Welcome to my math blog! The purpose of this blog is to help you stay informed about our learning and experiences that have taken place during our math class. I have also included links your child (and you) may want to use in order to supplement math learning in 5th grade.

Math About Me (Day 2)

Today we began by shading in our square for day 4.  We found the decimal (.04), the equivalent decimal (.040), the fraction (4/100) and then found the factors of 4 (1, 2, 4) to help us determine if we could simplify (divide) or if we needed to create an equivalent fraction (multiply).  Once we discovered the factors of 4, we were able to conclude that 4 is a composite number (has more than 2 factors).  We were then able to locate the greatest common factor of 4 and 100 (4).  The conclusion was that we could divide both our numerator and denominator by 4.  We panicked a little when asked to divide 100 by 4, but relaxed when we realized that 100 is like money.  If we have a $1.00 and exchange it for four coins, each coin is worth $.25.  Therefore, 100 divided by 4 is 25!

Our new topic today involved converting measurements.  We needed to find out how many ounces are in 4 lb 6 oz.  We did this by creating proportions.  It's a little hard to verbally explain, but you can see the example and how we solved it.

Finally, we worked with a t-chart, coordinate plane, and algebraic expression.  We discovered that you can discover the pattern in a t-chart, and write the pattern as an equation, and use the t-chart as coordinates to place on a coordinate graph.  Basically, we used a t-chart to create a number line!

We were able to work on our Math About Me projects, but were unable to complete them.  So... WE WILL finish them tomorrow!!!  I can't wait to see them on lockers!

We also gathered data about the student's favorite restaurants in Hamilton.  We will use this information to create a graph at the end of the hall.  The data will be used next week to determine range, mean, median, and mode.

There is no math homework this evening.  However, starting next week, expect to see more assignments coming home in math!

Also, we will be having a Parent Meeting on Tuesday, September 10 at 6:00 in the Elementary Cafeteria.  Not only will we be discussing The Outdoor School trip in October, but we will also answer any questions you may have about your child's year in 5th Grade!
