Right triangles from 2,000 years ago? Learners investigate different right triangles found in the earthworks of the Hopewell people, a Native American culture that populated the United States from 200BC to AD 500. Learners apply concepts...

Students investigate, read, and discuss about other famous Afro-American leaders. Students compare/contrast slaves home, activities, etc. with that of Afro- Americans today. Students create a time line to post on the wall of Harriet's...

Investigate simplifying rational expressions. Learners define rational expressions, review how numerators and denominators are polynomials and complete several problems using a checklist to ensure they don't skip any steps. Work can be...

How can we find volume if it a shape isn't easy to measure? Investigate methods for determining this as the volume of regular and irregular objects is explored in several stations. Learners discover that when the standard formula for...

Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them. They make predictions that can be answered through scientific...

Students investigate the concepts of volume for rectangular prisms and spheres. They measure the volume of one balloon and then consider how many breaths it would take to fill the room with balloons. The rectangular prism being measured...

Middle and high schoolers investigate how to solve inequalities. The lesson has a good guide for taking pupils through a direct instruction of the concept. You can use counting tiles in order to help kinesthetic learners.

Students investigate the One-Tonne challenge, and work out how they could reduce their greenhouse gas (GHG) emissions by one tonne, through individual actions and by influencing other people.

Seventh graders investigate the characteristics of a time zone map. They read and interpret time zone maps. Students compare the time in various time zones. Students solve time zone problems.

Young scholars use problem-solving approaches to investigate mathematical content. They formulate problems from situations within and outside mathematics content. They warm up with a survey done by the teacher. Everyone uses practice...
