Describing an Object's Position
Learners explore language arts by participating in a shape identification activity. In this geometry shape lesson, students discuss the vocabulary terms used to describe the location of an object. Learners complete a worksheet based upon...
Curated OER
Midpoint of a Segment
Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.
Curated OER
Best Practices in Technology Integration
Students go through various construction techniques needed to bisect angles, lines and arcs, construct a perpendicular from a vertex to a line, construct the center of a circle, transfer an angle, and various other constructions normally...
Curated OER
Math: Equal Area Triangles
Young scholars examine a math worksheet and determine how to divide a single triangle into four of equal area. Using geometric principles, they sketch two additional ways to divide into into four equal triangles. To conclude, students...
Curated OER
Sort It Out and Match It Up
Young scholars identify objects that are the same shape and size. They compare and contrast attributes of two-and three-dimensional objects using appropriate vocabulary. Pupils justify an extension of a geometric pattern to explain...
Curated OER
Symmetrical Journals
Young scholars examine the concept of symmetry by studying the symmetry of symbols in a wall painting and creating journals with a symmetrical design. After a class review of symmetry and identifying the line of symmetry in several...
Curated OER
Straws and Shapes
Students investigate the concepts related to observing two dimensional objects. They also build three dimensional objects using the two dimensional objects. The students give an oral or written explanation for how the pieces fit together...
Curated OER
Building Paper Bridges
Young scholars construct a bridge that can hold 100 pennies. In this math instructional activity, students evaluate the strength of their bridges. They predict how much weight a bridge can hold based on its design.
Curated OER
Shape It
Fourth graders use math software and geoboard paper to design basic shapes. They write individual definitions for the geometric shapes based on what they see in the shapes. They apply their background knowledge of the shape as they write...
Curated OER
Geo Jammin By Design: The Important Thing
Students brainstorm what they know about geometric terms and patterns. They identify symmetry, shapes and congruency. They create a book of symmetry.
Curated OER
Ship Shape
Second graders explore shapes and create a Silly Shape book. Students recognize that shapes have certain properties and be able to define them. Example, a triangle is any three-sided shape. Students' job is to make a picture on...

An Introduction To Quadrilaterals
Young geometers investigate and apply properties of quadrilaterals. After a review and discussion of key terms, students use a computer applet to explore four-sided figures and classify them according to their attributes. 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...
Illustrative Mathematics
Points equidistant from two points in the plane
Young geometers apply their deductive reasoning skills and knowledge of proving triangles congruent in a task that asks them to prove if a point lies on the perpendicular bisector of a segment, then it is equidistant from the endpoints...
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.
Curated OER
Building Big and Strong
Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.
Noyce Foundation
Boxes
Teach your class to think outside the box. Scholars use the concept of equality to solve a problem in the assessment task. They determine how to use a scale to identify the one box out of a set of nine boxes that is heavier than the others.
Curated OER
Tiling the Classroom
Students see how to identify regular polygons, how to slide, turn and flip polygons, and why certain polygons tessellate better than others. Groups create a one foot square design to be used to tile the classroom. Great activity!
Bowland
Sundials!
Time to learn about sundials. Scholars see how to build sundials after learning about Earth's rotation and its relation to time. The unit describes several different types of possible sundials, so choose the one that fits your needs — or...
