What are Natural and 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...

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...

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

Follow along as the instructor demonstrates how to subtract a whole number from a fraction. First, she changes the whole number to a fraction. Then she finds the least common denominator of the two fractions. Finally, she does the...

Practice adding whole numbers by combining the amount of fish Alice and Bob catch. As young mathematicians work through each problem, they are asked to find one more plus the amount of fish already caught. They can manipulate the...

As penguins jump off of an iceberg, young mathematicians count the remaining penguins in order to discover the whole number subtraction answer. As they work through the questions, they can manipulate the red dot to add and subtract more...

Estimating is an essential skill used in everyday life. This presentation explains how to apply prior knowledge about rounding numbers to estimating sums and differences. Example problems and assessment include large numbers, making this...

The instructor illustrates place value by first drawing a place value chart. Then she inserts the numbers in question so she can find the value of certain digits. I think her chart really helps visually.
