Use the power of mathematics to find the number of red chips in a bag — it's a little like magic! The activity asks learners to collect data to determine the percentage of red chips in a bag. They calculate the margin of error and...

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

Don't leave your classes vulnerable in their calculations! Help them understand the importance of calculating a margin of error to represent the variability in their sample mean. 

Error does not mean something went wrong! Learners complete a problem from beginning to end using concepts developed throughout the last five lessons. They begin with a set of data, determine a population proportion, analyze their result...

Full of info, this handout provides the rules, properties, and common mistakes found in an algebra course. This cheat sheet is a great resource for those hard-to-remember exponent rules and hyperbola equations, along with everything else...

Read. Stop. Think. Scholars use a reading strategy to process the challenging text, "The Vietnam Wars." They read a paragraph and then stop to think about the text and its meaning. Readers then go on to work with partners and make notes...

With minimal setup and maximum freedom, young geometers are encouraged to think outside the box on a seemingly simple application problem. Though the task seems simple, measuring a given paper clip and finding how many 10 meters can...

Code red! Learners read an informational article about the Red Cross, discussing the gist of the text in small groups. On a three-column note catcher, pupils take notes to show how the Red Cross functions as a multinational aid...

Scholars learn about primary sources with a Primary Sources: Japanese-American Internment during World War II packet. Pupils work with a partner to read challenging sources in the packet while making notes in the margins. They then...

Infuse your unit on fractions, decimals, and operations with a thorough module about rational numbers. With a teaching guide, learner examples, templates for instruction, and lesson rationale, the module is a solid way to...

This quick set of problems provides a brief refresher on the arithmetic of complex numbers. Learners need to multiply, add and subtract, and remember features of i when raised to a power. Included solutions are clear enough that...

Statistics can be manipulated to say what you want them to say. Teach your classes to be wise consumers and sort through the bias in those reports. Young statisticians study different statistical reports and analyze them for...

Sometimes it's hard to relate to a new text. Teach kids to use their prior knowledge when reading something new with a comprehension exercise. A short passage tells them how to think of their brains like filing systems, and provides five...

Get to know your scholars with this in-depth survey that asks learners to rate, answer true or false, write short answers, and draw abstract visuals about their academic and personal preferences.

This lesson focuses on Annotation, a "writing-to-learn" strategy. It consists of writing explanatory notes and critical (analytical) commentary to yourself. Annotating text consists of two steps: (1) underlining, highlighting, circling,...

This lesson focuses on annotating or marking text to enhance understanding. It offers tools and techniques for marking text including adding marginal notes to annotated pages.

Good readers underscore or circle important information, write summaries and definitions in the margins, and note questions or disagreements to help them understand and participate in their own reading. This lesson will help you learn...

This lesson focuses on annotation including the tools and techniques for marking texts, annotating for meaning in a story, and adding marginal notations to your marked text.

This lesson focuses on annotating text to aid in understanding of the text including annotating an argument and poetry. It also provides tools and techniques for marking text.
