This PowerPoint is to be used when teaching rounding. Specifically, it covers 4th grade Common Core State Standard 4.NBT.3. An included worksheet also reviews place value and how to write a number (expanded form, word form, standard form) reviewing Common Core State Standard 4.NBT.2.
This presentation is 17 slides long with a lot of animation. When teaching rounding, I present it in a little of a different way. Therefore, be prepared for this to be a little different than you're used to teaching it. Actually a 4th grader in my class a few years ago came up with this way and I thought it was so smart!
For example: Round 5,284 to the nearest 10.
I would say: Underline the number in the tens place. Now underline everything before that number also. Now you've underlined the number 528. This number is either going to stay 528 or round up to 529. Circle the number to the right of the tens place. This is the bossy neighbor because it is going to tell your underlined number what to do. (Now students will use their rounding hill, which is the second picture that you see when you look at the sample slides I've included for you to see). Find the bossy neighbor on your rounding hill. What does it say to do? Stay the same. Therefore, 528 stays the same and everything past the underlined number becomes a 0. Now you have 5,280.
All of this is shown and written with animation on the PowerPoint.
There are 3 pages that can be printed and used with students. Slide 19 is the rounding hill that all students will learn to use by viewing the PowerPoint and will use it with their assignments. Slides 20 and 22 are worksheets for you to use to assess student success. Slide 22 also incorporates place value through the hundred thousands place. Students work to make a number given directions (ex: place a 4 in the ten-thousands place). Then they will write the number in word and expanded form before rounding it a few different ways.
I really enjoy making PowerPoints. If you notice any errors, please message me. If you have any trouble at all, please message me and I will so anything that I can to fix it. It may appear that things overlap but please view the PowerPoint before assuming something is wrong. It is more than likely the animation.
Please visit my store for other PowerPoints, including one on exact or estimate, where students learn how and when to estimate answers!
Thanks for looking!
