Chopping Cubes
Middle schoolers work in small groups to make various geometric solids with Play-Doh. They use fishing line to make cuts and observe the shapes of the cross-sections. Pupils complete an assessment in which they answer questions such as:...
Curated OER
Pyramids on Parade/Nets
Students sketch the shape of three dimensional pyramids using nets. In this geometry lesson, students differentiate a pyramid from other three dimensional shape. They define the attributes of pyramids.
Curated OER
Sketching Spheres
Students investigate spheres through sketches. In this geometry lesson, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.
Alabama Learning Exchange
Understanding Fractions
Young learners explore fractions and demonstrate parts of a whole by using a candy bar and a piece of paper and dividing both into equal parts. Included is a worksheet that requires youngsters to color in half of each polygon shape. Some...
Curated OER
Math: Symmetry and Similarity
Students describe the differences between congruence and similarity. After explaining the motions that indicate congruency of two shapes, they complete worksheets to draw lines of symmetry and similar shapes. With straws and twist...
Curated OER
Sketching Cylinders
Young scholars create nets of cylinders. In this geometry lesson, students calculate the surface area of cylinders and other solids. They show their understanding of three-dimensional shapes by solving problems.
Curated OER
Sketching Prisms
Students sketch and create nets of different polygons.In this geometry lesson, students differentiate prisms from other three-dimensional shapes. They define the properties of prisms.
Curated OER
How Volcanoes Grow
Students build models of the three major types of volcanoes and see how a volcano's shape is related to the type of material it erupts. As a class, they observe a demonstration that simulates the nature of two volcanic materials: lava...
Curated OER
Pyramids with Basic Bases
Students explore pyramids. In this math lesson, students discuss where they have seen examples of pyramids. Students classify pyramids as three-dimensional figures and identify their attributes.
Curated OER
Electronic Geometry Notebook
Students examine the relationship between two and three dimensional shapes. They use their drawings to solve problems. They create a notebook of the formulas and how they relate to the real world.
Curated OER
Quilting
Learners use a monochromatic palate, select shades and tints for a selected hue, or select complimentary or analogous colors for a quilt design. They design quilt squares using basic geometric shapes, repetition, balance, and proportion.
Curated OER
Looking at Circumference
Young scholars understand where the number for pi comes from. They understand and use the formula for circumference. Students measure the circles given out and the diameters of those circles and record the results on their worksheet.
