Eighth graders explore similar and congruent figures and objects. They are given objects, figures, and geometric terms, 8th graders classify items by property. Pupils explore sets of congruent and similiar figures and use observations and measurement to make conjectures. Students make conjectures about ratio, and proportion.
Students investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and explore the properties of these objects.
Students problem solve to open a cube to create different shapes. In this problem solving lesson plan, students are given a cube and the shapes to open it up to, and they have to cut the cube open to make certain shapes. This gives them a better understanding of 3 dimensional shapes.
Students identify the formulas for three-dimensional figures. They use manipulatives to model problems. Students create foldables and explain volume and surface area. Students complete worksheets and classify solids. Students sing a song about perimeter and area. They play a basketball game and use dice and cards to generate volume and area problems.
Students explore Earth science by creating a scale model in class. In this shadow lesson, students research the impact the sun has on Earth shadows and complete a space science worksheet. Students create models of the Sun and Earth and experiment with making fake shadows with three-dimensional objects.
Students examine the vocabulary that describes shapes and angles and make connections with the relationships that involve two and three dimensional objects. In this paper folding 2D and 3D shapes lesson, students work with a partner to fold paper while providing instructions. Students use communicative and mathematical language to express ideas correctly.
Tenth graders explore the concept of 3-D similarity of polygons. In this 3-D similarity of polygons lesson, 10th graders measure the lengths, widths, and heights of two boxes that students consider to be similar. Students work in groups to identify corresponding angles and sides among two 3-D figures.
Fifth graders explore geometry by participating in a group math activity. In 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.
Students explore the concept of congruent and similar figures. In this congruent and similar figure lesson, students classify pictures according to congruent and similar figures. Students measure the lengths of various figures to determine if they are congruent, similar, or neither. Students measure and compare the diagonals of various polygons such as parallelograms, rectangles, squares, trapezoids, and rhombuses.
