Arithmetic Series, Geometric Series, Partial Sums of Geometric Series
In this Algebra II/Pre-calculus worksheet, learners solve problems that involve arithmetic series and infinite geometric. Students determine the partial sums of a geometric series. The three page worksheet contains forty-six problems. ...
Curated OER
Traveling Through the Solar System
Students use calculator and non-calculator methods for analyzing data. They apply data collection and analysis in a study of mass and weight. Students enhance and apply the concept of line of best fit. They master graphing in a plane,...
Curated OER
Meet the Neighbors: Planets Around Nearby Stars
Learners explain why a transiting planet causes a periodic dimming in the light from its parent star. They determine the radius of a planet, and its orbital distance, by analyzing data and manipulating equations. Students compare the...
Curated OER
What's My Pattern?
Students recognize, describe and extend patterns in three activities. They organize data, find patterns and describe the rule for the pattern as well as use the graphing calculator to graph the data to make and test predictions. In the...
Curated OER
Percentages in Word Problems
Eighth graders, after brainstorming all the places they see percentages in every day life (sales, basketball, grades, etc.), calculate percentages from bases and parts in word problems. They review their notes together on percentage...

Turtle Tales
Students watch videos and fill out worksheets about the turtles and their journey to the Costa Rican beach. In this turtles lesson plan, students learn and discuss survival, predator and prey, and stages of development.
Curated OER
Pythagorean Theorem
Eighth graders use formulas to solve Pythagorean Theorem problems. They explore the hypotenuse, adjacent angles and legs of a triangle. Given any two integers in a problem, 8th graders identify and complete Pythagorean triples.
Curated OER
Addition With Integers
Eighth graders investigate the concept of combing integers using addition. They begin to comprehend the connection of addition and subtraction. Students also review the concept of positive and negative numbers.
Curated OER
Describing Patterns
Fourth graders investigate repeating and growing patterns. Models, graphs and words are used to describe, extend and represent patterns. Students use evidence from models and graphs to support the identification of patterns.
Curated OER
I Can Do This! Systems of Equations
Students solve systems of 2-by-2 linear equations using tables,
graphs and substitution. In small groups, classmates work together to discover strategies for solving equations. They use a calculator to graphically represent their answers.
Curated OER
Super Sort
Students sort objects based on one characteristic. They define the term "attribute" and give examples of attributes of objects. Students explain their reasoning for sorting objects into groups.
Curated OER
Translations, Reflections, and Rotations
Tenth graders have been introduced to the concepts of translation, reflection, and rotation, and have practiced translating, reflecting, and rotating two-dimensional objects on the coordinate plane.
