Math

We are finishing up our unit on numbers to 100. A big part of this unit is learning to estimate and use an appropriate referent. For example if there are about 50 objects or less, we would choose 5 as a referent. We count out 5 of the items, see about how much space it takes up or how much it looks like. Then we quickly eyeball the items and count by 5s. For amounts that we think are over 50, we use 10 as a referent.
After estimating then we must correctly count the amount of items. Students are encouraged to count by 2s, 5s and 10s- grouping the items as they go. If they are counting a larger amount of items and are counting by 2s, I encourage them to count by 2s but put them into piles of 10 as they count. This way if they get mixed up they don't have to start all over again- they can just recount the piles of ten which is much faster than recounting by 2s.

Also in this unit is being able to represent numbers to 100 in a variety of ways-particularly looking at the place value. We had an example in our agenda the other day.

I hope this gives you  a better idea of what is expected at this grade level.
