The Illustrative Mathematics Project provides guidance to states, assessment consortia, testing companies, and curriculum developers by illustrating the range and types of mathematical work that students will experience in a faithful implementation of the Common Core State Standards, and by publishing other tools that support implementation of the standards.

In this interactive activity adapted from Annenberg Learner's Teaching Math Grades 6–8, explore some of the ways graphs can represent mathematical data contained in a story.

This course is intended to assist undergraduates with learning the basics of programming in general and programming MATLAB in particular.

This learning video addresses a particular problem of selection bias, a statistical bias in which there is an error in choosing the individuals or groups to make broader inferences. Rather than delve into this broad topic via formal statistics, we investigate how it may appear in our everyday lives, sometimes distorting our perceptions of people, places and events, unless we are careful. When people are picked at random from two groups of different sizes, most of those selected usually come from the bigger group. That means we will hear more about the experience of the bigger group than that of the smaller one. This isn't always a bad thing, but it isn't always a good thing either. Because big groups ''speak louder,'' we have to be careful when we write mathematical formulas about what happened in the two groups. We think about this issue in this video, with examples that involve theaters, buses, and lemons. The prerequisite for this video lesson is a familiarity with algebra. It will take about one hour to complete, and the only materials needed are a blackboard and chalk.

This is an activity that makes math real. The students complete some activities that show the length of a wheelchair ramp is determined using American Disabilities Act.

This lesson will allow students to build their own balloon car racer as an introduction to engineering and coding.  Each pair or team of students will be able to engineer their balloon car, measure the performance of their cars using yard sticks, and set up a basic algorithm to construct and run their machine.PURPOSEThe goals for this lesson are to: (1) integrate engineering and coding to young students; (2) have students independenty identify the steps (an algorithm) to build and improve their racers; (4) be able to spot "bugs" in their algorithm; (3) integrate measurement and addition operations to determine which car went furthest overall; and (4) teach perserverance by showing students that it is normal to find bugs in algorithms/coding.   

Reimagining mathematics instruction can be a heavy lift. Most teachers have years of traditional mathematics instruction under their belts by the time they enter their professional careers. Chapter 4 of  EL Education’s book Learning that Lasts explores two critical strategies for improving mathematics instruction—changing mindsets about mathematics; and remodeling the basic lesson structure for mathematics. This reimagination leads to mathematics instruction that is more challenging, engaging, and empowering for students as well as teachers.

The earth’s atmosphere may seem thick when compared to something like your height—but it’s surprisingly thin when compared to the earth’s radius. Here, you can find out exactly how thin, using strips of plastic to model the correctly scaled thickness of the atmosphere on a globe.

In this instructional task students are given two inequalities, one as a formula and one in words, and a set of possible solutions. They have to decide which of the given numbers actually solve the inequalities.

Math Snacks is a fun and interactive educational series. This website contains five animated videos focusing on key mathematical concepts included in the Common Core curriculum for grades 4-8. Each interactive is beautifully illustrated, contains audio, and is supported by supplementary printable resources. All learner resources are available in both English and Spanish. Teacher guides as well as teaching videos support classroom implementation. A powerful supplementary tool for educators teaching about ratios, rates, scale factor, unit conversion, and the number line, as well as a source for children's educational entertainment at home.
Math Snacks was developed by the Learning Games Lab located at New Mexico State University.

This course provides techniques of effective presentation of mathematical material. Each section of this course is associated with a regular mathematics subject, and uses the material of that subject as a basis for written and oral presentations. The section presented here is on chaotic dynamical systems.

Mathematically Productive Instructional Routines (MPIR) are short (10ish minutes), daily exercises aimed at building number sense. These six different MPIR are part of the Mathematically Productive Instructional Routines collection from the Washington Office of Public Instruction and the Washington Association of Educational Service Districts.

CK-12 Foundation's Middle School Math € Grade 6 Flexbook covers the fundamentals of fractions, decimals, and geometry. Also explored are units of measurement, graphing concepts, and strategies for utilizing the book's content in practical situations.

A work in progress, CK-12's Math 7 explores foundational math concepts that will prepare students for Algebra and more advanced subjects. Material includes decimals, fractions, exponents, integers, percents, inequalities, and some basic geometry.

Students will predict bond polarity using electron negativity values; indicate polarity with a polar arrow or partial charges; rank bonds in order of polarity; and predict molecular polarity using bond polarity and molecular shape.

Sixth grade students in San Diego, CA created a fictional book for young readers that explains mathematical concepts through an illustrated fantasy story. Inspired by the book The Number Devil, students created a narrative to transform the mathematics they were studying into compelling and clear concepts for readers. This film features an interview with the teacher, and investigates this question: If we want to students to persevere to solve problems, what will give them the motivation to persevere?

This short video and interactive assessment activity is designed to teach fourth graders about distance between items.

Students expand upon their understanding of simple machines with an introduction to compound machines. A compound machine a combination of two or more simple machines can affect work more than its individual components. Engineers who design compound machines aim to benefit society by lessening the amount of work that people exert for even common household tasks. This lesson encourages students to critically think about machine inventions and their role in our lives.

This 7th grade Nutrition Unit focuses on parts of the Michigan Model Curriculum. More specifically, students will learn information about the USDA My Plate guidelines, how to track calories, read food labels, make healthy choices, and much more.
