Define rays and half planes, including the concepts of boundary lines and prerequisite knowledge of coordinate planes. Given linear inequalities in one and two variables, your class will compare the differences. They will also graph...

Young mathematicians explore number values by utilizing food as a visual aide. They discuss the differences between halves, fourths, and eighths and how they are visually represented by a pizza. Then create their own pizza in class and...

We know theorems about circles—now what? Class members prove a theorem, with half the class taking the case where a point is inside the circle and half the class taking the case where a point is outside the circle. The lesson then...

Even kindergartners can draw triangles in circles, but the assessment task requires a bit more geometric knowledge. Scholars investigate triangles that have a diameter of a circle as one of its sides. They must consider triangles that...

Anyone can draw a square, but can you CONSTRUCT a square? Here is a resource that challenges math scholars to create steps to finish their own construction. They test their ability to read and follow directions to complete a construction...

In this multi-faceted introduction to pi, participants perform a bevy of pi-related activities. Ranging from measuring household items to singing pi songs and reading pi stories, this fun and non-intimidating resource serves to bring up...

Cool circle patterns! To investigate patterns of shading in circles, learners use the values for specific examples of the pattern to generate a verbal rule for the arrangement.

Gobble up a slice of the task. Scholars first consider the area of a whole pizza, half a pizza, and a quarter of a pizza. They then consider other central angles and develop a formula for the area of any sector of a circle.

Not all structures take the shape of a polygon. The 21st lesson in a series of 29 shows young mathematicians they can create polygons out of composite shapes. Once they deconstruct the structures, they find the area of the composite figure.

For any teacher who is planning a field trip to Missouri's Botanical Garden, this lesson packet is a must-have! In it, young learners engage in pre-visit activities so they will be prepared to get the most out of their trip. There are...

Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber bands...

Sixth graders inspect M&M's to complete statistical data. Students interpret percent of colors represented. They convert data from decimals, fractions, and percents. Using the data, 6th graders create a bar graph and a circle graph.

Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...

Young scholars study the concept of using a map as a tool with the usage of a balloon designed to mimic the features of the Earth with the major features marked and shown on the balloon.

Learners investigate the periodic table, the structure of the atom and the subatomic particles. In this periodic table lesson plan, students complete 5 activities in order to better understand atoms and the periodic table. They use...

Students calculate the strength of gravitational force exerted on the moon by the sun and earth. In this orbital lesson students view a demonstration to see the gravitational forces between bodies.

Pupils examine the layers of the earth and the basic composition and thickness of each. Using construction paper, each student models the layers of the earth.

Students investigate the concept of a compass and it has been used in the past and in modern times. They practice using it in the wilderness in order to test its importance in various exploring activities. Each activity is accompanied by...

Explore the concept of building equations for perimeter and circumference. Learners use rulers to measure the perimeter of half a sheet of paper.  Then fold the sheet of paper numerous times, each time measuring perimeter. ...

Learners investigate the production of proteins by the DNA. In this protein synthesis lesson plan, students use paper models to explore transcription and translation to make proteins using DNA. Learners answer 10 questions to demonstrate...

Students explore measurement in terms of pizza toppings. In this math lesson plan, students draw a circle using string and a ruler, determine areas of different size circles, find how many two topping pizzas can be made using 14...

Students identify different locations on a unit circle. In this precalculus lesson, students identify the different trig properties and rewrite the equation of a circle in standard form. They use mnemonic devices to help them...

Students measure the perimeter and area of their polygons. In this geometry lesson, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of triangles.

Students explore the human ear. In this biology lesson plan, students develop a better understanding of the various parts of the human ear as they explore a hands-on apparatus.
