Last Week Before Recess Week
Hi There everybody!
As this is the last week before your 1 week break, we are going to be devoted to the correction of the Math exam, specifically of the word problems. Remember that the most important part is the PROCESS not the result, so you have to keep working on the processes you use when solving a problem.
In case you wonder, you are not handing out the reading blog for this week either.
Have a good week and use time wisely!
Regards!
