In class today we briefly reviewed estimating decimal sums. Then we discussed finding decimal sums and differences. We then segued to an activity on "Grocery Store Decimal Math". We were unable to finish this activity in class so I assigned its completion for homework tonight (due 12/4/08).
*Optional Extra Work
Estimate what is would cost to purchase all the items necessary to make a Thanksgiving meal. Check your estimate by comparing actual costs on grocery store receipts.
