Using patty paper, classes determine that only one triangle is possible when given two specific angle measures and a side length. As the 10th instructional activity in the series of 29, young math scholars add these criteria to those...

Area is the amount of space that takes up the inside of a figure. To find the area of a rectangle, one must multiply the length by the width. Here, third graders are challenged to find the missing side length, given the area.

In this online interactive literature worksheet, students respond to 11 short answer and essay questions about F. Scott Fitzgerald's This Side of Paradise. Students may check some of their answers online.

Just what does it take to show two rhombuses are similar? The assessment task asks pupils to develop an argument to show that given quadrilaterals are rhombuses. Class members also use their knowledge of similar triangles to show two...

Start the exploration of trigonometry off right! Pupils build on their understanding of similarity in this lesson that introduces the three trigonometric ratios. They first learn to identify opposite and adjacent...

Are we interested in crime stories because we either identify with the victims or enjoy watching the rich suffer? Do we feel guilty and want someone to take our blame and let us feel innocent? Groups investigate how the author of "How...

Encourage your young scholars to interact with the text as they read. While reading "Three Skeleton Key," class members note predictions, define words and study their meanings, take notes on how the suspense builds, and jot down...

Is losing cultural traditions the cost of social progress, or should people make stronger efforts to preserve these traditions? High schoolers watch a short film about the native Yup'ik people in Alaska and how they handle the shifts in...

What figure is formed by connecting the midpoints of the sides of a quadrilateral? The geometry assessment task has class members work through the process of determining the figure inscribed in a quadrilateral. Pupils use geometric...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Investigate the various properties of the number six with this elementary math lesson. From simple addition, subtraction, multiplication, and division problems to the creation of hexagonal tessellations, this lesson covers all aspects of...

Choosing sides is no easy matter, and this was certainly true for the citizens of Baltimore in the beginning stages of the Civil War. Using video, group analysis of several primary sources, and discussion, this detailed and thorough...

Learners take on the roles of jurors in a civil case to evaluate evidence and determine a verdict in this engaging online interactive experience.

What do you need to prove triangles are similar? Learners answer this question through a construction exploration. Once they establish the criteria, they use the congruence and proportionality properties of similar objects to find...

After a lesson like this one, your class won't hesitate to negotiate! Pupils pair up and negotiate opposing sides of a conflict during the ninth installment in a 15-part series. Once they determine their wants and needs, individuals...

Take a terminal side for a spin. Pupils use an interactive to investigate angles of rotation that share the same terminal side. Scholars create coterminal angles and calculate what other angle sizes share the same final position.

The beginning of the 20th century began with a shock: the assassination of President McKinley. The man who would take his place—the youngest American to ever become president—led quite a life before stepping foot in the Oval Office. An...

Every time you make a choice, it prevents another option from taking shape. Spend some time analyzing "The Road Not Taken" by Robert Frost with a reading activity that includes four discussion questions that recall evidence from the text.

Finding the sum of the measures of three angles is easy, unless you have no clue what the measures are. Learners use an interactive diagram to see a geometric problem in a different way. A set of challenge questions takes them through...

Expand trigonometric ratios beyond right triangles. Pupils start with a review of trigonometric ratios and then take a look at angles in standard position to determine their measurements. Scholars discover how to find coterminal angles...

Just as Bud, from the novel Bud, Not Buddy by Christopher Paul Curtis, had rules to live by, so does the poem, If by Rudyard Kipling, but how do the two relate? Pupils delve deep into the poem's third stanza, participate in a grand...

How can your draw three-dimensional figures on paper? The lesson shows pupils how to draw orthographic projections of three-dimensional figures composed of cubes. After viewing a PowerPoint presentation, they practice this skill with...

The magic number is six! Using a 6x table, young math stars practice adding, subtracting, multiplying, and dividing two-digit numbers with the number six. This activity also touches on making tessellations with hexagons. 

Take some notes on integers! Learners can use the number line and thermometer provided along the bottom and side of the page to help visualize and understand positive and negative numbers.
