Arithmagons
Fifth graders explore patterns and relationships among the numbers that form arithmagons. They create and attempt different rules that can be used to solve arithmagons. Students use linear algebra to solve arithmagons.
Curated OER
Geometry and Shapes
Fourth graders are asked to name different shapes.Four to five students to share their answers with the class. The teacher leads the discussion in geometry about the properties associated with shapes.
Curated OER
2-D Geometry
Third graders describe and compare attributes of two-dimensional shapes. They explain geometric terms, angles and shapes. Students demonstrate each vocabulary word with their body and they mirror the body positions associated with each...

Measurements
Seventh graders solve word problems involving real world situation. In this geometry lesson, 7th graders solve problems related to volume. They apply the formulas taught in geometry.
Curated OER
Review Geometry Week
Fifth graders participate in a review game of geometry topics. For this geometry lesson, 5th graders use the "Eggspert" interactive classroom game system to review the geometry skills taught that week. Students work in teams to complete...
Curated OER
Shape Capture Game
In this shape capture game learning exercise, 8th graders work in pairs to plot quadrilaterals, then guess ordered pairs for each other's shape in order to locate the vertices on the grid; can be used with other shape as well.
Curated OER
Equilateral Triangles
Students examine the attribute of equilateral triangles. For this equilateral triangle lesson, students examine a number of paper triangles to determine how they are classified. They determine how triangles are depicted in Navajo rugs.
Curated OER
Fitness
Fourth graders determine how to design regular and semi-regular tessellations of the plane. They develop the ability to demonstrate why a tessellation covers the plane in this series of lessons.
Curated OER
Math: A Geometric Neighborhood
Students, as a final project, draw a picture of their ideal neighborhood on a sunny day. In addition to the sun, their drawings include homes, trees, streets, and selected objects. Each object in their drawing has a written description...

Tango's Story
Fifth graders listen to "Grandfather Tang's Story" and use tangram pieces to create animals described by the main character.
Curated OER
Fractions of a Set
Third graders use fractions to describe part of a set. In this fractions lesson, 3rd graders are introduced to fractions through a book and use pattern blocks to describe a fraction as a part of a set. This lesson includes a scripted...
Curated OER
Geometry /Tessellations
Middle schoolers investigate the concept of tessellations and how they are formed using angles. They categorize how different patterns do and not tessellate and separate them into two different places for assessment. The teacher draws...
Curated OER
Angles and Parallel Lines
Sixth graders draw parallel and intersecting lines to observe and examine the characteristics of alternate interior angles, vertical angles, corresponding angles, and supplementary angles. Through observation, they discover the...

Geo Jammin' By DeSign - Day 2, Lesson 7: Start At Square One
Students examine new shape possibilities by combining two and four triangles using manipulatives.
Curated OER
Karen's Tiles
Students investigate how perimeter changes as area changes to see the relation between area and perimeter for similar shapes. They then students answer the question if the area of the rectangle increase, does its perimeter have to increase?
Curated OER
Foil Fun
Second graders be having hands-on experiences with three-dimensional solid shapes. They investigate the features of solid shapes and examine the names for them. They are introduced to making nets for 3D shapes.
Curated OER
Symmetry
Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...
Curated OER
Straws and Shapes
Students investigate the concepts related to observing two dimensional objects. They also build three dimensional objects using the two dimensional objects. The students give an oral or written explanation for how the pieces fit together...
Curated OER
Shapes are Everywhere
Second graders gain an understanding of geometric shapes and spatial reasoning. They learn the attributes of solid shapes in everyday activities. Students compare geometric shapes to everday objects, finding things that serve a purpose...
Curated OER
Sports Bag
Students determine an efficient layout of the pattern pieces needed to make a sports bag with given dimensions and specifications. Given a word problem, data set and a diagram, students evaluate the information they have available and...
Curated OER
Math: Equal Area Triangles
Students examine a math worksheet and determine how to divide a single triangle into four of equal area. Using geometric principles, they sketch two additional ways to divide into into four equal triangles. To conclude, students...

Peter's String
Students are introduced to the math problem and consider how they could approach it. In pairs, students investigate Peter's conjecture in any way they see fit. They then share their answers with the class.
Curated OER
Penny's Box
Students need to be able to calculate the volume and surface area of a cuboid as well as present a systematic list of results in order to justify the minimum case. The use of three factors of 100 is also important.
