Do You Need Lesson Plans and Resources to Teach Fourth Grade Math How to Round Numbers?

Last week we talked about learning how to write numbers in standard form, word form and expanded form is not only a standard, CC.4.NBT.2, but also a needed real world skill. Click here to read that previous post. This week's post is about how to round numbers. The standard is CC.4.NBT.3, generalize place value understanding for multi-digit whole numbers.

When teaching how to round LARGER numbers, it is best to review on the board or digit camera with some practice of rounding two-digit numbers. A perfect introduction is to put four or five students at the board and give them all a similar number, 83, 93, 33, 38, 98, 88, etc. Next, rotate your students up to the board with some three-digit numbers, but continue to only round to the tens. For example, round these numbers to the nearest ten, 359, 218, 394, 872, etc. If you get the answers 360, 210, 390 and 870, your students have a great handle on this skill and they are ready to move on to rounding much larger numbers. 

The students that give you 400, 200, 400, 900, etc. are looking at the "number next to it and then applying 5 and up rounds up, 4 and smaller round down." But they are not understanding what column to look at for their clue, therefore, missing the SKILL, applying only the trick.

By doing this four or five times with different groups of students, you will be able to see who has a real understanding of round numbers and who just knows the "rounding tricks." Your students that need help would be perfect to pull for your remediation, RTI, review, whatever you call your lowest math group, they need a better understanding of place value.

If you need an easier review for rounding numbers, I have a third grade math post with lessons and resources and freebies for rounding to the nearest 10 or nearest 100. Click here to read and review those lessons.

Once you feel that everyone has had a great review and are ready to continue with today's skill, rounding LARGER numbers, let your students have white boards and a marker or a clip board with paper. Teach them a 'quick draw' which is a skill for their mental tool box. Quickly draw an open number line and then put the number they are rounding in the middle. Use 339,404 for example. Then have the students write 300,000 and 400,000 at each end. Have them think, Is 339,404 closer to the 300,000 or the 400,000? They can even erase and write, and erase and re-write the number as many times as they need to move it closer to 300,000 or 400,000. 

Review many different examples and if needed, remediate your low group with some place value blocks and then guide them away for the hands-on method to the open number line method. 

I have a Bundle for Round Numbers that includes a center game and task cards.

FUN TIP:
Print the center game once, then on your school copier make a set for each student. That way you save on your ink. Let each student have one set and one baggie. They can make the center during math rotations and then take it home to review the skill with or without a family member.

Center Game Include:
* One Page of Problems
* One Answer Mats
* Adorable Center Cover
