Boyle's Law and Charles's Law
In this gas laws worksheet, students complete 11 fill in the blanks and problem solving questions on Boyle's and Charles's laws.
Curated OER
Nested Similar Triangles
Nested triangles have been created so that they share a common vertex and vertex angle. Learners drag the endpoints of the side that is opposite the common angle to discover the conditions that make the nested triangles similar. When...
Curated OER
Triangle Midsegment
Learn how to calculate the length and midsegments of triangles. High schoolers differentiate between similar and congruent triangles. They create a spreadsheet with their findings.
Curated OER
Ratios of Similar Figures
High schoolers identify the ratios of different triangles. In this geometry activity, students identify the similarity and differences of triangles. They use the navigator to move the sides of the triangle around.
Curated OER
Not Everything is More Expensive
Students compare prices and determine percent increases and decreases of items in order to make wise purchases. In this percent increases and decreases lesson plan, students calculate the amounts based on grocery store ads.

Our community-in sculpture form
Students design tiles that represent their community. They discuss ideas with another class through email. They then create the tiles, fire them, and attach them to a masonite board to create a community mural.
Curated OER
Similarity and Congruence
Students determine that two figures are similar or congruent by
investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions,
postulates, and theorems.
