One of the hardest skills for many young geometers to grasp is to move beyond just declaring obvious things true, and really returning to fundamental principles for proof. This brief exercise stretches those proving muscles as the...

The Grapes of Wrath. The Jungle. Native Son. The Things They Carried. The Absolutely True Diary of a Part Time Indian. To address a current social, political, economic, or environmental issue, class groups pair the reading of a...

Begin your unit on William Shakespeare's The Tempest with a helpful anticipation guide. Learners read ten statements that connect to the play's literary themes, and note whether they believe the statement is true or false.

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...

Learners first complete an assessment task where they assess statements on probability. They then sort cards containing probability statements as being either true or false.

Identify the identity. Learners first solve equations to find the number of solutions. Scholars then determine if given equations are always, sometimes, or never true, leading to the concept of identities.

Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...

True or false — Double Stuf Oreos always contain twice as much cream as regular Oreos. Scholars first measure the masses of the filling in regular Oreos and Double Stuf Oreos to generate a class set of data. They use hypothesis testing...

Challenge the class to utilize their knowledge of linear and quadratic functions to determine the intersection of the parent quadratic graph and linear proportional graphs. Using the pattern for the solutions, individuals develop a...

Rutherford performed his famous experiment in 1907 with Marsden, showing the true atomic structure. This interactive simulation compares Rutherford's historical experiment to the Plum pudding model of the atom. In both models, alpha...

Inauguration Day is January 20. Implement an entire week's worth of mini activities to help young historians become knowledgeable of the President's job, the executive branch, and the White House. The worksheets focus on...

Read about the ways a beloved pet can help a girl meet her true love with a short fairy tale. As fifth graders read the passage, they note their inferences and answer four comprehension questions to demonstrate their understanding.

Knowledge of statistics and probability can increase your advantage when playing games. The activity asks learners to analyze the game of MasterMind to determine the number of possible codes. They also examine different variations of the...

Explore the consistency of the earth's layers and soil through modeling. By conducting an engaging experiment, learners develop a model for the earth's layers and a soil profile using edible materials. Each material is chosen based on...

Take learning outside and start classifying grasslands. Young ecologists observe grassland plants in order to classify them into the appropriate species by family. They note their characteristics and where they grow. A true...

Hit unlike fractions out of the park in a comparing fractions color by number (symbol) worksheet. Young mathematicians place <, >, or = to make each comparing sentence true. Then, they use a key to color accordingly. When complete,...

True friendship is priceless. Fourth graders read a short story about two friends who are willing to give up everything for each other — even their lives.

Connect science, math, and art for a true interdisciplinary lesson! Learners explore simple machines in art. Through analysis with a physics app, they identify positions of kinetic and potential energy and make conclusions about work.

What's the rule that makes it true?  A virtual function machine generates output values as learners submit the input values. Their job is to analyze the inputs and outputs for a pattern and write a function rule.

Does the value exist? The interactive allows pupils to visualize the Intermediate Value Theorem. Using the visualization, individuals respond to questions using specific values and general values. The class comes to the conclusion what...

Mislabeled bottles can cause a dangerous situation! Young chemists design a method for determining the true contents of a solution in a virtual lab activity. Their study of density helps them identify the makeup of the solution.

Who is more trustworthy when it comes to marijuana: a high school student, or The National Institute on Drug Abuse? Sources matter when reading informational text. Help teenagers discern which facts are true with an activity that focuses...

Cell size is limited by the surface area to volume ratio, but why is this true? Scholars measure the surface area and volume of cubes before placing them into liquid. After a set amount of time, they measure the uptake by diffusion for...

If it's on the Internet, it must be true ... right? Introduce young Internet explorers to the importance of fact-checking through a fun web-based activity. Pairs work together to read and analyze biographies about world explorers, then...
