This is a journal for a weekly estimation jar. Day one students write "I think there are __ in the jar." Day 2 you give students a "more than" clue. They write that down then write their new guess. Day 3 they are given a less than clue and then write their new guess. On day 4, you count the objects as a class and the student writes "In the jar there are ____." On the last day, they draw the correct amount in the jar. I print this as a booklet so each page is a half a page size.
