Fraction/decimal relationship
This week I wanted to start looking at how fractions and decimals are related. I came across an interesting lesson plan at www.education.com that I thought would be really helpful. It is a lesson plan for 4th grade math.
The lesson begins by engaging students in a discussion about nicknames. Then you ask whether or not calling someone by their nickname changes who they are. You can relate fractions and decimals by explaining that they are both different names for the same value.
The lesson I looked at stuck with denominators of 10 or 100, that way they can use base 10 blocks. So, when you show the students the fraction 53/100, you would explain to them that you would use the numerator to fill the tenths and hundredths places to get 0.53.
The lesson included a group activity using a deck of playing cards. The students are put into groups of 3 or 4 and they need to split the deck into face cards and number cards. The kings are equal to 10, the queens are equal to 100, and a jack is wild (10 or 100). The number cards are used for the numerators. Have the students write both the fractions and decimals they pull from the deck in their math journals.
I liked that this lesson utilized the base 10 blocks we have been speaking about in class. I felt that this was a really good way to explain it - as well as activating the students prior knowledge of fractions as well as place value to explain decimals.
I completed the worksheet that accompanied this lesson plan.

I really liked this lesson plan! I especially found it an excellent idea to start off the lesson by comparing nicknames to fractions and decimals. Such a clever idea! It really drives home the message that both values are the same, but just written differently. I also liked the activity you were able to find in regards to this lesson. Students like to play and what better way to play and also learn at the same time. I've seen a couple people use the website, education.com, and am definitely going start looking into this website as a resource tool.
