The Long and Short of It

Third graders construct numbers to the millions place. In this 30-page place value lesson, learners create numbers and evaluate the place value of digits. They explore standard and expanded form of numbers. An incredible resource!

Third and fourth graders work with a coach to round whole numbers to the nearest 100, 1000, and 10,0000. They follow a step-by-step process and notes are provided for the coach.

In this math PowerPoint, the process of multiplying whole numbers and fractions is broken down into clear, sequential steps. Examples of each step are given numerically and in simple, easy-to-understand text. Story problems and examples...

This is the second in a series of 3 Khan Academy videos on rounding whole numbers. Students watch Sal Khan round the number 423,275 to the nearest thousand by looking to the number in the hundreds place. If it is 5 or higher, you round...

Rounding is an important skill which must be used throughout the study of mathematics. This Khan Academy video is the first in a series of 3. It shows how to round the number 24,259 to the nearest hundred, using a number line.

Adding double-digit numbers can seem difficult for some students. But, this Khan Academy video makes this process clear in a developmentally sound way. Students watch as 'Sal' adds the number 46 to 43. He references each number by its...
