A letter addressed to President Roosevelt and another addressed to Eleanor Roosevelt offer insight not only into these two amazing historical figures, but also into the struggles people faced during the Great Depression. 

Lesson 7 focuses on building academic vocabulary and writing an explanatory letter with supported textual evidence. For the first five minutes of the lesson, the educator reminds the class of how to read and refer to the accordion...

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...

It doesn't matter whether secant lines intersect inside or outside the circle, right? Scholars extend concepts from the previous lesson to investigate angles created by secant lines that intersect at a point exterior to the circle....

Find out just how smart your young mathematicians are with this cross-curricular math and language arts lesson. After first reading Shel Silverstein's poem "Smart", students draw pictures of coins to model the different exchanges...

Build right angles using coordinate geometry! Pupils explore the concept of slope related to perpendicular lines by examining 90-degree rotations of right triangles. Learners determine the slope of the hypotenuse becomes the opposite...

Describing a line using an algebraic equation is an essential skill in mathematics. The previous instructional activity in the series challenged learners to determine if segments are perpendicular with a formula. Now they use the...

Math class is full of drama—there are so many problems to work out! Pupils work out factoring problems. They use quadratic methods of factoring higher degree polynomials, in addition to factoring the sum and difference of two...

Define parallel lines through transformations. The third lesson of 18 examines the result of the translation of a line. Two possible outcomes include coinciding lines and parallel lines.

Time for pupils to use their imagination! Learners examine the relationship between a system with no real solution and its graph. They then verify their discoveries with algebra. 

Quadratic solutions come in all shapes and sizes, so help your classes find the right one! Learners use the quadratic formula to find solutions for quadratic equations. Solutions vary from one, two, and complex. 

Discover the relationship between tangent lines and the tangent function. Class members develop the idea of the tangent function using the unit circle. They create tables of values and explore the domain, range, and end behavior of...

How can matrices help us solve linear systems? Learners explore this question as they apply their understanding of transformation matrices to linear systems. They discover the inverse matrix and use it to solve the matrix equation...

Explore the patterns of fractions that produce finite and infinite decimals. The sixth lesson of the series asks learners to determine a similar feature of fractions that produce finite decimals. Using the patterns, pupils create...

Proficient reading of informational text, especially primary source documents, requires practice. This message from Thomas Jefferson about the Louisiana Purchase offers readers a chance to develop these comprehension skills.

If you build it they can come. After reading a short article about the impact of western expansion, middle schoolers cite evidence from the article to explain how this expansion forced changes in transportation.

Lead your class toward mastery of making inferences with a straightforward worksheet. Pupils read four short passages and make inferences based on the questions asked about each passage. They explain their reasoning for each...

Use everything you know about quadratic equations to solve polynomial equations! Learners apply the Zero Product Property to factor and solve polynomial equations. They make a direct connection to methods they have used with quadratic...

Five out of four people have trouble with fractions! After comparing simplifying fractions to simplifying rational expressions, pupils use the same principles to multiply and divide rational expressions. 

What do fractions and rational expressions have in common? Everything! Learners use common denominators to solve rational equations. Problems advance from simple to more complex, allowing pupils to fully understand the material before...

Examine numbers in scientific notation as a comparison of size. The 14th lesson in the series asks learners to rewrite numbers as the same power of 10 in scientific notation to make comparisons. Pupils also learn how to use a calculator...

Investigate nonlinear motion through an analysis using the Pythagorean Theorem. Pupils combine their algebraic and geometric skills in the 24th lesson of this 25-part module. Using the Pythagorean Theorem, scholars collect data on the...

Prepare to teach Jan Brett stories by taking a look at this teacher resource, which includes text-based questions, writing assignments, discussion ideas, and vocabulary practice for 18 different stories.

Pairs of contradictory words introduce learners to paradoxes, the literary device writers use to get readers thinking deeply about their messages. An interactive lesson uses poems by Emily Dickinson and Wilfred Owen and excerpts from the...
