lesson, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Students cut shapes out of cookie dough and...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

Children play with barnyard animal cards to practice composing and decomposing numbers. With their "secret number" of animal cards in a cup, they shake and spill them onto a barn story board, counting how many animals fall in the barn...

First graders create a map and display an understanding of the cardinal directions. In this map skills lesson, 1st graders listen to stories where a map would come in handy, create their own map, and use the cardinal directions accurately.

A note-taking outline is given to learners which covers meat composition and quality, types of meat and storage, and cooking meat. By viewing pictures they learn to identify cuts of meat or poultry products. They discuss inspection and...

Here is a great learning task that focuses on the development of areas in computational fluency including strategies in mental math. Young learners are guided through a list of addition expressions that help them visually understand the...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

First graders represent, compare, and order numbers. In this counting skills lesson, 1st graders use manipulatives to demonstrate one-to-one correspondence and to represent numbers. This lesson includes a teacher script to guide the lesson.

Fourth graders define the term matter. They compare properties of solids, liquids, and gases. They describe how matter changes from one state to another. They classify objects as either solid, liquid, or gas.

Students complete an in-depth exploration of the European Union using the five themes of geography as a guide. In small groups, students use traditional and technological resources to answer questions about the European Union, with each...

Fourth graders use square tiles to help them explain the concept of square numbers.

Eighth graders experiment to decide if a box that is twice as big holds twice a much. They work the concept of volume and how changing dimensions affect it.

First graders investigate the changing states of water.

First graders investigate the various forms of water. They discuss the properties of water. They discover examples of water's various states and locate other solids, liquids, and gases in their homes.

Students discover the background and properties of minerals. They examine fluorite and record data after testing it. They use the internet to help them discover information about minerals.
