You know 4 + 4 + 4 = 3(4), but what about x + x + x? Pairs work together to develop equivalent expressions relating multiplication and addition in the third lesson of a 36-part series. They extend their knowledge of multiplication as...

Do you want to use the resource? Absolutely. Scholars learn about absolute value and its relation to magnitude and distance on a number line. They compare numbers in context by applying absolute value. 

It's all about lines when going around. Pupils graph the relationship between the length of a side of a square and its perimeter. Class members explain the origin in context of the side length and perimeter. They compare the graph to the...

One is chance, two is a coincidence, three's a pattern. Scholars must determine similarities and differences of a regular hexagon undergoing dilation. They look at lengths, angles, areas, and symmetry.

Continuing from the previous lesson in the series, scholars learn to use positive and negative integers to describe real-world situations. In groups, they come up with their own situations for given positive and negative integers. 

How can you compare linear functions? The seventh installment of a 12-part module teaches learners how to compare linear functions whose representations are given in different ways. They use real-world functions and interpret features in...

Explore angle relationships associated with transversals. Pupils construct parallel lines with a transversal and find the measures of the angles formed. They figure out how the different angles are related before constructing...

This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...

How fast is your class? Learners determine the amount of time it takes individuals to walk a given distance and calculate their speeds. Pupils solve distance, rate, and time problems using the formula and pay attention to the...

Use a unit approach in developing a fraction division strategy. The teacher leads a discussion on division containing units, resulting in a connection between the units and like denominators. Pupils develop a rule in dividing fractions...

You don't want to flush your money down the drain! Have your classes complete a financial comparison between two different types of toilets. They use linear modeling to determine the most cost-effective model.

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...

Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson plan, students calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes....

Estimating the value of numbers is much harder than it sounds! Scholars compare and order the value of numbers presented in different forms including fractions, decimals, roots, integers, and pi. This builds on the previous lessons in...

Explore line graphs and their characteristics through an interactive lesson. Scholars follow a set of directions to plot data on a line graph. They then answer questions about the type of variables, minimum and maximum values, and...

  Students solve algebraic equations. For this algebra lesson, students investigate linear and inverse operation of equations. Students practice solving for x and plugging in values into an equation.    

Should refugees fleeing poverty be allowed the same entrance into the United States as those fleeing persecution? High schoolers read about US foreign policy in the late 20th century regarding refugees from Cuba and Haiti, and engage in...

Which shape is the same? Young geometers match a triangle, circle, rectangle, and square to their identical counterparts, connecting them with a line from left to right. Then, they do the same thing with a set of four circular shapes,...

These abstract shapes are pointing in different directions and young scholars determine which ones are oriented the same way. For each of five starting shapes they examine a set of four identical figures pointing in various directions,...

Which of these shapes is pointing the same way? Pre-readers examine five rows of familiar objects. The first item points to the right for each, and they must determine which of the subsequent items in each row points the same direction....

Which shape is pointing the same way? There are five starting shapes here, all irregular. Learners examine a row of shapes following each and draw a circle around the one that is pointing the same way. Enforce directional vocabulary by...

Which of these shapes is congruent? Young geometers examine five familiar shapes: triangle, oval, rectangle, triangle, and circle. Each is followed by a set of shapes, of which one is congruent. They circle the congruent...

Even if your kids aren't reading yet, they can become familiar with words by identifying two that are the same. Youngsters focus on the word same as they examine eight words and match them to their identical spellings....

Groups write and evaluate expressions for various phone plans and scenarios to find which is the best deal. They then compare different approaches to writing expressions for the same scenario and discuss the concept of equivalent...
