Exponent Power
Learners explore multiplication and division problems using exponents. Students examine positive, negative and zero powers. They relate powers to geometric sequences. Learners devise strategies and discover rules of exponents.
Curated OER
Linear Systems
In this multiplication of vectors worksheet, students prove that the dot product operation is commutative. They normalize a vector so it has the same direction with a magnitude of one. Students use the angle formula to confirm...
Curated OER
The Official Quilt of Alabama- The Pine Burr Quilt
In this quilting worksheet, students follow the directions to re-create the official quilt of Alabama, The Pine Burr Quilt. They use geometric shapes and stitching directions to make quilt squares.

Fold and Cut 2
Second graders make, name, and describe, using their own language and the language of geometry, everyday shapes and objects. They create and discuss geometric patterns which repeat (show translation), or which have rotational or...
Curated OER
Can Stack
Learners are able to find the rule for summing consecutive numbers;
identify the pattern of triangular numbers. They then solve the given problem using logic and mathematical reasoning.
Curated OER
Sequences and Exponents
Students practice multiplication sequences and multiplying with exponents. They study how a sequence is a set of numbers which follows a mathematical rule and can be used with all four operations and with combinations of operations.

Learners examine patterning in Chinese and Japanese artwork prior to creating their
own tessellations using styrofoam plates in this creative cross-curricular lesson for upper-elementary/middle level classrooms.
Curated OER
Sort It Out and Match It Up
Students 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 what was...
Curated OER
Irregular Fractals
Students study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.
Curated OER
Turn Symmetry
Fourth graders observe geometric patterns to determine if they show rotational or point symmetry. They participate in the a demonstration lesson with a triangle. They create their own designs that show rotational or point symmetry.
Curated OER
Geometry Scavenger Hunt
Learners use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings
