Review for Test

We have a test today in EDEL 433 and I am going to type a review for myself and that will be a blog.
(number of groups) x (the number in each group)= (total number of things)

The total is unknown= Grouping
--Mr. Gonzalwez has 4 bags of marbles. There are 5 marbles in each bag. How many marbles does he have in all?
TU=Grouping

The number of groups unknown=Measurement
-- Mr. Gonzalez has 20 marbles. He puts exactly 5 marbles in each bag. How many bags can Mr. Gonzalez fill?
GU=Measurement

Number in each group unknown=partititve division
--Mr. Gonzalez has 20 marbles. If he has 4 bags and wants to put the same number of marbles in each bag, how many marbles will he put in each bag?
NU=Partitive

In class we were able to "play" with different units and centers. One of the unites was measurement. The unit really focused on observation and estimation. Lots of hands on work in this math lesson. It also integrated science in it, which is actually very neat.
