Pupils determine scale factors from one figure to another and the scale factor in the reverse direction. Scholars compute the percent changes between three figures. 

Determine the difference between a sample statistic and a population characteristic. Pupils learn about populations and samples in the 14th portion in a unit of 25. Individuals calculate information directly from populations called...

Classmates apply midpoint concepts by leapfrogging around the complex plane. The 12th lesson in a 32 segment unit, asks pupils to apply distances and midpoints in relationship to two complex numbers. The class develops a formula to find...

Changing ratios make for interesting problems. Pupils solve problems that involve ratios between two quantities that change. Groups use tape diagrams to represent and solve classroom exercises and share their solutions. 

What linear equation will fit this data, and how close is it? Through discussion and partner work, young mathematicians learn the procedure to determine a regression line in order to make predictions from the data. 

Forgive me, I regress. Building upon previous modeling activities, the class examines models using the regression function on a graphing calculator. They use the modeling process to interpret the context and to make predictions...

Here's an activity that uses a reading comprehension strategy based on Bloom's taxonomy to focus readers' attention on key passages from Edward Bloor's Tangerine. Worthy of a place in your curriculum library.

Satellites require rockets to launch, but it doesn't take a rocket scientist to understand them. Future engineers learn about how satellites send data to Earth and how to interpret satellite images. They see how radio waves play a role...

High schoolers study about deriving centripetal acceleration for motion at constant speed around a circle.

Students identify functions and proper use of the computer. They identify secondary colors by mixing primary colors. Students reinforce listening, speaking and following directions by playing a game. They identify the color gold.

As learners build the "girders" of conversation by staying consistent on a particular topic, they avoid the "wrecking ball" of an off-topic comment. To help students develop this important conversation skill, this resource provides...

Learners practice remaining on topic during a conversation using printouts of chains as visual models for their work. Chains are placed in sequence while students stay on a shared topic of conversation, and a broken chain is used as...

Passages from Unbroken and Farewell to Manzanar provide the context for a study of the historical themes of experiencing war, resilience during war, and understanding the lasting trauma of war. Appendices include extension...

Examine human resilience across two texts with a detailed unit. Over the course of a week, learners will conduct a close reading of excerpts from Unbroken and Farewell to Manzanar. The resource includes clear procedures for reading and...

Do ratios have values? The seventh lesson in a series of 29 introduces the value of a ratio. Pupils create associated ratios to a given ratio. They also describe the fraction associated to the ratio as the value of the ratio.

Show your math class how to use vectors in adding complex numbers. Vectors represent complex numbers as opposed to points in the coordinate plane. The class uses the geometric representation to add and subtract complex numbers and...

The second day of a two-part lesson on motion introduces the class to circular motion. Pupils learn how to incorporate a time parameter into the rotational matrix transformations they already know. The 24th installment in the 32-part...

Measure the temperature of your math class with a temperature-based lesson on adding and subtracting rational numbers. The thermometer serves as a vertical number line for learners as they work together to solve a temperature change...

Review the principles of scaling areas and draws a comparison to scaling volumes with a third dimensional measurement. The exercises continue with what happens to the volume if the dimensions are not multiplied by the same...

Triangles, triangles, and more triangles! In this second installment of a 36-part series, your young mathematicians explore two increasingly challenging constructions, requiring them to develop a way to construct three triangles that...

Kids practice using five types of context clues (definition, synonym, antonym, example, and general) to decode idiomatic language.

Through a variety of hands-on activities and physical scenarios, this far-reaching unit leads learners through an exceptionally thorough exploration of circles and parabolas as conic sections. Geometric construction techniques are used...

You never know what you will find next in the deep sea ecosystem. So far, scientists have found items that work as anti-tumor agents, anti-inflammatory agents, agents that stop uncontrolled cell division, and much more. The lesson begins...

A geometry module connects algebraic reasoning to geometry. It challenges scholars to investigate the slope criteria for parallel and perpendicular lines, prove theorems involving coordinate geometry, and write equations for circles and...
