Coffee
There are many ways to correlate coffee to life, but in this case a worksheet looks at the price of two different sizes of coffee. It requires interpreting a graph with two unknown variables, in this case the price, and solving for those...
Curated OER
The Mandelbrot Set
Students are introduced to the notion of a complex number and function iteration in order to motivate the discussion of Julia sets and the Mandelbrot set.
Curated OER
Optimization For Breakfast
Students identify he proportion of a cereal box. In this algebra lesson, students define the relationship between patterns, functions and relations. They model their understanding using the cereal box.
Curated OER
The Tipping Point
Students rewrite word problems and solve using math. In this word problem instructional activity, students gather data and observe the data. They relate this process to the scientific method and math. They review their data to be able to...
Curated OER
One, Two, Three...and They're Off
Students make origami frogs to race. After the race they measure the distance raced, collect the data, enter it into a chart. They then find the mean, median, and mode of the data. Next, students enter this data into Excel at which time...
Curated OER
The Mandelbrot Set
Young scholars explore the Mandelbrot Set. They are introduced to the concept of a complex number and function in order to motivate the discussion of Julia and Mandelbrot sets. Students investigate fractals and how they are built.

Properties of Angles, Lines, and Triangles
In this properties of angles, lines and triangles instructional activity, 10th graders solve and complete 28 different problems that include determining the measurement of various figures shown. First, they use the geometric properties...
Curated OER
Impossible Graphs
Students distinguish between possible and impossible graphs of functions, and to learn why some graphs are impossible. They have practiced plotting functions on the Cartesian coordinate plane
Curated OER
You Can Count on Squares!
Fourth graders engage in and explore to develop mathematical, specifically algebraic, ideas. Although the tasks are built around measurement, they are algebraic to the extent that they require 'formulae' to be derived form the geometric...
Curated OER
Recognizing Patterns
Students explore the concept of patterns. In this patterns instructional activity, students use applets to manipulate tessellations. Students predict the next number in a sequence by recognizing patterns.
Curated OER
The Quadratic Formula
Students solve quadratic function by completing the square. For this algebra lesson, students use the quadratic formula to factor quadratics and find the roots. They graph the parabola and identify its properties.
Curated OER
Exploring Arrangements of 2, 3, 4, and 5 Cubes
Students use problem solving skills to create various models of tricubes, tetracubes, and pentacubes. They classify the cubes into various groupings and identify them as mirror images, regular arrangements, and irregular arrangements....

Collecting the Rays
Students investigate the affect shape has on the ability of a solar panel to collect sunlight. In this collecting sunlight using a solar panel lesson, students determine which solar panel shape collects the most sunlight. Students use...
Curated OER
Tilted Squares and Right Triangles
Students investigate squares. They generate patterns from structured situations and find a rule for the general term and express it using words and symbols. Students generate patterns from a rule and substitute values and formulas.
Curated OER
The Swinging Pendulum
Students observe a pendulum and graph their observation. In this algebra lesson, students use the TI calcualtor to graph the motion the pendulum makes. They analyze the graph and make predictions.
Curated OER
Graphs and Functions
Students are introduced to plotting functions on the Cartesian coordinate plane seen several categories of functions, including lines and parabolas
Curated OER
Exploring Arrangements of 2, 3, 4, and 5 Cubes
Students construct models of various tricubes, tetracubes, and pentacubes that are possible, classify n-cubes into different groupings, and draw these figures on isometric dot paper giving true perspective to what they visualize.
Curated OER
