Can you guess how many are in the Estimation Jar?
Each student in each class each month will guess how many items are
in Ms. Trostle’s estimation jar. Every month will be a new jar to
make an estimation. The winner from each classroom will be given a
pencil and an opportunity to make a guess at the BIG ESTIMATION JAR
that will be displayed by the office. Every student will have one
opportunity to guess at the BIG JAR, but they can earn bonus
guesses by making the winning guess in the classroom for each
month’s jar. The BIG JAR winner at the end of the school year will
win a $10.00 gift certificate for Walmart.
