Rounding Strategy + A Free Printable
So we have been plugging away at place value and last week we tackled ROUNDING!
Is it just my students, or does is rounding sometimes hard for kids to grasp?
I use many strategies to help my kiddos with rounding
but this is usually the first strategy I teach.
It starts with a story, because who doesn't love a story!
I tell them that numbers don't like to just hang out on a line.
They actually LOVE to ride roller coasters!
I draw the number roller coaster on the board.
Then of course, the story has a plot twist and the roller coaster loses electricity!!
We talk about gravity.
(insert teacheable moment here)
I love when I can squeeze one in!
We discuss about how the numbers 1-4 would fall back to the starting point and numbers 6-9 would fall forward to the next 10/100/1000....you get the idea!
Then we talk about the number 5.
Since it's half way in the middle....it get's to lean forward and go down the roller coaster!
We usually hold our hands in the air and pretend to ride the coaster!
I've actually taught this "trick" for several year but this year
I made rounding roller coasters for the students to use!
They really loved them!
I laminated them so students can use dry erase markers on it.
As you can see, my little sweeties was rounding to the 100's place. Still works!
(don't mind her middle finger...lol! Didn't realize this till after I took the pictures)
It also includes a couple of worksheets to practice rounding!
My kiddos have finally grasped the concept of rounding with this technique!
What rounding strategies do you use?
