8th Grade Math Common Core Checklist
Ensure your eighth graders get the most out of their math education with this series of Common Core checklists. Rewriting each standard as an "I can" statement, this resource helps teachers keep a record of when each standard was taught,...
Mathematics Assessment Project
Solving Quadratic Equations
Scholars first complete an individual assignment using a quadratic equation to model the movement of a bus around a corner. Learners then discuss their solutions with classmates and analyze the provided sample responses.

Over the Hill
Can you hear me from there? Pupils determine the place to build a cell tower on a hill. The class uses constraints and creates a scale drawing on a coordinate system to calculate the exact location of the base of the cell tower.
Radford University
Ramp It Up
Pupils gather measurements of real-world objects that have slopes. They then plot the measurements and find an equation of a line that fits the measurements. Finally, groups investigate the ADA and determine whether different ramps meet...

Seeing Shapes
Learners study a variety of geometric shapes by taking pictures of items representing the shapes with a digital camera. They identify the shapes by using software to paint on the image.
Curated OER
Math Hw #15: Proportions
In this proportions activity, students solve 8 word problems. Students determine the cost of an item given a unit cost. Students find a missing side length of a triangle using proportions of similar triangles.
Curated OER
Dizzy Heights
Fifth graders explore ways to measure the height of an inaccessible object. They measure lengths using a tape measure or ruler. Students measure angles using a protractor and estimate heights.
Curated OER
Amazing Consistent Ratios
Learners derive the six trigonometric identities. In this trigonometry lesson, students find the ratios of sine, cosine and tangent using the right triangle. They use properties of the Pythagorean Theorem to find the trig identities.
Curated OER
Unit 5: Worksheet 2 - Ratios
For this ratio worksheet, students investigate the relationship between the ratio of two sides of similar triangles. Afterwards, they convert fractions, decimals, and percents. This three-page worksheet contains approximately 35...

Introduction to Fractals: Geometric Fractals
High schoolers explore the concept of fractals. In this fractals lesson plan, students discuss Sierpinski's Triangle using an applet. High schoolers discuss the patterns involved with fractals. Students discuss the area of Sierpinski's...
Curated OER
Slope Right Up
Learners use triangles to find the length and slope of each side. After connecting the vertices, they add points based on their specific instructions. They use the Pythagorean Theorem to complete a worksheet to end the lesson.
Curated OER
Reflections
Students investigate image and pre-image. In this geometry lesson, students identify the reflection and rotation of different shape on a coordinate plane. They identify similarities and differences of image and pre-image of a reflection.
Curated OER
Primary Geometry
Students identity simple geometric shapes. In this early geometry lesson, the teacher introduces students to triangles, squares, and rectangles, then students identify and classify the shapes as they are found in the classroom. To...
