Unit Perimeters and Areas
Pupils use Geometers SketchPad to find the area and perimeter of several shapes. In this geometry lesson, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are included with...
Curated OER
Mobius Band
Tenth graders discuss sides of a shape and how to collect data correctly. In this geometry lesson, 10th graders examine shapes and count the surfaces on the shape. They read the history of Mobius Band and relate it to surface area.
Curated OER
Coconut-Shell Cup
Students research and discuss the social ritual of drinking chocolate in viceregal Mexico. They explain its cultural and historical and geographical roots. Students create their own "drinking" vessel from papier-mache. They experiment...
Curated OER
Cultural Cups
Students create their own drinking vessel from papier-m??ch??. They experiment with different shapes for drinking vessels and different patterns for them.
Curated OER
Lines, Rays, Line Segments, and Planes
Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes
Curated OER
Bubble and Boyle
Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...
Noyce Foundation
Parallelogram
Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...
Mathematics Vision Project
Module 6: Congruence, Construction, and Proof
Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...
Curated OER
Pattern Block Fractions
Fourth graders participate in a lesson that is about the finding of different fractional sizes with the help of pattern blocks. They define the vocabulary terms of numerator and denominator. The lesson also uses geometry and relates it...
Shodor Education Foundation
Pythagorean Theorem
Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...
Noyce Foundation
Which is Bigger?
To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.
Inside Mathematics
Magic Squares
Prompt scholars to complete a magic square using only variables. Then they can attempt to solve a numerical magic square using algebra.
Inside Mathematics
Squares and Circles
It's all about lines when going around. Pupils graph the relationship between the length of a side of a square and its perimeter. Class members explain the origin in context of the side length and perimeter. They compare the graph to the...
Inside Mathematics
Sorting Functions
Graph A goes with equation C, but table B. The short assessment task requires class members to match graphs with their corresponding tables, equations, and verbalized rules. Pupils then provide explanations on the process they used to...
