First graders explore why the sun and moon seems to disappear and reappear creating day and night.

Second graders become aware that thermometer liquids expand or contract as temperature affects them.

Eighth graders explore three-dimensional objects (prisms, pyramids, cylinders and cones) to draw nets. They use the understanding of drawing nets to find the surface area of pyramids and cylinders.

Learners, while using a graphing calculator, graph systems of conic sections as well as identify their solutions. They complete various word problems dealing with conic sections with their calculators. In addition, students sketch graphs...

Seventh graders review different types of graphs such as bar graphs, line graphs, box & whisker plots. As a class, they read a story and construct graphs to solve the data in the story. Students play "Graph Jeopardy" which requires...

Students explore the concept of area. In this area instructional activity, students find the area of irregular shapes with right angles. Students break down each irregular shape into multiple regular shapes in order to find the area. ...

Students explore the concept of the coordinate plane. In this coordinate plane activity, students graph points on the coordinate plane using an applet. Students graph functions using an applet. Students play a Maze Game where they...

High schoolers explore the concept of fractals. In this fractals lesson, students play the "Chaos Game" via an applet. High schoolers place dots on the screen to recognize that they have created Sierpinski's Triangle.

Students explore the concept of functions. In this function lesson, students determine if the graph is a function by using the vertical line test. Students use an applet to explore the vertical line test on a variety of graphs.

Students make a bar graph. In this graphing lesson, students discuss why bar graphs are used and are shown bar graph examples. Students create their own bar graph to compare the heights of different things around the world. Students...

Students create a scale drawing. In this ultimate classroom instructional activity, groups of students create a scale drawing of the ultimate classroom. They explore the and explain the constructed design.

Fourth graders solve word problems using multiplication. For this multiplication lesson, 4th graders write and solve word problems using their prior knowledge of multiplication.

Students use the partial products algorithm to complete multiplication problems. In this partial products lesson plan, students are introduced to the algorithm and connect the relationship to multiplication and division problems.

High schoolers explore the concept of probability.  In this probability lesson, students use area to determine probability.  High schoolers use charts and spinners to help determine the probability of events such as flipping a...

Students create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

High schoolers define and identify shapes by name. In this geometry lesson plan, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.

Students explore number sense by completing a number set worksheet. In this fractions lesson, students utilize pattern blocks as a visual reference to the fractions they practice identifying. Students read the book Clean-Sweep Campers...

Students, after reading an explanation from a NASA Web-based textbook, demonstrate an understanding of the text by applying it to the calculations involving the motion of an airplane.

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 examine the mathematical concept of area. These activities and discussions may be used to develop students' understanding of this mathematical concept and will enable students to calculate the area of a random shape on a grid.

Tenth graders have been introduced to the concepts of translation, reflection, and rotation, and have practiced translating, reflecting, and rotating two-dimensional objects on the coordinate plane.

Students decorate the congruent faces and edges of boxes in exactly the same way. They teach the terms "congruent," "faces," and "edges" to their parents.
