Metric Measurements
Sixth graders convert metric units of measurement. Classmates observe the use of a mnemonic for conversions. In groups, 6th graders practice converting metric units. They use a chart to describe how to convert between metric units of...

Pair 'Em Up!
Third graders verify the validity of Punnett squares. They simulate a real-world situation by drawing chromosomes from a paper bag and track the data.
Curated OER
The Process Of Addition
Students use manipulatives to explore the notation of addition and gain experience with independent practice. They demonstrate their knowledge by performing the operation on the board with magnets, on their own felt work mat then on...

The Mathematical Fingerprint of Our Solar System
Young scholars study the beautiful mathematical model unique to our solar system.
Curated OER
Measurement: Finding Areas of Rectangles
Students construct the formula for the area of a rectangle.
Curated OER
Sampling Snoops
Students practice formulating a hypothesis and designing an experiment to test the hypothesis. They identify several sampling techniques they can use to test their hypotheses.
Curated OER
Business Ownership
Students should identify and define the three basic forms of private business ownership.
Curated OER
50:50 Chances
Third graders reinforce the probability of gender by uising a coin toss, as they continue to search for the answers to genetics questions by using mathematical expectations of probability.
Curated OER
Observing the Evidence
Fifth graders explore how to do research from a large group. They explore how to choose a representative sample and collect data from it.
Curated OER
Old Poly Factoring
Students are given a set of Old Poly cards and then match polynomials to their factored forms in a game of Old Maid. They complete a worksheet for assessment.
Curated OER
Distance over Time
Students analyze velocity and how it is determined. They experiment with velocity in order to measure and calculate the magnitude of speed. They use examples in their novel "Skateboard Renegade" to relate velocity to real life situations.
Curated OER
Learn the Shapes
Students examine and identify the similarities and differences of two-dimensional shapes. They play an I-Spy shape game, participate in a classroom Shape Search, and create illustrations of shapes for a shape collage.
Curated OER
Relating Division and Subtraction
Third graders relate the process of division to subtracting equal groups. Through guided practice and teacher demonstration, they complete division problems using a subtraction method. Students complete problems independently for...
Curated OER
Opportunity Cost
Students study what opportunity cost is and why it is important to their lives.
Curated OER
What Are We Listening To?
Students gather data from a web site on number of music albums sold by genre for the last two years. They convert these figures to fractions, decimals, and percents, and display the results in bar graphs and pie charts.

Introduction to Mendelian Genetics using Fiction
Students investigate Mendelian Genetics by studying the history of Mendel and what it was like to be a 19th century scientist. They read a pieces of fiction during this investigation.
Curated OER
Are We There Yet?
Students continue to study rhyming words. They use words and illustrations to help develop their vocabulary.
Curated OER
Measure Mania
Pupils measure their own silhouette using Unifix cubes. They measure a drawing using non-standard measurement. They swap drawings and compare their measurements.

Investigating Segments in a Right Triangle
High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...
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
Circumscribing a Circle About a Triangle
Pupils circumscribe a circle about a triangle. They construct a triangle using Cabri Jr and then circumscribe it. They then use knowledge of perpendicular bisectors and circumcenters to locate the center of the circle and then...
