Video: Comparing Decimals
Use this video to show older elementary mathematicians that they can compare numbers using the same thinking that they did when they were in the first grade. Sal compares decimal numbers using the greater than and less than symbols. He shows how he stacks numbers to compare each place value and determine which number is greater.

Compare Decimals Using a Number Line
Check out how a number line can be used to compare decimals to the thousandths place in the second of three videos. The instructor helps avoid the pitfall of thinking that a longer number equals a number of greater value. She then thoroughly walks through several samples, including a word problem, of comparing decimals on the number line.

Compare Decimals Using an Open Number Line
Learn a new tactic for comparing decimals: the open number line! This is the final video in a five-part series on reading and writing decimals to the thousandths. Beginning with a review of greater than, less than, and equal symbols, the lesson continues with a discussion of how many times greater each place is than the previous place, and how greater numbers are to the left, lesser to the right.

Comparing Decimals - mathmammoth.com
Part lesson, part worksheet, this handout walks math minors through the comparison of two decimal numbers. It teaches them the trick of tagging zeroes in to get the numbers to be the same length to better understand place value. A set of practice problems is provided so that pupils can practice comparing decimals using greater than and less than signs.

Fifth and sixth graders compare decimals to the place-value structure in the base-ten number system. They represent fractions as parts of unit wholes, as parts of a set, as locations on a number line, and as divisions of whole numbers. Pupils solve addition or subtraction word problems using fractions with like denominators.

Compare Decimals Using Base Ten Blocks
Use base ten blocks to gain a deeper understanding of how decimals stack up against each other. The fourth of five videos, it focuses on reading and writing decimals to the thousandths, using a thousand cube to represent one whole. Learners get to see two examples of comparing two numbers using the base ten blocks.

Compare Decimals Using Fractions
Fractions have many applications, and in this video, they are translated into an opportunity to compare the relative size of decimals in word problems. A review of greater than and less than symbols kicks off the instruction, followed by a discussion of the common misconception that a longer number is greater in value.

Study Jams! Compare Money Amounts
Elementary money makers are walked through five steps to compare two different amounts. RJ speaks slowly as animations display his explanations. He compares the price of a New York magnet to the amount of money his cousin has on hand to see if she can afford the souvenir.

Base Ten Activity
Base ten blocks are great tools for developing not only an understanding of whole numbers, but of decimals as well. This upper-elementary lesson uses these versatile manipulatives and the array model to teach young mathematicians how to multiply and divide decimals.

Math Lesson Plan: Comparing Decimals
How can a zero affect place value? After going over the definition of a decimal and reviewing how to convert to a fraction, the whole group works to compare numbers with decimals where the zeros are in different place values. Emphasis is placed on the fact that zeros work differently in decimals than they do in whole numbers.
5th - 6th Math
Comparing decimals can be easy. Watch and learn how to line up four decimal numbers vertically and then starting from the left, compare each number in each place value to determine which is largest and which is smallest. This procedure is clear and because it's not a complicated topic, explained very well.

Comparing and Ordering Decimals
Which decimal is greater? Learners start by comparing eight pairs of decimals, writing in the symbol (> or <) to indicate values. The next two sections involve sets of three decimals. They start by circling the decimal with the greatest value in each set and then order sets from greatest to least.

Represent Equal Decimals Using Zeroes
How can two decimals be written differently but still be equal? With zeroes! That's what learners work to understand in the third of five lessons on reading and writing decimals to the thousandths place. Visuals that help learners grasp the concept include dimes versus pennies and tens blocks versus ones blocks and hundreds blocks.

Finance: Depreciation (Double Declining)
Of particular interest to a group of business and finance pupils, this lesson explores depreciation of automobile values by comparing the double declining balance to the straight line method. Mostly this is done through a slide presentation and the working of sample problems together as a class.

Reading and Writing Decimals
Decimals are quite often confusing for young mathematicians. Pupils engage in three activities: writing decimal names, understanding place value, and comparing decimals to thousandths. At the end of the lesson, there is a motivating game called beat the clock which will test your students' ability to correctly write decimals.
