In my exploration of decimals, I learned that I have
been reading/speaking decimals incorrectly. One of the points that the text
makes is that when reading a decimal such as 0.34, we are to read it as
thirty-four hundredths. However, I have always read it as zero decimal (or
point) three four. According to the text, this is the improper way to read
decimals. By reading it the way I do, I am slipping away from the understanding
of decimals being an equivalent of a fraction. As I reflect on how I read
decimals, I think about the example the text gives about reading money. Now, I
am left to wonder if this is where I began reading decimals incorrectly. Hopefully
now that I am conscious of this error, I will be able to correctly discuss
decimal values.
These tools will be useful in my educational
activities because it has to do with self-reflection. Prior to reading these
chapters, I would not have realized that I was reading decimals incorrectly. Therefore,
I can use decimals and fractions combined in educational activities to teach
students how the two relate. This may help students learn one concept more
quickly once they grasp the other, as well as teach students the proper way to
read decimals.
The uses of fractions and decimals are to describe
something that is being divided into parts. There is help available online for
students to learn how the two relate. My investigation involved exploring Great
Games, which is an online gaming site that helps students solve mathematical
equations for different units. I explored “Puppy Chase” which involves the
computer showing you a fraction, and you would have a multiple choice question
where you have to determine what the decimal value for the fraction is. I envision
using the tool as a math refresher to contribute to my work in building my
mathematical knowledge.
Furthermore, I explored further into Great Games
after attempting a game that another student found online. This game is called “Meteor
Multiplication”. The game deals with meteors that have multiplication questions
written on them. The missile that blows up the meteors has an answer written on
it. For each answer, you have to blow up the meteor that has the multiplication
equation on it. This is a useful tool that you can use in an educational
activity because it teaches students how to use mental math. Due to the nature
of the game, you only have a limited amount of time to blow up the meteor
equation. This does not leave time to use a calculator or use pencil-and-paper
method, therefore forcing game players to utilize their mental math skills. Therefore,
this game can develop a student’s mental math abilities, making this skill set
stronger.
Lastly, the text reveals different principles and
algorithms for both units. This is beneficial to learn and reflect on as a
future teacher because it teaches you that there are multiple ways to solve
mathematical problems. Some of your students will solve mathematical problems
differently than others, and the text reveals the different ways of problem
solving. In addition, understanding the differing principles and algorithms demonstrates
a gain in your mathematical knowledge because it shows an understanding of
whatever unit you are working on.
