I had recently done a rounding post (which you can see here), but going with my new theme of a CCSS for MaTh it rounding happened to come up again. Here is 3.NBT.A.1--Use place value understanding to round whole numbers to the nearest 10 or 100.
Since I don't have much time or energy for coming up with a new activity I just have some suggestions...
- Show things visually (use manipulatives or for a change try using food--like raisins, grapes, etc.)
- Put the ones into little bags of tens, then once you have ten of those put it into a box of a hundred.
- Have fun playing with money in a pretend store.
- Have the kids play a game similar to duck duck goose where there is a kids representing the ones, one representing the tens and another one for the hundreds. They have cards in front of them and they pick a random digit. When two kids go around and eventually one says "round" and the other will say "tens" or "hundreds" the kids sitting raise a digit then the first child standing to shout the correct answer gets a point and sits down. The one who needs more practice gets to keep playing.
Also, over at Math Coach's Corner she had a number line rounding post that was excellent!
Now it is your turn to link up! Have a happy Thursday!
