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.

Students are introduced to the concept of convergent infinite series using a recursive geometric construction. They explore the concept of a convergent infinite series using partial sums. Students use formal calculations, visualizations,...

Studnents examine the degree of biodiversity that exists in one's everyday environment, in order to develop an understanding of how scientists classify organisms and to explain why biodiversity is important for living things.

Ninth graders investigate the application of populations that exists in one's everyday environment, in order to develop an understanding of how mathematics is a key component in the understanding of population dynamics.

Students study rectangles. In this math lesson, students use numbers, measurements and geometry to draw rectangles of varying sizes.

Learners build polygons on their geoboards. In this geometry lesson plan, students build and then draw it on paper and label it. Learners then switch with a partner to try an make a symmetrical shape.

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.

Seventh graders explore basic geometric definitions involving angles, area, and circumference. To reinforce basic geometric concepts, they play a "lightning Flash" card game. Students discuss chores or jobs that require the use of...
