Middle and high schoolers solve four word problems based on three different graphs of ordered pairs which show the amount of money spent on lunch on particular days. Next, learners are given two equations of functions, and an x value and...

To recall or not to recall, that is the question. Using provided data, pupils calculate the percent of people that may fall ill on average. The scholars determine the standard deviation based upon the mean and the empirical rule,...

Pupils learn how to control food spoilage by adjusting the food's pH. They see that one of the most dangerous bacteria can grow in food if people don't handle and store food properly. Using knowledge of the bacteria's preferred pH,...

Second graders find missing addends by solving math word problems. In this missing addend lesson, 2nd graders work in a whole group setting to find the missing addends in word problems before using the strategies to work independently....

Students work together to design a service learning activity for their community that would benefit the Tijuana estuary. Using the internet, they research the elements of a service learning project and plan their's accordingly. They...

Complete problems using base ten blocks to see the difference in the place value of a decimal and how it affects a number's value. Learners compare decimal values as well. Ample time for discussion and modeling are allowed in the...

Learners identify and define the rules of properties of real numbers. They rewrite each of the problems listed using the commutative or associative properties. Pupils apply problem solving strategies to clarify situations in a table...

Help young mathematicians build a solid understanding of division with this base ten block activity. With the help of these popular math manipulatives, children model different math problems in order to reinforce the...

Students investigate the protein cytochrome c in an attempt to use its genetic chemistry to study possible evolutionary relationships between organisms. The instructional activity integrates technology with the use computers to perform...

Young mathematicians listen to the book Sold!: A Mathematics Adventure by Nathan Zimelman where they encounter ways to solve story problems. They then create and solve start unknown addition and subtraction equations. Resource builds in...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Some scientists argue that air pollution now causes more deaths than smoking. The second unit in a six-part series focuses on air quality. Scholars learn what's in the air, how clean the air around their school is, and what they can do...

The final lesson in the 21-part series on climate change focuses on energy solutions to the consumption problem. Using data specific to their school, pupils make recommendations, follow up on actions, and carefully track progress....

Life changes may cause stress. Here, scholars identify stressful situations in a peer's life and offer coping skills to make for a better day. A short story, "Stressed Out Sally," provides pupils with a look inside a bad day. After...

 A whole-class discussion sheds light on school bullying and ways to prevent it. Scholars share a moment when they observed or experienced some sort of teasing. Pupils brainstorm ways such behavior can be stopped or prevented.

Introducing exponential equations means learners need to take all the rules and tricks they learned for exponents and actually apply them. This presentation comes to the rescue by touching on changing bases in exponential...

How do people manage to get everything done when there are so few hours in a day? Scholars explore the question as they participate in small group discussions about time management. They construct a daily schedule and complete a...

Using a Venn diagram, pupils compare the similarities and differences between two classmates. Next, they review the CARE acronym (Collaboration, Acceptance, Respect, Empathy) and discuss how it applies to diversity in the classroom.

As an exercise in self-awareness and improvement, class members create a Conflict Shield listing 12 skills they believe are the most useful in conflict resolution. They then color the ones they have mastered while leaving uncolored those...

High schoolers determine the surface area of the Luxor Hotel, using the square feet of the base, volume, and the volume formula. They create a scale model of the triangular/pyramid shaped hotel.

Explore scientific notation in this mathematics lesson. Young mathematicians explore multiple representations of large number in scientific notation through the use of models, visual representation and expanded form. The lesson provided...

Developing and maintaining healthy interpersonal relationships is difficult, especially as middle schoolers begin dating. A short activity permits eighth graders to practice their skills as they consider how they should respond to a...

You've heard that it is true, but can you prove it? Scholars learn the Pythagorean Theorem through proof. After an overview of proofs of the theorem, learners apply it to prove triangles are right and to problem solve. This is the second...

How can mathematics help scholars choose a college? High schoolers learn how they can use decision matrices to rank colleges based on selected criteria. They also see how to weigh criteria using multiplication of the decision matrix by a...
