Curated OER
Side Splitter Triangles
Students investigate the side splitter theorem. In this geometry instructional activity, students estimate and solve problems dealing with ratios and proportions. They identify angles created by lines that are parallel.
Curated OER
Areas of Polygons
Students calculate the are of regular polygons. In this geometry lesson, students create polygons on the computer and move it around to create different shapes. They explore the area of different polygons and how they inter-relate.
Curated OER
Quadrilateral within Quadrilaterals
Students investigate the properties of quadrilaterals. In this geometry lesson, students solve problems dealing with construction and designs. They work with quadrilaterals, midpoints and parallelograms.
Curated OER
Investigating Pythagorean Triples
Students investigate and solve Pythagorean triples. For this geometry lesson, students find the missing sides and angles of a right triangle. They graph right triangles and move the sides around to create different angles.
Curated OER
Tessellations Lesson
Fifth graders demonstrate their understanding of tessellations by watching a teacher prepared Powerpoint presentation and completing an activity. The students work independently to identify tessellations.
Curated OER
Finite Geometry
Young scholars solve for the area and perimeter of polygons. In this geometry lesson, students identify repeated patterns and create formula to solve problems. They make conjectures and prove hypotheses.
Curated OER
Orthographic Drawings
Students investigate the creation of three dimensional drawings. In this geometry lesson, students analyze and complete orthographic drawings. They Cabri software to manipulate and move the drawings around.
Curated OER
Discovering Euler's Theorem
Students identify different parts of a prism and polyhedra. In this geometry lesson, students identify the number of faces, edges and sides of polygons. They solve problems by recognizing patterns.
Curated OER
Menelaus' Theorem
Students investigate Menelaus Theorem. In this geometry instructional activity, students calculate the area of polygons. They differentiate between boundaries point, interior points and area of lattice points.
Curated OER
Water Pressure - Observing Water Flow
Students discover that pressure increases the deeper the ocean becomes. They determine how water pressure differs at various depths by observing water flow.
Curated OER
Scientific Notation III: Linear vs Exponential
Learners examine the differences in exponential growth and linear growth of a system. They interpret data on graphs and develop their own charts. They answer discussion questions as well.
Curated OER
How is Your Driver Doing?
Sixth graders explore the concept of averaging of numbers and the function of a spreadsheet. Data is collected, analyzed, and displayed in this lesson. The NASCAR race results provides the basis for the collection of data.
Curated OER
