Symmetry of Road Signs
Students identify symmetry in road signs. In this geometry instructional activity, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.
Curated OER
Shapes
Fifth graders explore shapes. They recognize and name two-dimensional and three-dimensional shapes. Pupils discuss the properties and criteria for each shape they find in real life and construct a Kid Pix project using pictures of the...
Curated OER
Exploring Perimeter
Students explore perimeter. In this geometry and measurement lesson plan, students create squares and rectangles using given perimeters. Students construct four sided shapes with given perimeters using the computer program "Math Keys:...
School Mathematics Project
Resource Sheets
This extensive and far-reaching collection of worksheets puts a new twist on many basic concepts. Learners use multiplication to trace a path from one point to another, tile a plane by converting between improper and proper fractions,...

Global Positioning System II
Intricate details of a modern technology that many of us take for granted in our phones, computers (and some cars) are laid bare in a short but deeply investigative activity. The math behind a seemingly simple GPS device...
Curated OER
Shapes
Learners participate in a number of hands-on shape-related activities. They match and sort shapes by attribute, read books about shapes, complete shape art projects and explore and compare parts of shapes.
Curated OER
Eating Patterns
Students sort through pictures of food to create patterns as they pertain to geometry. In this geometric patterns lesson, students relate to food as concrete objects that represent geometric patterns. Students recognize and...
Curated OER
Scale Drawing
In this geometry worksheet, students use the correct units to measure distance, length, diameter and height. There are 8 questions with an answer key.
Curated OER
Mathematical Diagrams
In this geometry instructional activity, students figure out the distance between 2 cities using the distance formulas. They apply flow charts to their problems and solutions to identify and clarify their steps. There are 40 questions.
Curated OER
Areas and Perimeters
In this geometry worksheet, 10th graders are given polygons on a coordinate plane. They calculate the area and perimeter of each shape, by counting the length of each square on the graph.
Curated OER
Exploring Special Lines
Students compare and order numbers. In this geometry lesson plan, students write equations for inequalities. They differentiate and apply concepts of triangular properties to solve problems.
