Learners investigate surveying in this secondary mathematics lesson. They will explore a real world application of geometry and trigonometry as they create a plot plan using a geometry utility and calculate the area of the land parcel.

Students discuss the items needed to camp outside. They identify objects in a backpack and tell what the item could be used for. They hide the objects throughout the room and they are to find them.

First graders identify combinations and patterns in this lesson. They manipulate an alien picture with 10 arms - 5 red and 5 blue. They use an individual alien picture to identify as many combinations as possible. Students compare...

Identify triangles by their angle measures and side lengths by looking at and measuring angle measures and side lengths. Use Cabri Jr. to construct various triangles, then manipulate the construction to create the 6 types of triangles,...

Through the examination of the relationship between the lengths of the sides of a triangles students will learn the classification of triangles (acute, right, or obtuse).

Students model the soils layers using Oreo's. In this lesson students use their favorite food items to create a model of soil layers. A discovery lesson from a youth camp is adapted for classroom modeling and discussion of soil...

Learners construct frieze patterns using translations and rotations. They will discuss how frieze patterns are similar to jigsaw puzzles and use Cabri Jr. to build a triangle frieze pattern using rotations, translations, and reflections.

Young scholars explore the concept of angles formed by parallel lines.They graph two parallel lines cut by a transversal, then measure the angles formed by the transversal and record the data in a table. Learners make conjectures about...

Students investigate reaction rates.  For this seventh or eighth grade mathematics lesson, students collect, record, and analyze data regarding how the temperature of water affects the dissolving time of a sugar cube. Studetns...

Students study invention steps and design their own invention. In this invention lesson, students discuss inventions and the process of inventing. Studnets write in an inventor's journal and study various types of inventions....

Students study five of the seven life zones in North America. In this journalism lesson students use the Scientific Method working in teams. They use lab equipment and technology to create a presentation on five of the seven life zones...

Students read books, learn about the letter f, play with plastic toys, and more to do with frogs. In this frogs lesson plan, students also play a game of leap frog.

Young scholars graph lines using the calculator. In this algebra instructional activity, students graph lines of equations in the form y=mx+b. They input equations into the TI Calculator and graph using the slope and intercept. They...

Students discover how to estimate the age of redwood trees. They measure the trees' diameters by using string to calculate the circumferences. Students conclude by discussing the science of dendrochronolgy.

Students practice measuring the height of redwood trees. On a group walk, they observe the height of various trees and identify the species. In groups, they use their geometry skills and other techniques to measure the tree and determine...

Young scholars work together to discover how temperature changes can affect the density of water and air. They make predictions on what they believe is going to occur. They answer questions to complete the lesson plan.
