We have now finished up week 11 of math class and yet again,
I am amazed at the various ways in which we can introduce mathematical topics
and procedures to our students. It is my
goal to try and make math interesting and exciting, as I hope to change the
negative perceptions about mathematics, to positive ones within my classroom.
In class this week, Pat brought in a jar filled with Oreos.
I was immediately intrigued because I knew that we were about to engage in a
fun activity that involved food. For this
activity we were supposed to use estimation to make an education guess on how
many cookies were in the jar. We passed the jar around the class and people
came up with their own unique strategies on estimating how many cookies were in
the jar. Some people counted the cookies on one face-side of the jar and then
used multiplication for the other sides of the cube to come up with an answer.
Others, estimated how many Oreo’s came in a pack and tried to use that total to
determine how many packs of Oreo’s Pat had added to the jar. Those are just
some of the many strategies students used to come up with a number. Once
everyone came up with their estimation, we placed our answers on a stem and
leaf plot to visually see how our data was collected. Through this data, we
could see the statistics of all of our numbers, such as the average number, the
median, and the mode. I think that this activity was great because we use
estimation all of the time in our daily lives and sometimes I think that we
don’t even realize that we are doing it. I think that it’s important to show
our students the many ways that we use estimation in our daily lives and give
them useful examples like this.
Data collection is an important skill to possess. The
textbook discusses the importance of organizing and sorting your data and
creating appropriate questions when collecting your data, so that you gather
your information in the best way. The image below shows the use of linking
cubes to looks for patterns, make predictions, make comparisons, and make
decisions. In class we have used linking cubes a lot to work through
mathematical problems. I think that manipulatives such as linking cubes are a
great way for students to engage in data collection because they are able to
physically see and work with the different types of data that these cubes can
represent.
While browsing YouTube I found a fun and interesting video
about Yoda and how he is teaching young Luke Skywalker to have a grown mindset.
In the video Yoda tells Luke to “unlearn what you have learned”. Luke replies
saying, “ Alright, ill give it a try” and Yoda says “ No! Try not! Do or do
not! There is no try”. This scene is very relative to my experience in our
class thus far. I feel like I have had to unlearn some of the “old” ways of
math and I have had to have a growth mindset to tell myself I can do this!
Very good blog post Kevin! I enjoyed your thoughts on how different manipulatives could teach students with probability. I feel that these are very helpful for students because they can physically work with math. I also liked the video you posted, not just because I am a star wars fan, but is a great example of how a growth mindset can change your perspective on challenges.
