Students explain how satellites help scientists to see more than with the unaided eye and how Landsat technology works. Students identify vegetation and fire sites in the rainforest and detect erosion along rivers. They are able to use...

Sixth graders identify and use area formulas for finding the area of geometric shapes.

Third graders pick up plastic ants scattered on the floor. They take them back to their desks, count them, and add their totals to those of other students.

Students discuss the nature of fractions and compare fractions based on a similar whole to determine relative size.

Students identify shapes and manipulate 2 and 3 dimensional objects. They view objects from different perspectives and review relative positions (near, far, between). They sing a shape song.

Learners view and discuss a video about the use of pattern block shapes to form pictures. They, in groups, form garden and quilt designs using pattern blocks and then decorate the room with their art.

Students investigate modular arithmetic and how to use it to solve real world problems. In this modular arithmetic instructional activity, students use computers to work on modular arithmetic after a teacher guided instructional...

Pupils practice identifying the comparative and superlative forms of language. The second phase of the lesson focuses on using the comparative and superlative forms actively in small group conversation.

Fifth graders explore fractions of whole numbers as they make fraction bead necklaces.

Students measure angles.  In this angle instructional activity, students draw angles.  They  use a protractor to measure angles and identify the angle as straight, right, acute, or obtuse. 

Students complete first day of school activities. Through instructor modeling and demonstration, they become acquainted with the rules and procedures for the classroom and school. Students create a book of their first day experience.

Students investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.

Students explore the concept of modular arithmetic and cryptography. For this modular arithmetic and cryptography lesson, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their...

Students distinguish between proper and improper fractions. They create a "Character Clue Box" that represents a fraction. Fractions are picked from a hat and then groups go outside and search for items that represent their fraction....

Learners interpret how to communicate information and ideas in ways that are appropriate to the purpose and audience through spoken, written, and graphic means of expression. They use information-gathering techniques, analyze and...

Students identify class and types of materials in our environment.  For this investigative lesson students work in groups to process information about what actions should be taken concerning solid waste.

Young scholars connect different mathematical concepts. They create a circle graph. Students then create a question in which they collect data in order to convert fractions to decimals and decimals to percents.

Students use physical models and graphs in order to solve problems that have their origin in the real world that require algebraic thinking. The words are changed into equations and inequalities in order to be solved. This requires...

Students discuss situations when it is useful to know exact weight of object as opposed to estimated weight, estimate weight of various items, weigh them on scale using ounces and pounds, and compare their weights on Guess Your Best...

Students calculate value of money in other countries, and explore how the economy affects the rate of exchange.

Students practice graphing a linear equation and a parabolic equation. They work cooperatively to select numbers, including fractions, which they will put into ordered pairs. Students explain their process to the class, discussing what...

Students discover certain equations produce straight lines. In this graphing lesson, students draw axis and problem solve to find coordinates to graph.

Learners will use inquiry science to complete an investigation. They create hypotheses predicting the changes water undergoes in becoming ice and determine how much ice needs to be melted to create one 8 oz. glass of water.

Learners gain the powerful tools of estimation, prediction, and averaging and discover the importance these tools have in daily living.
