Evaluating Casual Claims
Responsible decision making relies on the ability to a recognize, analyze, and evaluate claims. The worksheets and activities in this 32-page packet teach learners how to distinguish among opinions, reasoned arguments, facts, and logical...
NASA
Applying Newton’s Laws
Newton's Laws get the rocket to work, but do they serve any other functions? A six-page resource classifies rockets by the type of propellant they use. It then describes applications of Newton's Laws of Motion, both in the...

History / Introduction of Pythagorean Theorem
Learners explore Pythagoras and the history behind his theorem. They work together to solve a proof that is embedded in the lesson.
Curated OER
Fraction Animals
Second, third, and fourth graders explore fraction strategies and division by splitting sets of farm animals into equal numbers. Independently, they read word problems, solve them, and check their answers.

Maxima and Minima Problems
Students calculate the maxima and minima of quadratic equations. In this calculus lesson, students apply the derivatives by finding the maxima and minima using real life application. They solve optimization using the derivative.
Curated OER
Navigating by the Numbers
Students observe how math is important in navigation and engineering. They study how surveyors use math and science to calcute, count, measure, label, and indicate distances on a map. They estimate specific distances.

Kids Conserve? Water Preserved
Students study conservation and how cities obtain their water. In this water lesson plan students view a PowerPoint presentation and draw a picture of the water cycle.
Curated OER
Using Density to Identify Metals
Students learn how to measure the density of metals. In this density of metals lesson plan, students measure the density of various metals in order to determine what metals were substituted in a king's crown, scepter, breast plate and...
