Identifying Three Dimensional Figures (3)
In this 3 dimensional figures instructional activity, students study the 10 3-dimensional figures. Students identify and label each of the 10 figures.
Curated OER
2D Shapes (1)
In this shape recognition worksheet, students study each of the shapes and then write the names of the two-dimensional polygons on the lines.
Curated OER
Geometry Shapes
Students create various geometric shapes with their younger grade "buddy partners." They identify and discuss various geometric shapes, and using gumdrops or marshmallows and toothpicks, construct different flat and three-dimensional...
Curated OER
Volume and Surface Area: Which Is More?
Students explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...

Geometrically Artistic/Artistically Geomtric
Students identify the two-dimensional geometric shapes Lowrey utilized in the painting Untitled. Students compare the two-dimensional shapes in terms of equivalent fractions, congruency, symmetry and asymmetry. Students create their own...
Curated OER
Three Dimensional Figures
In this geometry worksheet, students study diagrams with labels of common geometric figures. Students then answer 24 questions. Then they draw and label their own figures.
Curated OER
Area Unit
Students solve the area for parallelograms,squares, rectangles, trapezoids, and triangles. In this geometry lesson, students compare and contrast two dimensional shapes and apply their properties to solving real life scenarios. This is a...
Curated OER
Exploration with Geometric Solids
Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.
