Slip Slide'n Away
Students analyze the sliding of boxes along a warehouse floor. In this algebra lesson, students connect math and physics by calculating the friction created by the sliding of each box. They develop faster method to move the box, based on...
Curated OER
Conjectures and Conclusions
Learners draw conclusions and make conjectures given a specific scenario. In this geometry lesson plan, students model real life scenarios using properties of triangles. They model number facts and explain why the outcome is what it is.
Curated OER
Conductivity of salt Solutions
Students investigate the concentration level of solutions. In this math/science lesson, students identify three different ionic compounds. They predict the conductivity of each using their collected data.

Translate Word Phrases and Sentences into Equations
Use this video to show your learners an example of how to translate word phrases into an equation to solve a real-world problem. The presenter begins with a review of how to use cross products to solve a proportion, including how to do...
Curated OER
Exploring Centers of Triangles
Students explore properties of triangles using angle bisectors, incenters, circles, midpoints, and altitudes. They use Geometer's Sketchpad in order to create triangles and their properties.
Curated OER
Light Beam
Students measure and convert between units. For this geometry lesson, students investigate through measurements of distances. They relate the properties of circle to solving problems with radius, diameter and area.
Curated OER
Direct Variation
In this Algebra II worksheet, 11th graders solve problems involving direct variation. The two page worksheet contains explanation, examples, and twenty-one problems. Answers are not included.
Curated OER
La Toteca- A Tropical Paradise
Students collect data on the time of the ferry. For this algebra lesson, students use the data to predict a ferry schedule. They also compute the depth where oxygen would be needed when diving.
Curated OER
What are the Odds
Students predict the-outcome of an event. In this algebra lesson, students compare and contrast the probability of an event occurring. They calculate the odds of a simple event and make estimation.
Curated OER
Looking For Triangles
Students solve problems with triangles. In this geometry instructional activity, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.
Curated OER
Wind, Pressure, Force, Calculus and Engineering Connections
Twelfth graders solve first order differential equations using the separation of variables technique. In this calculus lesson, 12th graders explain the connection between math and engineering. They brainstorm what engineers do in real life.
