Young mathematicians construct their own understanding of integers with an inquiry-based math lesson. Using colored chips to represent positive and negative numbers, children model a series of addition and subtraction problems as...

An inquiry-based algebra lesson plan explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as well as the...

Before diving into operations with fractions, learners discover the foundation of fractions and how they interact with one another. Exactly as the title says, logic of fractions is the main goal of a resource that shows pupils how...

Young mathematicians dive into the number line to discover decimals and how the numbers infinitely get smaller in between. They click the zoom button a few times and learn that the number line doesn't just stop at integers. Includes...

Weight is a function of the distance from sea level. Learners explore the many implications of this fact in an inquiry-based task. Given the function, pupils answer questions before manipulating the function to rewrite the distance...

Keep your pets slim, trim, and healthy using mathematics! Pupils use a linear programming model to optimize the amount and type of food to provide to a pet rabbit. They model constraints by graphing inequalities and use them to analyze a...

When is finding the discriminant enough? Using the quadratic formula helps find solutions to quadratic equations, but there are times when just using the discriminant is appropriate. Use this algebra II instructional activity to...

Teach solving absolute value inequalities through inquiry. Groups use their knowledge of absolute value and solving inequalities to find a solution set to an absolute value inequality. Working collaboratively encourages discussion,...

What is your credit score? How do you find it? Help your pupils answer these questions and more. They will access their free credit report and then analyze its meaning.

Some items keep their shape no matter what happens! Have your kindergarten class choose which items would stay the same if they were bent, stretched, or squashed. The last activity prompts kids to see what happens when they stretch a...

How does sound travel in a string walkie-talkie? Third graders read about the way vibrations act between two cups and a string. Next, they put the steps in order, and experiment with their own walkie-talkies.

Growing is part of being a living thing. Kindergartners decide which illustrations represent the life cycle of a living thing, then put a check mark next to the correct pictures. They then examine their own growth on a height chart.

Learn how to measure weight with newtons in a science experiment about gravity. After they read a short paragraph about force, fifth graders draw an arrow to indicate which way a spring is being pulled. Next, they survey their family...

Fifth graders read an informative paragraph about how blood travels through our bodies. Then, they fill in the missing letters for words that label things in the circulatory system. An answer key is provided on page two. An interesting,...
