Rounding to the Nearest Ten or Hundred
Most third graders start the year with learning how to round to the nearest ten or hundred. For most, rounding to the nearest ten is a review. But if it isn't for your class, a great way to introduce this concept (or review it) is to project a number line 0 to 10 on the board, or even, if your projector is flexible, on the floor. I have included this number line, online or if you click on the picture, you can print a permanent copy in the free resource I've provided

Give your students, one at a time, an index card with a number, 0 to 10, on it. Have the student come to the front of the room, card in front of them and stand at the number. Then they need to hop, skip or just walk to the number that is closer 0 or 10. Let everyone have a turn, then if you have time they can create a 60 to 70 or 80 to 90 number line on paper and you can project their image for the whole class.
Why Teach Rounding?

Once your students have a solid foundation of rounding up or down based on how close they are to 0 or 10, you can introduce the rule: 
  • If that digit is 0, 1, 2, 3, or 4, you will round down to the previous ten. (Or in the case of zero, the LACK of a ten.)
  • If that digit is 5, 6, 7, 8, or 9, you will round up to the next ten.

Next, I have included rounding charts, for your overhead, center reference chart or an anchor chart. You can even print and laminate a copy for each student and use them year after year.

Give the students any type of counter, coin, unifix cube, etc. and call out a number. Let them slide to left or right depending on HOW CLOSE they are to 20 or to the 30.

Next, reintroduce the concept, but with 0 to 100. I've included a a chart for rounding to the nearest hundred by tens, but you can give a child the number 324 and have them point between 320 and 330 to teach them in rounding to the nearest 100, the ones column doesn't factor into the rounding, they only need to look at the tens column. This concept might take longer, so call 418 and have them slide their counter to 400 or 500. Then call 481 explaining that then numbers might look the same, but that they need to pay close attention to the tens column. These charts can also be used for circling the number and creating their own arrows to the answer.
