Fifth graders are introduced to the concept of surface area. They identify the surface and attributes of figures that are measurable. They describe and distinguish the measures of surface area and volume of the figures.
Seventh graders explore surface area. They study the difference between two and three-dimensional objects. The teacher leads a discussion about finding the surface area of different size cubes. In pairs, 7th graders use graph paper to practice finding the surface area of cubes. They write in their journal the methods used.
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 vertices.
Fifth graders explore geometry by participating in a group math activity. For this shape measurements lesson, 5th graders identify the differences in sides and vertices when comparing cubes, cones and other 3D shapes. Students collaborate with classmates to find the volumes, perimeter, weight and diameter of classroom objects.
Fourth graders view and identify three-dimensional figures. They analyze and discuss various figures, build three-dimensional figures, and complete various worksheets and worksheet discussion questions.
Fourth graders are introduced to the measures perimeter, area and volume. They read contexts using the terms and begin to develop meaning for each measure. Additional contexts are presented and the definition of each measure is clarified.
Determine the characteristics of three-dimensional models. Given instructions, the young mathematicians in your class use snap cubes to build a specified model. They then match two-dimensional pictures to a three-dimensional object. The final activity asks them to take pictures of the model and justify, in writing, the reason for their match.
Introduce the procedure needed to find the volume of a rectangular prism. Learners rank various prisms such as cereal boxes and tissue boxes from smallest to largest volume. They use an applet to find the volume and surface area of each rectangular prisms.
Fifth graders explore perimeter, volume and area and how they are used in everyday situations. In this geometry lesson students investigate the units of measure and begin to develop meaning for each. Then determine how to use them in everyday life situations.
High schoolers 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.
Students calculate the surface area of a sphere using the correct formula. In this geometry lesson, students differentiate between the surface area of different spheres and make comparisons. They use cylinders with base and non base.
Let's go fly a kite! Discuss the concept of two-dimensional and three-dimensional objects with your math class. They examine a triangle and discuss the face, vertices, edges, and angles. Then they build their own Tetrahedral Kites and fly them.
Students discuss the importance of examining crystals and experiment growing them. In groups, they complete a project in which they use groups in geometry just like crystallographers. They practice solving the groups and proofs and share their results with the class to end the lesson.
Students identify and sort a variety of two- and three-dimensional objects and compare and contrast their attributes. They identify shapes, locate shapes on the faces of solids, sort real objects and explain the sorting rule, and describe a pattern made with pattern blocks.
Seventh graders explore the concept of rectangular and triangular prisms. In this rectangular and triangular prism lesson, 7th graders identify various prisms as triangular or rectangular. Students discuss the various shapes of bases for prisms. Students find surface area and volume of prisms.
Students define properties of rectangular prisms. In this geometry lesson, students identify the relationship between two and three dimensional objects. They use Cabri technology to graph their figures.
A worksheet that could be used to teach, reteach the idea of combining shapes to create another object. There is a diagram of a house built with two blocks. They select the correct two blocks used and color them. The second picture is of a rocket made of three stacked blocks. Again they identify the shapes used by coloring them.
In this geometry worksheet, 2nd graders examine a table that contains pictures and names of 6 solid figures. They use the information to name 4 figures and to circle the picture that has the same shape. They choose between two black line pictures for each shape.
