Rounding Task Cards

I've started my Place Value unit and one of the standards requires the students to round numbers to the nearest ten, hundred and thousand. I created some task cards to use with the unit.

How do you teach rounding? Share a lesson!

  1. I use rounding hills...it's a visual for the kids...all the 10s on the bottom of the hills an the 5s on the top. Once they learn the concept - then they can use it for however big of a number. Just as long as they know which place value to look at when rounding...I've even seen them draw the hills on BIG tests (which of course made me smile to see tht they remembered one of my strategies! hehe)

  3. It's simple, but we chant "5 or above, give it a shove! 4 or less, let it rest!" I've also used the hill strategy, which is definitely effective!

  4. Rounding is such a difficult subject for my kiddos! We made an anchor chart with the steps:
    1. Underline the place value you're rounding to.
    2. Circle the number to the right.
    3. If the number is red (0, 1, 2, 3, or 4) STOP and do nothing to your underlined number. If the number is green (5, 6, 7, 8, or 9) then GO ahead and add 1 to the underlined number.
    4. Everything after your underlined number turns to a 0.

    I've seen the hill concept, but I think my kids would get confused with that. If I use it, I might have 0, 1, 2, 3, and 4 flat and then have the others going up the hill. I think they might think round down and subtract one if they're all on a hill.

    Okay, I just took up your whole comment space...sorry!

  5. I use the rounding rap,
    Underline the digit (the place value asked to round to),
    And look next door (I have them draw an arrow),
    If it's 5 or greater gotta add 1 more (to underlined digit)
    If it's 4 and under just ignore
    Turn the rest to zeros that's what zero is for!

    The kids love it. I also have them work with partners and they roll dice. You could also use playing cards.
