About Media4Math

Our Mission

Media4Math's mission is to educate 21st-century students in real-world applications of math with digital technology. We bring math to life in your classroom with a rich blend of resources to inspire your students to learn. Our philosophy is that the procedural side of math is a prerequisite to using it, but we also find that real-world math applications can provide motivation and even inspiration for math students. Math is its own language and it has important stories to tell. While many of our resources are for procedural skills, there are many resources that are real-world applications of math. Some of these resources rely on partnerships with other educational publishers.

About Media4Math Classroom

Media4Math Classroom provides ready-to-use interactive math lessons that teach, assess, and provide real-world applications of topics in Pre-Algebra, Algebra, and Geometry. Assign these modules to your students and capture assessment scores in an easy-to-use Dashboard. This is a growing library of instructional modules. Topics include:

Arithmetic
Pre-Algebra
Algebra
Geometry
SAT Math Prep

Media4Math Classroom modules provide real world applications of math that will motivate your students. Here are some examples:

Construction Site Math. Apply ratios and proportions to mixtures of cement and concrete. This module includes video resources and your students will get a real-world application of ratios and proportions.
Counting Bison. Apply place value concepts to the real-world application of the bison population. Because the bison population has gone through dramatic changes in population, this become an opportunity to use and apply place value.
Wildlife Refuge. This study of area and perimeter centers on the mustang population in the Nevada area. Students explore the relationship between area and perimeter of rectangular shapes in the context of designing a wildlife refuge.
