Add some randomization into simulations. The 11th installment in a series of 25 presents two new methods to use in simulations--colored disks, and random numbers. Pupils use random numbers to run simulations where the probabilities make...

Develop young mathematicians' ability to compare fractions with investigation into the number 1/2. After brainstorming a list of fractions equivalent to 1/2, children identify a pattern in the numerators and...

Through a variety of physical and theoretical situations, learners are led through the development of some of the deepest concepts in high school mathematics. Complex numbers, the fundamental theorem of algebra and rational exponents...

Capture the engagement of young mathematicians with this upper-elementary math instructional activity on measuring time and distance. Using Google Maps, students first measure and compare the distance and time it takes to travel...

Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

Have young mathematicians subtracting fractions in no time with this manipulative-based math activity. Using their sets of fraction circles, students explore a number of word problems involving the subtraction of fractions before working...

How do you operate with numbers in scientific notation? The resource provides examples on how to divide and multiply with numbers written in scientific notation. The handout and video also cover the procedure for addition and subtraction...

Animals and plants develop relationships and rely on each other to survive. Pupils learn more about symbiosis through a video, a hands-on matching activity, and a game. They differentiate and describe each type on a written evaluation.

Bring the excitement of genetics to scholars with a dynamic hands-on meiosis modeling experience. During the activity, biologists follow step-by-step procedures to build chromosomes, model independent assortment, learn about crossing...

How can we accurately estimate what the economy should produce now and in the future? Have your pupils tackle this question as they learn about real versus potential GDP and as they review data regarding the output gap in...

Pupils learn the steps for basic constructions using a straightedge, a compass, and a pencil. Pairs develop the skills to copy a segment and an angle, bisect a segment and an angle, and construct parallel and perpendicular lines.

Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...

Emerging statisticians develop the ability to make inferences from sample data while also working on proportional relationships in general. Here, young learners examine samples for bias, and then use random samples to make...

Show your future bakers how to choose the right baking pan by calculating the volume of a pan. The resource compares two pans, one with decimal edge lengths and is too small for the recipe and one that may work. Your number crunchers are...

Delve into the hard numbers and fundamental concept of income inequality in the United States, using graphs, detailed reading materials, and an organized worksheet.

Young scientists create monsters by applying their knowledge of transcription and translation. They randomly find the DNA, assign it a codon, and build monsters piece by piece. 

Estimate the value of one of the most famous irrational numbers. The hands-on instructional activity instructs classmates to measure the circumference and diameters of circles using yarn. The ratio of these quantities defines pi.

Clarify the Common Core standards for your eighth grade mathematicians with this series of classroom displays. By rewriting each standard as an achievable "I can" statement, these posters give students clear goals to work toward...

The process of elimination really works! Use elimination when substitution isn't doing the job. The 29th segment in a series of 33 introduces the elimination method to solving linear systems. Pupils work several exercises to grasp the...
