Grade 5 Math: Comparing Whole Numbers : Math Made Easy - By Lumos Learning
| 00:04 | Hi , I'm Rachel . And today we're going to | |
| 00:07 | be going over grade five math , comparing whole numbers | |
| 00:11 | . Whole numbers are numbers from zero and anything above | |
| 00:17 | zero . We're not going to be looking at negative | |
| 00:18 | numbers when we're dealing with whole numbers , because that's | |
| 00:20 | what we call integers . So it's natural numbers . | |
| 00:23 | 1234 on to infinity . And we also include the | |
| 00:27 | zero . Now , when we're comparing these numbers , | |
| 00:30 | we're gonna use a few different symbols we're gonna use | |
| 00:33 | greater than less than and equal to when you're teaching | |
| 00:38 | the fifth graders , right . Greater than or less | |
| 00:41 | than something that I like to remember is the bigger | |
| 00:44 | number , right ? Gets the bigger area on this | |
| 00:49 | , you know , sign , whereas the smaller number | |
| 00:52 | gets the small point . So if you're comparing , | |
| 00:55 | let's say five and two five is the bigger number | |
| 00:59 | five gets the bigger , um area and two is | |
| 01:03 | a smaller number . Gets that small point right there | |
| 01:05 | . And if you're gonna write it like this , | |
| 01:07 | you have to reverse it , too , is less | |
| 01:10 | than five and have them practice reading it out loud | |
| 01:13 | . So they get used to saying five is greater | |
| 01:15 | than two . Two is less than five , so | |
| 01:18 | they get used to these symbols . You can also | |
| 01:21 | have them learn greater than or equal to less than | |
| 01:25 | or equal to when they add that line below . | |
| 01:29 | The less than sign right becomes less than or equal | |
| 01:32 | to , so you can have two is less than | |
| 01:35 | or equal to five . You can also have five | |
| 01:39 | is less than or equal to five , right , | |
| 01:42 | because it's or equal to . And then , of | |
| 01:44 | course , with the equal to we know that five | |
| 01:46 | is equal to five . You can also even have | |
| 01:48 | them do something like five is not equal to six | |
| 01:53 | , right ? That doesn't work . So those are | |
| 01:55 | all symbols that you can have them familiarize themselves with | |
| 01:58 | . I'm Rachel and thanks for living with us today | |
| 00:0-1 | . |
