Number and Number Relations: Lesson 3

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.

The natural numbers begin at 1, 2,3 ... and go to infinity. The whole numbers begin at 0, 1, 2,3 É and go to infinity. So the only difference between natural numbers and whole numbers is zero.

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...

Time to crunch the numbers! Young scholars use an interactive number cruncher to practice operations with whole numbers. They input a number and watch as the number cruncher produces the output and then use the data pairs to determine a...

In this math worksheet, students complete 11 problems where they divide a number with decimals by a whole number. Examples are given in this well-designed worksheet.

You are given a number that is written out in words and now you have to write it in numerical form, and you have to write it in expanded form. The teacher helps you identify the period values and the place values to write the words in...

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.

So you want to put some given values in order from greatest to least? The instructor starts out by drawing a place value chart. She then inserts all the numbers into the chart. This helps you visually see their value so you can compare...
