Fraction ÷ Whole Number (I)

Visual models support young mathematicians as they deepen their fractional number sense in this elementary math instructional activity. Using fraction circle manipulatives, children explore basic unit fractions as they develop the...

Working in groups, the class will use what they know about whole number operations to solve a real-world problem involving a number line. They will focus on using the number line to correctly label the placement of whole numbers,...

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...

Expand on prior knowledge of place value to teach your class how to round whole numbers. This essential skill is explained with the help of a number line before introducing the explicit rules for rounding numbers up and down. Work...

A demonstration of how to multiply a whole number times a fraction.

Two very similar numbers and you have to figure out which one is larger. The teacher diagrams a place value chart and shows you how to write the two numbers to make a comparison.

Whole numbers are the natural numbers including zero. The instructor illustrates and explains place value. She draws a place value chart and then defines each term and what the numbers mean. She writes a number in standard form and then...
