CBF X


On Friday, our MWF students tried to estimate the number of boxes that make up our fort.  Estimating is hard for young children who are just beginning to understand number concepts so we introduce estimating and practice in a variety of ways.  We want them to understand it's a 'good guess' and not a 'cuckoo crazy' guess.  I started off asking if there were a million boxes.  Too big or too small? Too big.  I next asked if there were ten.  Too small!  Eventually we worked our way to the hundreds and moved closer to the actual number of boxes. How many boxes in the CBF X?

373
