After today’s successful classwork with multi-digit numbers I feel we are ready for more complex multiplication problems.  Tonight’s video is long (about 10 minutes), as Sal uses many examples to review the topic.  Be sure to watch the entire thing.  Remember, I’ll know.

Do exercise Multiplication 4

After the completion of today’s Place Value Assessment we move into the study of Multiplication and Division.  Tonight’s homework is meant as a review of previous skills.  Take it seriously, and try to complete with minimal errors.

Khan Academy Homework-

Watch video Multiplication 4 then complete the exercise (Multiplication 2) that goes with it.

Here is the link to tonight’s homework:

Don’t forget to complete the worksheet as well.

Estimating is the last skill we need to learn in our first unit.  The video on this can seem complicated at first so I would like to offer a few bits of advice.

1) When estimating, always round first!  Do not round after you solve.

2) When Sal refers to nearest whole number, this is the same as saying “ones place” or “unit.”  They are all synonyms. 

3) Do not forget about the digits to the left of the place you are rounding to.  They remain the same (unless you are rounding a 9 up).

Estimation with Decimals Video – Be sure to log in prior to watching.  Complete the exercise that follows.  You will probably need to use scrap paper.

 Enjoy.

We will be having our first math unit assessment, place value, the week of October 3^rd, on either Tuesday or Wednesday.  Below are the skills which will be assessed in this exam.  Every one of these skills can be reviewed in your text book or on the Khan Academy.  Also, be sure to look over quizzes 1-1, 1-2, and 1-3 as well as all the homework worksheets.
