Most young mathematicians are aware that the planets don’t orbit the sun in a circle but rather as an ellipse, but have never studied this interesting feature. This resource looks at the planetary orbits in more detail and helps learners...

Students identify the functions of packaging food and how the designs work.  In this food packaging lesson students identify the changes that occur in different types of materials. 

Students explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Students identify different geometric shapes in the...

Ninth graders solve linear equations.  In this Algebra I lesson, 9th graders investigate the properties of equations (Reflexive, Symmetric, Transitive, Substitution, and Transformation Properties) and use these properties to solve...

Students identify pollution around their local community. They discuss the sources of polution and categorize objects based on their properties. They discover ways to make changes to the environment and how to inform the public.

Twelfth graders solve first order differential equations using the separation of variables technique. In this calculus lesson, 12th graders explain the connection between math and engineering. They brainstorm what engineers do in real life.

Sixth graders identify and describe the composition and physical properties of the layers of the Earth. They also explain how scientists used the scientific process to know about the center of the Earth. Finally, 6th graders read a...

Students simplify fractions. They convert fractions to decimals. Students comprehend the double number line and how to use it proportionately. They convert fractions to percentages using the double number line. Students use the...

Sixth graders estimate the measurement of angles and then measure the exact distance using an angle ruler. In groups, they explore shapes and recognize the characteristics acute, obtuse and right angles. Students sketch required shapes,...

Students explore math functions by completing a worksheet in class. In this spatial movement instructional activity, students utilize a four square grid and a penny to practice moving the coin horizontally, vertically and diagonally as...

Students explore fact families. In this math activity, students use links to model a fact family. Students solve addition and subtraction problems.

Seventh graders describe how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow. They consider the affects of pollution on groundwater supplies and write a letter drawing...

Sixth graders participate in a lesson plan that is about investigating the different layers of the earth and defining how the plates move over the mantle. They engage in a variety of activities and use mathematics to create projects to...

Students examine spiders. In these spider lessons, students will view spider images and live spiders to determine physical characteristics, habits, and habitats. Students will examine fantasy and folklore about spiders to create and...

Fifth graders recall prior knowledge about rocks. In this igneous rock lesson, learners work in cooperative groups to perform experiments to classify the properties of igneous rock. They write a detailed paragraph and illustrate the rock...

The design challenge: develop a method to separate steel from aluminum. The first lesson plan in an eight-part series introduces the class to the grand challenge of ciming up with a method to streamline a sorting process at a...

Show your class what goes on with a magnet that can be turned on and off with a resource that provides the information needed to build an electromagnet. The information allows the class to understand that creating loops with the current...

Imagine recycling food scraps and using them to make paper. The directions are all here in a seven-page packet that details several paper-making strategies.

Pupils examine a stress-strain diagram that compares the advantages and disadvantages of the two common bridge building materials, concrete and steel. The also consider the factors that influence the materials builders choose for their...

Students investigate points and angle bisectors. In this geometry instructional activity, students define angles, bisectors and perpendicular bisectors. They analyze angles and bisectors using Cabri software.

Students calculate the measurements of the inscribed angles of a triangle. In this geometry lesson plan, students relate the hypotenuse of a right triangle and the diameter of a circle to each other. They calculate the diameter of a...

Students differentiate between inscribed quadrilaterals and parallelograms. In this geometry instructional activity, students identify the shaped of the polygons when it is inscribed inside of a circle. They calculate the missing angles...

Students calculate the inscribed angle of a triangle. In this geometry lesson, students identify the angle created by intersection of a triangle and a circle. They see the relationship between the arc and the angle.

Students make conjectures of intersecting circles. In this geometry lesson, students observe circles and their position in space. They investigate and observe two and three dimensional objects.
