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.

Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...

Students follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the...

Learners explore the relationship of angles as it relates to 2 and 3-D shapes. In this geometry lesson plan, students differentiate between acute, obtuse, right, alternate interior, exterior and adjacent angles. They manipulate a...

Students calculate the distance from the vertex of a triangle to the center. In this geometry lesson, students find the shortest distance between a point and the vertex of a triangle. They relate this concept of distance to the real world.

Students perform operation with secant and tangent lines. In this calculus instructional activity, students find the derivative and relate it to the slope of a line. They differentiate between secant and tangent as they intersect a...

Students define keywords that are important to solve problems. In this geometry instructional activity, students find the arc length and angle of a circle. They convert between radians and degrees.

Pupils build a Lego design and then work with a partner to reproduce that design. They guide the building of the reproduction by description only and then check their work.

Students work with a set of objects to set up both quantitative and qualitative classification systems. As a group, students follow an example to design and complete two classification systems using a set of objects provided. ...

Students identify how to classify living things. They classify various concepts including family members, kinds of clothing, numbers, shapes, and vocabulary words. They discuss how to classify various concepts and classify pictures of...

Students use triangles to find the length and slope of each side. After connecting the vertices, they add points based on their specific instructions. They use the Pythagorean Theorem to complete a worksheet to end the lesson.

Second graders count by 2's to get to 100. In this counting lesson plan, 2nd graders use the program Kid Pix to create stamps two at a time until they get to 100.

Students recognize similarities and generalize patterns. In this math and technology lesson plan, students develop an understanding of number patterning by grouping stamps and counting by 10s.

Students use tangrams, student literature, and Websites to explore shapes.

Students take an Internet field trip to research fractions. ESOL strategies include using pattern block manipulatives and pairing ESOL and non-ESOL students on computers.

Fourth graders examine and discuss the purposes and traditions of African ceremonial masks. They design and create African ceremonial masks using various materials.

Students practice drawing lines of symmetry after the teacher draws shapes on the board. They create a class symme"tree" using only symmetrical shapes to decorate it.

Fourth graders investigate the concept of computing the area using different shapes. They use prior knowledge in order to devise a formula for a parallelogram. Scaffolding is provided by the teacher to find the formula of area for...

Pupils in a teacher education program enhance their awareness of patterns. They discover how to support their students in developing this skill in mathematical terms. They role play the role of a K-2 student and collect images from...

Students demonstrate the elements of design by creating a digital photography portfolio of photos taken in and arond the scool. The edit photos using Photoshope to emphasize the element of desing in each phot.

Pupils investigate the ties that architecture and math have in common. They focus on works of architecture in the world that is considered of great significance. Students use the internet to find building images from around the world....

For this math worksheet, students fill in the missing boxes while investigating the concept of vectors. They determine if two vectors are orthogonal or parallel.

Students use the Pythagorean Theorem to explore sailboat design. In this Pythagorean Theorem lesson plan, two sides of a triangular sail are measured, and the theorem is used to calculate the third side. A worksheet, bulletin board...

Sixth graders create polygons. For this shapes lesson, 6th graders explore prefixes such as oct, tri, quad, pent, etc. and share their findings. Students use pattern blocks to create two different polygons and label them.
