Week of September 24
We have moved on to learning about Fractions, Decimals, and Percent. In this unit we will cover many different curriculum outcomes including comparing and ordering fractions, benchmark fractions, equivalent fractions, repeating and terminating decimals, as well as converting fractions to decimals and percent.
It is important for the student to understand that a fraction represents part of a whole. There are two parts to a fraction. The numerator (represents the part) and the denominator (represents the whole). Below are two introductory videos we've watched which will help re-enforce what a fraction is and it's parts.
Through a class discussion the students have provided many real life examples of places we use fractions, decimals and percent in our daily lives. Some examples students came up with were: marks for school, baking, clothing tags (ie: 100% cotton), weather (ie: P.O.P of rain 20%), money (ie. $0.25, $0.50), road signs in the USA (ie: 1/2 mile to exit), sales (ie: 30% off). We've discovered that fractions, decimals and percent are all around us and we work with it on a daily basis so it is important that we have a solid understanding of these concepts. Students need to be comfortable using this language and being able to convert from one to another as they all are connected.

Today we began a discussion on Benchmark Fractions. They are the most commonly used fractions and include fractions such as 1/2, 1/3, 1/5 among others. It is often helpful when talking about fractions to make a monetary connection. For example, 1/5 is like having $0.20. Check out the definition and where these fractions can be found on a number line by clicking the pdf document below.

Week of October 1-5
Students have been learning how to convert a fraction into a decimal and vice versa. This week we will continue to work on this. Students will be learning how to simplify fractions and will be learning about equivalent fractions. Below you will find some notes and videos which may help re-enforce what we've learned in class.

Check out this Numberline Battleship game. Students are challenged to place their ship on the correct spot on the numberline by clicking on where the fraction can be found between 0 and 1 on a numberline. Good luck and have fun!

We will now start working on addition and subtraction of decimals. One of the biggest problems students have when adding and subtraction decimals is that they do not line up the decimals nor do they add zeros as place holders. Below you will find several videos which will help re-enforce the importance of this. Students sometimes stuggle with subtraction because they often write the smaller number on top and try to subtract it from the larger number. This is incorrect because you can not subtract a larger number from a smaller one and get a positive value.
Ways to help at home:
Students are generally very good with money so as much as possible, I try to use money when working with fractions and decimals as they can make a real life connection to it.
1. Have your child help you create a grocery list and go through the flyers with them. Choose a few items and have your child ESTIMATE the cost and then have them ADD up the actual cost. (don't forget the $ sign)
2. Take step 1 a step further by asking them how much money they would get back from the cashier if you gave them __________ dollars. (don't forget the $ sign)
3. Practice having your child write down different decimals to ensure they are putting the largest number on top, the second largest number next, etc (ex: 23.53 + 17.2 +3.012 + 0.27) Have them look for places where "0" can be used as a place holder.
4. For subtraction of decimals have the students think about a bank account and if they have $25.00 in the bank and they buy a shirt for $17.99 how much money would they have left. Remind them that they must have the largest number on top because you can't take $25.00 from $17.99 and get money back.
5. Have the students create their Christmas list and ESTIMATE the cost of their choices and then find the ACTUAL COST it would be if they were to purchase all of the items.

Multiplication of Decimals - We will now begin MODELING multiplication of decimals using base 10 blocks. Traditionally we would use a flat (a square which reprents 100) and a rod (which represents 10) and a unit (which represents 1) however; the values of these pieces change when multiplying decimals.
The Flat will now represent 1, the rod will now represent 0.1 and the unit will now represent 0.01
Please see the pdf document below for models and steps on how to multiply using base 10 blocks.
