Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format instructional activity. 

Common Core is all about getting your learners to open their minds and think about the why and how. This problem has them thinking about unknown numbers and their relationship with one another when we round and...

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...

Who has the most? Young learners practice charting data using familiar information. They help fill out a classroom chart by recording the number of people, pets, televisions, etc. in their home. Guiding questions help them investigate...

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.

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

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

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.

Snow, ice, and water are all composed of H2O. Does that mean they all have the same volume? Discover the ways that the densities of these substances determine their volumes, and how they change based on their current states of...

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...

Using food as a manipulative is one of the best ways to incorporate hands-on learning in the classroom. This hands-on approach allows young mathematicians to compare, order, and identify fractions with the use of Twizzlers® and...

Cats can't add, but they do multiply! Determine the number of descendants of a single cat given specific facts about cats and kittens. The lesson focuses on developing strategies for problem solving using both individual and group work....

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.

The use of box scores from baseball games is the foundation of this math lesson. Organize your class into groups of four, and give identical box scores from a baseball game that was just played. Have them create word problems from the...

Is there a better way to display data to analyze it? Pupils represent data in a variety of ways using number lines, coordinate graphs, and tables. They determine that certain displays work with different types of data and use...

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...

Are the means the same or not? Groups create samples from a bag of numbers and calculate the sample means. Using the sample means as an estimate for the population mean, scholars try to determine whether the difference is real or not.

Learners apply their understanding of luck to a probability experiment. They play a game of Pass the Pigs to determine the probability of a specific outcome. Using analysis for their data, pupils declare the measures of center, dot...
