Congruent Triangles - Is This Enough Information?
Seventh graders examine congruence postulates and apply knowledge to triangles in the world around them.
Curated OER
Someone Is In The Kitchen
Students investigate the lifestyles of the Native Americans and look at a recipe found on a website. They read the recipe and pay attention to the measurements. They differentiate between the various measures in order to apply them to...
Curated OER
Create A Question
Students explore mathematical problem solving. Given a case problem, students write a rule to solve problems involving decimal multiplication and division. They invent problems, share them with the class, and solve other student's...
Curated OER
Sunrise/Sunset
Students apply data from a weather-related website to predict patterns in the sunrise and sunset.
Curated OER
"If You Hopped Like a Frog" by David M. Schwartz
Students brainstorm several animal/personal scenarios, select one, and write out an explanation of the comparison. They apply the measurements/characteristics to themselves and use algebraic equations to demonstrate the comparison.
Curated OER
How Cool Is Your Environment?
Students study the formulas for calculating heat energy and how to convert Celsius to Fahrenheit. They apply the formulas on a worksheet.
Curated OER
Parks Design Project
Students explore two dimensional geometric figures. They explore the relationships and measurements of geometric figures. Students apply proportion and scaling. They design a city park for students and teenagers.
Curated OER
Tessellations: Use Angles To Show That Shapes Will or WIll Not Tessellate
Middle schoolers observe a selection of shapes. They identify which shapes will tessellate and justify their answer. Students apply the symmetry and angle properties of polygons to create tessellations.
Curated OER
Introduction to Density
Seventh graders define density in their own words. In this physics lesson, 7th graders solve density problems using its mathematical formula. They explain why some objects flow and some sink.
