Welcome to Mrs. Harrington's Fifth Grade Math Page

Fifth grade math is a lot of fun, and I'm excited about the coming year.  All fifth graders in the Campbell Union School District learn using the Expeditiary Learning curriculum.  There are six modules.  This website is very informative:


Another math resource used at Rolling Hills is the on-line IReady program at  https://login.i-ready.com.

Good afternoon!  Our homework tonight is a page with decimal numbers (decimal fractions) that need to be expressed in expanded and unit forms. We did the first together:

199.007  would be

expanded:  (1x100) + (9x10) + (9x1) + (7x 1/1000) 

unit form: 1 hundred 9 tens 9 ones 7 thousandths

The poster we made in class that can help with this is posted on Google Classroom.

We started PEMDAS today with expressions such as 7x (7squared +1).  Please review this tonight.  

Be sure to have a great dinner, great time with your family, and a great night's sleep.  See you tomorrow!

Today we finished up our group posters on the different forms of numbers.  I will post a picture of one resource we used.  Tonight's homework is on rounding numbers, pages 39 and 42 in our workbooks.

Have a great night!

Welcome to the Math Homework and Information Page!  Check back daily for updates.

Today we discussed the first module test, which is scheduled for September 27.  We looked at the math concepts we have already learned and those we still need to study.  Most students are comfortable with using a place value chart to multiply and divide numbers by powers of 10 (the magic number in fifth grade math :-).  They are comfortable with conversion factors when using the metric system, especially with meters and centimeters, kilograms and grams, and liters and milliliters.  We just started using place value charts to compare the values of decimal fractions.  We have also done lots of interesting word problems.  Fifth grade math is so much fun!  

We listed math concepts to cover still before that first module test, including flexibility and fluency with standard, word, and expanded forms of numbers, multiplying, dividing, adding, and subtracting decimals, estimating and rounding numbers to a specific place value.  Funny- I don't remember doing such great stuff when I was only in fifth grade... :-)
