Help your kids develop strategies for counting. In this base-ten lesson, learners use matching cards, base 10 blocks, and dry erase markers and boards to examine the base 10 counting system.

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...

It's time to discover what your classes have learned! The final lesson in the 25-part module is an assessment that covers the Pythagorean Theorem. Application of the theorem includes distance between points, the volume of...

Measure your pupil's learning in a lesson plan designed to explore decimals by weighing different candies on a scale and recording the weight. Small groups then compare and order the decimal weights on a number line to show their...

Learners practice estimating by handling items in groups of ten. They visualize how much space 100 items, such as pennies, peas, or beans, will take up after holding 10 of them. Students measure the difference in volume between 10...

Here is an excellent lesson plan on the water cycle and the states in which water exists. Learners identify the features of the water cycle, describe how water changes form, and look at ways that people affect the natural movement of...

Why did the Articles of Confederation fail? Your historians will find out firsthand through this simulation activity, during which they will use money (consider using extra credit) to demonstrate the inherent flaws. It's simple: each...

Examine the various rigid transformations and recognize sequences of these transformations. The instructional activity asks learners to perform sequences of rotations, reflections, and translations. Individuals also describe a sequence...

Apply pupil understanding of exponent properties to prove the relationships. In the sixth instructional activity of the series, individuals are expected to prove relationships using mathematical statements and reasoning.

Be sure to look both ways when making a two-way table. In the lesson, scholars learn to create two-way tables to display bivariate data. They calculate relative frequencies to answer questions of interest in the 14th part of the series.

Scholars model the height of water in a container with an exponential function and apply average rates of change to this function. The main attraction of the lesson is the discovery of Euler's number. 

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Examine scenarios involving number patterns. Learners complete a series of activities, including working with Pascal's triangle ando completing chart activities based on different pricing for pizza toppings. An included extension has...

Demonstrate to your middle school science learners how chalk breaks down in a weak acid. Discuss what affects acidic rain might have on ecosystems. Lab groups then choose one of two questions: "How does acid precipitation affect an...

Second graders identify the three phases of matter and demonstrate how a property can change states of matter. In this states of matter instructional activity, 2nd graders make an Ooze to discover how a solid changes into a...

What a fantastic project idea for discussing not only the history of America's expansion into the West, but for reviewing any major unit of history in your class. Pupils build stamp collections to visually represent themes of the...

Covering 23% of the continent and holding 64,900 cubic kilometers of water, the Great Artesian Basin is the primary source of water for much of inland Australia. Using detailed student worksheets, experiments, and case studies,...

Your pupils may believe that you and their parents are the oldest things in the universe, but surprise! There are elements of the universe that are even older. Elementary scientists create a class timeline to demonstrate the...

An outstanding lesson awaits your physics fledglings! After reading about how hydrogen can act as an energy carrier, they examine the electrolysis of water using solar power. They test the gases produced for flammability and will...

Hands-on stations in which groups of primary learners experience what mirrors can do provide opportunities for experimenting and authentic discovery. Recording their observations in complete sentences seems age-inappropriate. Drawing...

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...

It's more than just numbers on a line, its an organizational, mental math machine to help learners understand the value of numbers. The tool is handy when introducing positive and negative integers to see their values and...

Students describe the purposes of the Treaty of Versailles. In groups, they analyze the causes and effects of the treaty and discuss why the Americans were so against it. They note ideas for and against its ratification and they make...

Practice basic operations for young mathematicians in fun ways! Using two decks of cards (Ace through 10 plus the joker), learners play "memory" by matching numbers that can be added to make 10 and writing number sentences. In another...
