Finding Our Top Speed
Students determine the length of time needed to walk or run or walk a given distance. They plot the data on a graph and use the results of data collection to develop the concept of slope.
Curated OER
Equations of Lines
Learners define slope, and practice finding the slope of lines through given points. They determine the angle of inclination. Students find the relationship between the slope and the tangent of the lines. Learners determine special...

Systems of Linear Inequalities in Slope-Intercept Form -- Lecture
Students are introduced to linear inequalities in slope-intercept form. As a class, they participate when needed in a demonstration given by their teacher and practice graphing inequalities and describing the solution. They set up and...
Curated OER
How Low Can You Go?
Students are introduced to the concepts of elevation and slopes. Using Minneapolis and St. Paul, they graph elevation of various cities in a scenerio given to them. They also calculate the total miles traveled and organize the...
Curated OER
Mathematics Within: Algebraic Patterns
Students discover patterns in linear equations by playing a dice game to collect data. They graph the data and analyze the patterns of the lines created by the data. The class then compares the individual graphs to evaluate the position...
Curated OER
Track's Slippery Slope
Learners graph data of sports figure running time using x-axis y-axis to find slope of trend line, mathematically find the interpolated and extrapolated values for data points. Using the information they make predictions.
Curated OER
Slope Calculation
Students practice calculating the slope of a line. They explain how the formula is derived and identify properties that are associated with positive, negative and undefined slopes. They complete an online activity as well.
Curated OER
Explain the Change
Twelfth graders complete research relating to population changes in counties/states in the U.S. from 1900 to 2000 and use the slope formula to determine the overall change in population for each of the ten decades. They present their...
Curated OER
Step by Step
Students measure the rise and run of steps from a place that holds meaning for them. They write a reflection (in the form of a journal entry, poem, or short story) regarding this significant place.
Curated OER
Let's Graph It!
Students graph the height of others in centimeters and inches, find the slope of line in order to calculate the conversion factor between centimeters and inches.

High School Mathematics Problems from Alaska: Dog Lot Math
High schoolers determine the cost of feeding dogs during the winter and summer months when using commercially produced dog food.
Curated OER
High School Mathematics Problems from Alaska: Jesse Thomas Moose Hide Problem
Students solve problems about a student earning money for college by tanning moose hides.
Curated OER
High School Mathematics Problems from Alaska: Extensions of Data: Barrow, Alaska Sunrise/Sunset Information
Students using given data to extrapolate new information, using a linear equation to predict later behavior, and using previous knowledge to synthesize new conjectures.
Curated OER
STABLE ANGLES OF SLOPES
Students conduct an experiment using soil and shoeboxes to explore factors controlling and affecting the slope of a hillside. They analyze angles, surfaces, etc. to gain an understanding of instability of slopes.
Curated OER
Human Coordinate Plane
Eighth graders form a human coordinate grid to develop knowledge of the placement and meaning of coordinates on a grid. They experience the placements of the x and y coordinates in an ordered pair.
