Proof with Parallelogram Vertices
Geometric figures are perfect to use for proofs. Scholars prove conjectures about whether given points lie on a triangle and about midpoints. They use a provided dialogue among fictional learners to frame their responses.
Bowland
Magic Sum Puzzle
Learners discover the magic in mathematics as they solve numerical puzzles involving magic sums. They then make a conjecture as to why no additional examples are possible based on an analysis of the puzzles.

The Sum of Our Integer Intelligences
Young mathematicians explore integers. They review adding integers through engaging in mathematical labs. Each lab station is designed to reflect one of the multiple intelligences. Resources for all activities are provided.

Castles On The Ground (2D & 3D Shapes)
Explore the relationship between 2D and 3D shapes by having your class view representation of shapes and investigate their symmetry. They will create a solid object from diagrams and describe the reflection or rotational symmetry. In the...

Games for Probability: In-Class and Powerball Simulation
Your soon-to-be statisticians play a game to understand the difference between independent and dependent experiments and probability. They draw colored cubes from a bag and then, by either replacing the cube in the bag, or not, for each...

Rotation
Rotate this resource into your lesson plans. Scholars rotate polygons in the coordinate plane by multiples of 90 degrees. They then compare the original and new figures to develop conjectures about coordinate points after rotations.
Curated OER
Matrix Transformations
Students perform reflections of polygons. In this algebra instructional activity, students use matrices to calculate the reflection across the x and y axis. They also calculate rotation representing 90 and 180 degrees around the origin...

Ducklings
The class gets their mean and median all in a row with an assessment task that uses a population of ducklings to work with data displays and measures of central tendency. Pupils create a frequency chart and calculate the mean and median....
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.

Justifying Mathematical Conjectures
Sixth graders, in groups, explain why they think something. This requires students to listen to and respond to each other. In this particular lesson, 6th graders explain to their classmates when one can or cannot construct a specific...
Curated OER
Reflections
Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...
Curated OER
Radical Transformations
Students transform the square root function graphically. In this transforming the square root function graphically lesson, students use their Ti-Nspire to change the a, b, and c values of th square root graph. Students transform the...

Modeling Drug Assimilation in the Human Body
Students investigate the accumulation of drugs in the body. In this algebra lesson, students collect data on drug retention and assimilation. They use their data to predict the behavior and effects of drugs.
Curated OER
Transformations
Tenth graders recognize, perform and derive rules for basic transformations including translation, reflection and rotation. They also consider compositions, a combination of two or more basic transformations. Students explore both...
