Just what does it take to show two rhombuses are similar? The assessment task asks pupils to develop an argument to show that given quadrilaterals are rhombuses. Class members also use their knowledge of similar triangles to show two...

Witness the power of exponential growth with an activity that investigates two different savings plans. Class members create tables of values to see how and when a savings plan increasing exponentially exceeds one increasing linearly.

Don't let a little challenge get between your pupils and their learning! Scholars compare two absolute value functions to recognize patterns and use them to build their own functions with outputs that are between the given. They then...

That's the ticket! Pupils write and investigate two linear functions representing the cost of printing tickets. Individuals then determine which of two printing companies would be a better buy.

Design an efficient cereal box. Scholars use set volume criteria to design a cereal box by applying their knowledge of surface area to determine the cost to create the box. They then determine whether their designs will fit on...

Not all resources are created equal — and your class benefits! Scholars learn how to solve one-step inequalities using inverse operations. They complete an activity matching inequalities to their solutions.

In this statistics and probability worksheet, young statisticians solve and complete 13 different problems related to probability, percentages, and normal distributions. They consider data models, assumptions about the models, and find...

More than 90 percent of the people in a building have come down with an illness, and it is your job to investigate. Teachers give scientists the data needed to decide what is important and how they can solve the mystery....

Scholars apply the concepts of box plots and dot plots to summarize and describe data distributions. They use the data displays to compare sets of data and determine numerical summaries. 

Move on into trigonometry. An informative eBook takes the content of a College Algebra course and adds more relating to trigonometry and trigonometric functions. The content organization allows pupils to build upon their learning by...

Students map and describe small area of the schoolyard and discuss habitats.

Life's not fair, but decisions can be. The 17th installment of a 21-part module teaches learners about fair decisions. They use simulations to develop strategies to make fair decisions.

Elementary schoolers are arranged in pairs and view the video Math Works: Measurement: The Difference Between Perimeter and Area. They discuss any prior knowledge they have of the term perimeter and then brainstorm together what the...

Is there a correlation or causation relationship between air pollutants? Groups develop a hypothesis about the daily variation of air pollutants, specifically ozone and CO2. Using Excel to analyze the data, the groups evaluate their...

Representing data is as easy as pie. Class members construct pie charts given a frequency table. Individuals then determine the size of the angles needed for each sector and interpret the size of sectors within the context of frequency....

Is there more to college algebra than this? Even though the eBook is designed for a college algebra course, there are several topics that align to Algebra II or Pre-calculus courses. Topics begin with linear equation and inequalities,...

Students explore scientific graphs and charts. They describe the origin of power curves and examine QC procedures. Students calculate critical-size errors that are medically important. They read OPSpecs charts. Students describe the...

Students are able to calculate the population density of a country, and calculate the population density of large cities in that country. They are able to create an appropriate graph to represent their data for that country.

Eighth graders experiment to determine the number of drops of water a heads up penny hold. They create a stem and leaf graph of the class results and use the data for further experimentation on a tails up penny.

Students view a video about Galileo's discoveries. They work together to create graphs showing the current sunspot cycle. They discuss how sunspots can cause communication devices problems.

Young scholars interpret a variety of motion graphs. In this physics lesson, students calculate the speed and acceleration of objects using numerical data from graphs. They apply what they have learned to solve real world problems.

Sixth graders read about and study motion. They conduct a lab in which they calculate speed using track records at their school. They graph the results and then invite a guest speaker (an officer from the local police department) who...

Students demonstrate their understanding of math skills. In this data analysis lesson, students complete a worksheet requiring them to calculate mean, median, and mode, and create and interpret graphs. Lesson is intended as an assessment...

Students determine statistics based on data.  In this statistics lesson, students use data and record in charts.  Students create graphs based on the statistics found.
