Rounding Anchor Charts

Hi, friends!  Hope everyone had a great day at school!
My kids and I were discussing rounding today and we came up with these anchor charts.
I wanted to have this mini lesson and anchor charts in place before the kids jump deeper into other activities and lessons involving rounding (to the nearest ten and hundred).
How do you teach rounding?!

    I always teach it your way and the roller coaster example… I found this one online last year and loved the idea. Think I will try it this year!!

    I also use a number line and discuss "benchmark numbers"…key term for them for later! πŸ™‚ I did watch a cool lesson on Kahn Academy for rounding!

    Our 3rd grade team found a Common Core lesson/game to help out with Rounding instruction! I blogged about it here:

    I use both a number line and a roller coaster! We also practice rounding numbers nearly everyday as part of our morning maths! We want lots of practice!!! Great anchor charts!

    Great anchor charts! I love to use the number line and we also use a rounding hill. Basically, it's your drawing but we lead in with this huge story about driving a car and stopping at different towns along the way. The problem is…we NEVER remember to put on the break. Ooops! Our car starts rolling…which way will it go? The more you ham up the story the better. πŸ™‚

    I love that your charts are done with your students!! We use the number line, hill, and a fun little technique pretending they have a balloon in their hand. If the number ends in a 1 they put one finger out, 2 they put 2 fingers out…and so on until they get to 5 which will then release the balloon (and the balloon will go up) which means they need to round to the next higher ten. I hope this makes sense. I bring in a couple of balloons and have the kids practice. If they haven't let go of the balloon, they have to stay at the 'lower' ten. Have fun!!

    I love your anchor charts for math! I need to do more of these.

    One unique thing that we do is a math notebook. The students include a what they already know, lesson objectives, proof (example), reflection and finally, a traffic light rating of how well they understand the concept.

    We also use the roller coaster idea to teach rounding. We have sound effects: "click, click, click" for each number as we climb up the roller coaster… then a sad "woooo" if it doesn't make it up…. or a joyous "Wheee!" if it makes it over the hump.
    I also played "Hawaiian Roller Coaster Ride" from Lilo & Stitch to get them excited about our math lesson that day.
    We also watch the BrainPop Jr. video on rounding.

    I have a blog post on my math journals here: Teaching Happily Ever After
