Hello all
If anyone has a poster/anchor chart that helps children find the nearest ten, can you please post it?

Thanks!

I always have several kids that just aren't developmentally ready for rounding in 2nd grade. I think a visual chart will be a help.
Thanks for posting.

I agree that visual are very helpful for many second graders. I have better luck with number lines, though. I've noticed a lot of kids have trouble understanding why 12 is closer to 10 when you have to go up a line... When I use a 100 chart, we move spaces like we're playing a board game and count how many we have to move back and how many we have to move forward to decide which is closest.

I've also had many kids who seem to just pick a random multiple of 10 to round off. We've been talking a lot about how the lowest possible 10 is part of the name of the number, and the other choice is the next 10 up. For example, if we're looking at the number 36, we can hear that 30 is part of the name of the number so that count by 10 is one of the choices. The next 10 -- 40 -- would also be a choice. Then we look, count, or try to apply the "5" rule to decide which one to use. Hopefully that makes sense.

Thanks for the chart. I have some children who are having problems with rounding. This will be a great help. I am thinking about reducing the size of it and putting it in each child's desk folder.

rounding chart

I use a chart similar to this, i shrink it to make it smaller, then use a sharpie or something that will make a dark line down the middle, then laminate and tape to their desk, that way it is there for them. I have also used the clear colored tape and divided a larger hundreds chart that is hanging up, they will then have the smaller one on desk and the larger one at the board.
