Description

In this application of arithmetic concepts, students analyze the changing population of bison in the Americas. Using real-world data and applying key math concepts, students will do some sophisticated analysis using basic skills. 

These are the key math concepts covered:

• Place value
• Skip counting
• Doubling
• Data analysis

Given the wide disparity in the population of bison over several centuries, students will be analyzing data in the millions but using place value to gain a clear understanding of the numbers involved. Skip counting will be used to analyze changes to populations, including patterns than involve doubling.

Students will be actively engaged with the subject matter and will develop a mathematical mindset around data. This is an excellent preparation for the data analysis developed in upper elementary and middle school.

Description

In this module, students analyze the geometric properties of road signs. This includes studying triangular, quadrilateral, and other polygon forms in such familiar signs as the stop sign, the yield sign, and many other examples.

Students then study the non-geometric properties of these signs, specifically the color coding developed by the US Department of Transportation. This provides a real-world application of geometric concepts.

Geometric topics covered include:

• Properties of equilateral and isosceles triangles
• Properties of quadrilaterals, specifically rectangles and squares
• Properties of other polygons

Finally, students combine their understanding of the geometric and color-coding used with signs to analyze specific road signs using critical thinking and logical reasoning. Your student s will be highly engaged by this study of roadside geometry.

Description

In this module students analyze real-world data relating to apple production and consumption. Looking at global and US data, students look at measures of central tendency by analyzing a box-and-whisker plot and later normal distribution graphs.

Math topics covered include:

• Median
• Mean
• Box-and-whisker plot
• Normal distribution
• Sample mean and sample standard deviation

This module includes three videos that provide examples, definitions, and real-world context. Supplement this module with hands-on activities where students calculate their own data from random samples. 

Description

In this module students use their geometry and algebra skills to analyze a wildlife refuge in Nevada. Calculating the area, perimeter, and the ratio of the two allows students to analyze different configurations for a refuge. Specifically, they look at ways of designing a wild horse refuge, using the concepts they have learned. 

Math topics covered include:

• Rectangle area and perimeter
• The ratio of perimeter to ratio
• Analyzing the graphs of area and perimeter equations (graphs of linear and rational functions)
• Solving real-world design problems

This module includes three videos that provide examples, definitions, and real-world context. Your students will also learn a great deal about environmental concerns related to wildlife refuges.

In this module, review key vocabulary for fractions. The focus is on the properties of fractions and understanding what a fraction is and how to represent it. There are various ways of representing fractions, as well as different types of fractions. Specific terms covered include:

• Fraction
• Numerator
• Denominator
• Fractions in Simplest Form
• Proper Fraction
• Improper Fraction
• Mixed Number
