Geometry and Tony Smith Sculpture
Young scholars respond to Tony Smith's sculpture as art and brainstorm about math concepts inherent in his work. They create a sculpture with polyhedra nets, calculate the cost of covering sculpture in gold, and write an exhibit label...
Curated OER
How Long? How Wide?
Second graders distinguish between and use nonstandard and standard units of measurement, use appropriate tools and techniques to measure length and width, and record and interpret data using graphs.
Curated OER
Perimeter
Students examine the concept of perimeter. Students calculate the perimeter of a random shape on a grid. Students develop a better understanding of the concept of perimeter. Students calculate the perimeter of shapes.
Curated OER
Inching Our Way through Measurement
Students review how to use an inch ruler and listen to the story, Inch by Inch by Leo Lionni. In this measuring lesson, students work in small groups to create an Inch Poster. Students then use an inch ruler to measure different objects...
Curated OER
Measurements
Seventh graders solve word problems involving real world situation. In this geometry lesson, 7th graders solve problems related to volume. They apply the formulas taught in geometry.
Curated OER
Peter's String
Students are introduced to the math problem and consider how they could approach it. In pairs, students investigate Peter's conjecture in any way they see fit. They then share their answers with the class.
Curated OER
Totally Tessellations!
Eighth graders investigate the concept of tessellations and transformations. They create patterns to demonstrate and practice the skill. Students write a description of the pattern for others to interpret. The pattern is assessed...
