Math in the Wetlands Field Trip
Get your class out in the environment for hands on math activities. In this wetlands lesson, learners transplant native plants, calculate how much soil is needed, and perform math activities based on this experience. They then make...
Curated OER
Indoor and Outdoor Patterns
Students explore geometry by participating in a visual illustration activity. In this pattern identification lesson, students explore inside their classroom and discuss patterns they find while tracing them on paper. Students attend an...
Curated OER
Everyday Objects with Shapes
Students explore geometric shapes. For this geometry and language development lesson, students take a walk and look for shapes in the objects outdoors. Students match each of four individual paper shapes they are carrying with the...

Measuring and Mapping the Playground
The school playground is a great place to learn about math. Pupils measure the dimensions of a playground using baby steps and individual strides. They use their measurements to create a scale drawing of the playground by applying an...

Catching the Perfect SAR Waves!
Zero in on an interesting resource involving radar technology. Groups construct a radar sensing unit and learn to calibrate the system. Using the radar system and the Pythagorean Theorem, they calculate distances between objects.

Handy Measuring Ratio
Your hand can be a handy tool for measurement. Young mathematicians learn how to estimate the height of objects by applying similarity. They find the horizontal distance from the object where spreading their outstretched fingers results...
Curated OER
Shadows and Skyscrapers
Eighth graders explain the relationship between the position of the sun, a city's latitude and shadow length. Ratio's, geometry, and algebra are used to determine the shadow lengths and building heights. A sun angle (altitude) charts to...
Curated OER
Indirect Measurement
Students measure and apply their knowledge of proportion to solve problems. In this geometry activity, students measure using a meter stick, small mirror and measuring tape. They compare and contrast their measurements to objects outside...
Curated OER
The Distance to an Unapproachable Point
Students use geometry or trigonometry to measure the distance of a far off point. They verify their measurements using a tape measure to check their work.

Vocabulary and Concept Development: EDI
The roots metro/meter and therm are the focus of a vocabulary building presentation that includes concise definitions, color-coded examples, and opportunities for guided and independent practice. Part of a series of roots and affixes...
Curated OER
Automobile-Accident Reconstruction
Students investigate an accident and relate it to math. In this trigonometry instructional activity, students measure the accident scene, the friction produced, and the speed from the skid marks. They create a poster of their findings.
Curated OER
It Counts
Students explore one to one number correspondence. In this early math activity, students make observations about and classify plants in order to gain an understanding of using numbers to describe their world.
Curated OER
Rubber Gardens
Students recycle discarded automobile tires and create gardening sites for limited space areas.
Curated OER
Shapes at Work
Students use their classroom to look for various types of shapes. In their science journals, they record the shapes they find and identify those that can be used to solve problems or build structures. They share and post their sketches...
