Curated OER
Walking Math into the Real World
Middle schoolers measure an area given a yardstick. They also convert inches into a fractions of a foot and use data to create a linear graph.
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
A Thanksgiving Survey
Students take a survey then use the information gained from the survey to help plan a typical Thanksgiving dinner for our last day of class. They create a graph which corresponds the the data gathered during interviews.
Curated OER
Code Breakers
Students collect data and make a frequency table, change ratios into percents, and analyze data to make predictions.
Curated OER
Properties of Fractals
Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...
Curated OER
Practicing Arithmetic
Students practice single operation arithmetic ranging from single digit addition to long division of decimals or real numbers using Graphit. They use data sets and rules to graph ordered pairs.
Curated OER
Properties of Fractals
Young scholars build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by...
Curated OER
Irregular Fractals
Middle schoolers study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.
Curated OER
Linear Progression
Students use graphing calculators to graph lines and create tables of values. They perform an experiment using M&M's and slinkys, then create their tables based on their results.
Curated OER
Exploring Gear Trains
Students work together to build a simple gear train. They record their observations as it gains speed and how the gears rotate. They develop rules about gears based on these observations.

Illustrative Mathematics: G Gpe a Midpoint Miracle
In this task, students are asked to draw a quadrilateral so that no two sides are congruent, no two angles are congruent, and no two sides are parallel. The task gives students the opportunity to prove that if we join the midpoints of a...
