Building on knowledge from the previous lesson, the second lesson in this unit teaches scholars to identify and interpret rate of change and initial value of a linear function in context. They investigate how slope expresses the...

What makes a good best-fit line? In the 10th part of a 16-part module, scholars learn how to analyze trend lines to choose the best fit, and to write equations for best-fit lines to make predictions.

This lesson introduces the idea of slope and defines it as a numerical measurement of the steepness of a line. Pupils then use the definition to compare lines, find positive and negative slopes, and notice their definition holds for...

Use the distributive property to solve equations. The sixth lesson plan in a 33-part series has scholars solve equations that need to be transformed into simpler equations first. Class members apply the distributive property to the...

Five problems provide practice for learners to find the area of a circle given the distance of the radius. Answers on the key use pi as a variable and do not include fully computed numeric answers. To reinforce basic multiplication facts...

Discover how to calculate the expected value of a random variable. In the seventh installment of a 21-part module, young mathematicians develop the formula for expected value. They connect this concept the dot product of vectors.

Challenge the class to determine the equation of a line. The 21st part in a 33-part series begins with a proof that every line is a graph of a linear equation. Pupils use that information to find the slope-intercept form of the...

Prove the Angle Sum Theorem of a triangle using parallel line and transversal angle relationships. Pupils create a triangle from parallel lines and transversals. They find angle measures to show that the angles of a triangle must total...

Determine the slope when the unit rate is difficult to see. The 17th part of a 33-part series presents a situation that calls for a method to calculate the slope for any two points. It provides examples when the slope is hard to...

Everyone does their fair share. The sixth segment in a 22-part unit presents the mean as a fair share. Groups build a conceptual understanding of the mean of a data set, rather than simply learn an algorithm. Learners use the...

Tap into your pupils' imagination by asking them to design futuristic, ideal cities. They must discuss and take scale and size into account, looking at some model pieces of art for inspiration and analysis. The final product for each...

Viruses can spread like wildfire, and mathematics can model the speed of infection. Given a function, scholars analyze it to describe the spread of a disease within a stadium. Learners find the initial number infected and the maximum...

Sixth graders visualize different percentages as parts of a whole on visual images. They observe alterations of photographs, and models of circles, squares and sets. This incredibly detailed, eight-page plan leads you through everything...

Learners understand why historians conduct research and the importance of perception when it comes to studying history. The resource covers The Wars of Expansion and the Battle of Little Bighorn/Greasy Grass through group work, debate,...

Extend the place value system. The first lesson plan in a series of 18 extends the place value system to millions through thousandths. Using place value charts, pupils see how the value of a digit changes as it moves places. Teachers use...

Everyone loves pizza! Learners define fractions and use manipulatives to calculate fractions. Kids cut circles to represent various fractional parts of a pizza. Some accommodations are included. 

Extra! Extra! High schoolers read about Dolores Huerta, the social activist who helped organize the United Farm Workers. Researchers read primary and secondary sources about Huerta's work and craft a headline, supported by three pieces...

Middle school years can be tough. An educator's guide for the works of Lynda Mullaly Hunt introduces readers to two texts that discuss the struggles pre-teens face during middle school. Chapter-by-chapter questions and activities for two...

Young historians climb through the three branches of the US government in the third lesson of this five-part series. While reading the first three Articles of the Constitution in small groups, children write facts on paper leaves...

The Bill of Rights is much more than an important piece of paper! The rights cover everything from freedom of speech to the right to remain silent if arrested. Scholars find out their own rights by answering the questions in the form of...

Log the values of the derivative of a logarithm. The interactive plots the derivative of the natural logarithm. Learners first determine the derivative of natural logarithm and the general logarithm. Using the formulas for the...

Discover the cultural practices and unique value systems of a group of native peoples from Canada called the Kwakwaka'wakw. Your young historians will discuss how conceptions of wealth can vary and how these native...

Just because kids today are well-versed in texting and emails doesn't mean they shouldn't learn how to write a friendly letter! Reinforce their letter-writing skills with a lesson focused on the elements of a friendly letter, as...

Explore the properties of parabolas in this lesson plan. Construct a parabola given a focus and a directrix on the Ti-Nspire. Write equations of parabolas in vertex form and determine the a value of a parabola given a focus and directrix.
