Curated OER
Reading Graphs
Students practice plotting functions on the Cartesian coordinate plane, see several categories of functions, including lines and parabolas, and read a graph, answering questions about the situation described by the graph

Using Polya's 4 Steps to Problem Solving
Ninth graders solve problems using Polya's 4 steps to problem solving.
Curated OER
Reading Graphs
Students plot functions on the Cartesian coordinate plane. They explore lines and parabolas. Students analyze graphs and answer questions about the information presented on the graph using an online program.
Curated OER
Cartesian Coordinate System
Young scholars explore the Cartesian coordinate plane and plot points on the graph. They interpret coordinates for a point from the graph and give the ratio of rise over run for slope.

A Matter of Proportion
Middle schoolers measure the relative heights of the mosaic giraffe and its trainer and compare their proportions to an actual giraffe and zoo trainer.
Curated OER
Scale Me Down
Students create scale drawings, and ultimately scale models, of real-world objects in this Math lesson about ratios, proportion, scaling factors, and cross products. The lesson includes ideas for cross-curricular extensions and is...
Curated OER
Egyptian Fractions
Sixth graders take a brief look at what is known about Egyptian Fractions. These are unit fractions - fractions whose numerator is one. We look at how fractions can be represented in terms of Egyptian Fractions. Finally we suggest a web...
Curated OER
Addends with Spiffy
Students solve single variable equations. For this missing addend lesson, students solve problems with missing addends. Students create a function box to help study numerical reasoning.
Curated OER
Graphing Real World Situations
Students solve linear equations using graphs. In this algebra lesson, students depict real life situation using lines and functions. They identify the slope, data and predict graphing behavior.
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

Measuring a Mummy Case
Students calculate the size of a mummy case and its contents using ancient Egyptian measurements.
Curated OER
Alternative Alphabet
Students determine and compare hieroglyph content and frequency to an alternative alphabet based on symbols that mimic sounds of the alphabet.
Curated OER
Measuring a Mummy Case
Middle schoolers practice how to calculate volume using mummy cases. They measure using ancient Egyptian, U.S., and metric systems. They explore how to convert measurements into different systems, and discuss ratios.
