Once learners realize what direct variation is, they see it's just a type of linear function. The lesson poses a general question that leads to the creation of the y = kx formula. The resource includes discussion prompts and ideas for...

Students participate in an activity to simulate direct variation. In this oil spills on land lesson, students participate in a simulation using toilet paper and vegetable oil to explore the characteristics of direct variation. They...

Students solve algebraic proportions. In this algebra lesson, students convert between fractions, percents and decimals. They solve problems using the distributive property.

Students solve problems using ratios and proportions. In this algebra lesson, students verify proportions, solve for the unknown and use real life scenario to model proportion.

Learners solve problems of ratio and proportions using hands on. In this algebra lesson, students vary the concentration of a fruit drink using parts of a ratio.

Can you tell how tall someone is just by looking at their feet? In this activity, young mathematicians measure their height, arm span, and foot size, graph their findings, and answer questions about how these measurements are related....

Programming a robot is a mathematical task! The activity asks learners to examine the process of programming a robot to vacuum a room. They use a coordinate plane to model the room, write equations to represent movement, determine the...

High schoolers observe relationships between quantities. Students complete activities for three different classes of levers. In groups, high schoolers build each type of lever. Students identify levers in their daily surroundings. High...

Over the course of three class periods, middle schoolers design an experiment to provide learner input to administration about which rock band to invite to play at school. They practice several random sampling exercises, all well...

Discover an inverse variation pattern. A simple lesson plan design allows learners to explore a nonlinear pattern. Scholars analyze a distance, speed, and time relationship through tables and graphs. Eventually, they write an equation to...

Show your classes the importance of mathematics in something as simple as bicycle design. The final lesson in the six-part STEM series has each group research a different aspect of the bicycle. Learners use mathematical formulas, linear...

Learners discover that proportions are made up of equal ratios each containing the same building blocks. They, using the Internet, apply their knowledge of direct relationships and proportions to problems in planetary science.

Learners create visuals of the effect of a spring scale. In this algebra lesson, students use the navigator to graph the effects created by a spring scale. They draw conclusion from the graph.

Students investigate speed, time and distance. In this algebra lesson, students utilize their knowledge of linear equations to solve problems related to time, speed and distance. This assignment is hands on using two toy race cars.

How high is too high for a belly flop? Learners analyze data to model the world record belly flop using a quadratic equation. They create a graph and analyze the key features and apply them to the context of the video.

Students calculate the volume of prisms and cylinders. In this geometry instructional activity, students are give part of the formula, and must calculate the missing parts. They use 80% accuracy for their dimensions.

Students explore the concept of chemical formulas.  In this chemical formula lesson, students watch a video about balancing chemical equations.  Students conduct an experiment using silver nitrate and sodium phosphate. ...
