Curated OER
Number Prefixes
Students recognize the number prefixes used throughout the English language. They identify the shapes and the prefixes that are associated with them.
Curated OER
Probability and Geometry
Students practice calculating probability, see how geometry can help solve probability problems and explore platonic solids.
Curated OER
Shapes with Sticks
Third graders investigate three dimensional shapes. They examine a variety of shapes and the relationship between the number of faces, edges, and vertices. Students determine Euler's formula and they create a variety of three dimensional...
Curated OER
Euler Characteristic
Students identify the different properties of Euler's Characteristics. In this geometry lesson, students identify the shape and surface a polygon. They relate the concept of Euler to solving real world problems.
Curated OER
Space Tiling with Captain Planet
Fifth graders Apply the symmetry and angle properties of polygons, using symmetry and angle properties of polygons to solve practical problems. They study tessellates and explain why a shape tessellates.
Curated OER
Pyramids & Prisms: Guler's Formula
Sixth graders compare and contrast two-dimensional shapes to three-dimensional shapes. After watching a demonstration, they make their own shapes using nets printed on paper. To end the activity, they use the shapes they made and...
Curated OER
Pape's Theorems
In this math worksheet, students find the length of the side of a regular hexagon whose area is numerically equal to its perimeter.
Curated OER
Searching The Word
Fifth graders review EOG math terms and definitions found in their math notebooks, and pick between 15 and 20 words to put in a word search.
Curated OER
Building With Triangles
Fourth graders use two different techniques to construct triangles with specific dimensions. They determine how to construct nets for three-dimensional objects focusing on those made with equilateral triangles. They are able to name the...
Curated OER
2D Polygons and 3D Nets
Students compare and contrast two dimensional polygons and three dimentional nets by examining the differences in drawings. They create three dimensional shapes and label the faces, edges, and vertices. After creating the shapes, they...
Curated OER
Platonic Solids
Students identify different types of polygons. In this geometry lesson, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.
Curated OER
Examining Geometric Solids
Students explore geometry by completing a math worksheet in class. In this shape identification lesson, students identify the characteristics associated with 15 solid geometric shapes. Students identify patterns between vertices, edges...
Curated OER
Mirror Wells
Students study mirror wells, which are similar to 3-D kalediscopes, but the end is cut off to enable you to look at patterns through them.
Curated OER
Just One!
Learners play a trading game using Base 10 blocks that incorporates decimal place value. Then they each receive a paper with a decimal number on it and must arrange themselves in a line from least to greatest.
