Jeans length is a hot topic for preteens, and in this lesson, Mia helps us figure out how to round the length of various pairs so that Zoe can get some as close to 32.45 inches as possible. She uses a number line or ruler to prove the...

Through four steps, three different time values for a 100-meter run are arranged on a number line in order to practice ordering decimal numbers. The price of two sports drinks are also compared. All of this comes in narrated and animated...

Which is bigger? The sixth installment in an 18-part series covering decimals provides a lesson on comparing decimals to the thousandths. Teachers use place value to help class members compare and order decimals. Instruction encourages...

Order up a resource on comparing rational numbers. Scholars order fractions, decimals, and percents by converting to a single form. They conduct a cut-and-paste activity ordering three sets of rational numbers.

Step 1: Use the resource. Step 2: Watch your class become experts in solving two-step problems. Scholars learn to solve two-step word problems in context. They use tape diagrams and algebraic techniques to break the problem into two,...

If percents, fractions, and decimals can all mean the same number how do we go from one to another? During this instructional activity, watch how it goes over the basic steps needed to go from one rational number to the next. Both...

Straight from the pages of a math textbook, this three-lesson series introduces young mathematicians to the world of integers. Starting with a definition of integers and their applications in the real world, this resource goes on to...

The ninth installment of a 21-part module has pupils compare integers and rational numbers in decimal and fraction form. They match stories to number lines and compare values in the stories.

Statements often have multiple interpretations — but not these inequality statements. Scholars compare rational numbers and write inequality statements symbolically. The lesson includes problems that require comparing three numbers.

Boiling down any division problem to a one-digit divisor problem sure makes estimation easy. The lesson plan shows how to estimate division problems by using place value understanding and basic arithmetic facts to simplify the division....

Many math concepts are covered through this resource: percentages, decimals, ratios, exponential functions, graphing, rounding, order of operations, estimation, and solving equations. Colorful worksheets and a link to a Google search for...

Conquer any irrational fears you might have of irrational numbers. As class members investigate how to represent numbers geometrically, they learn about rational and irrational numbers, including approximating and ordering rational...
