Make your own number line ... using a compass. The first installment of a 21-part series has scholars investigate positive and negative integers on a number line by using a compass to construct points that are the same distance from zero...

Local linearity isn't the first thing that comes to mind to start off an AP® Calculus course. A scholarly article discusses one possible beginning to the AP® Calculus course: investigating and introducing derivatives through activities...

Is 0.56 stronger than -0.78? Interpret the correlation coefficient as the strength and direction of a linear relationship between two variables. An algebra lesson introduces the correlation coefficient by estimating and then...

How do you find the lengths of items that cannot be directly measured? The 13th installment in a series of 16 has pupils use the similarity content learned in an earlier resource to solve real-world problems. Class members determine...

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...

LEGO see if you can recreate my design. Individuals build an arrangement from LEGO blocks and write directions for someone else to follow in order to recreate the arrangement. Pairs then swap directions and try to...

Teach your class about the Declaration of Independence while giving them practice working as a team. The resource breaks participants into groups and has them answer questions about specific grievances from the Declaration of...

The lesson begins with direct instruction: how and when do we use avoir and être to form the past tense? After identifying the verbs that use either avoir or être, French learners write about five things they did the week prior. Then, in...

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...

Challenge the young mathematicians to find the exact coordinates of a dilated point. The fifth segment in a 16-part series introduces the class to the converse of the Fundamental Theorem of Similarity. Scholars use the theorem to...

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...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

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...

Do ratios have values? The seventh lesson plan 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 instructional activity 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...

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...
