Math Antics - Points, Lines, & Planes

Math Antics

Not to take away from Points, Lines and Planes but the Math Antics site is amazing! My Professor introduced Math Antics to us today in this video introducing Point, Lines, and Planes, which by the way is awesome!** I did find some great points, lines, and planes worksheets on google if your interested in doing some extra practice.

The best part of my day was when I went to my service learning and guess what the teacher was showing in class?  You guessed it a Math Antics video.  I was honestly very excited because I thoroughly enjoyed the video in class today so much, I need to show you both videos here.  I just love this site mathantics.com 

Talk about a great friendly site and wonderful videos to help you introduce different subjects that are so easy to follow along and gain information from.

The kids in Mr. Martin's 2nd grade class sat patiently watching the video, it grabbed their attention and kept them following along because of the way he included you by asking questions of the audience.  This was a very productive video.  Mr.Martin would stop the video and let the students work the problems out before the video did, he then would turn the video back on and the students could see the correct answers and follow along as the problems were worked out step by step.  It also gives the teacher time to look around and see who is needing extra support or struggling with getting the correct answer because the were not borrowing or regrouping properly.

See ya on the plane later,

Learned a New Word Today "Regrouping"

Today was my first day of service learning and I loved it!  I learned a new term and got to observe and help out a class of 2nd graders for a few hours today, total enjoyable experience.  I was in Mr. Martins second grade class today and when I arrived they were doing reading but shortly moved into math.  We handed out markers and whiteboards and Mr. Martin proceeded to teach them how to subtract 2 digit numbers, then 3 digit numbers.  The new vocabulary word or new term I learned was "Regrouping".  I've always called it "Borrowing" because that is what I was taught, I find it interesting to hear a new word being used and see it being understood by the students.
The teacher also used prompts like I do, we do and you do for the students so they knew they're expectations in class and could follow along with the tasks at hand.  I found this a useful tool for letting the students know what was going on and they seemed to need a little reigning in from time to time and I found that these simple words gave enough direction so the students knew exactly what to do.

**Note: I linked the word "Borrowing" above to the multi-subtraction video that we watched in service learning but I had already included it on another post because it was another day and the teacher showed that video that day. I just love the way Math Antics teaches you and explains everything in detail and simply.
Don't subtract me just yet,

Grab a Handful!

Professor hands you a box and says,"Grab a Handful!"  What do you do? Do you go small or do you really go BIG!
This was a great activity in class and it really showed us a good look into Measures of Central Tendency: Mean, Median and Mode. The measure of central tendency, in statistics, is a central or typical value for a probability distribution.  We had a class of 22 participants, we each grabbed a handful (cubes), the lowest grabbing 6 cubes and the largest handful was 22 cubes (by the way this is referred to as the Range).  We grabbed a total of 236 cubes all together in class.
A little Definitions:
Mean: Also called the average. Is best for numerical data without outliers.
Median:  The middle value of a data set when ordered least to greatest.  1/2 the data is above the median and 1/2 the data is below the median and is not affected by outliers.
Mode:  The most frequently occurring data point in the set.  Can be used with categorical or numerical data.

Now we find the Range of data by subtracting the least amount from the greatest amount of cubes grabbed which gives us a Range of data that is a 16. Most classmates had grabbed 9 cubes which is the Mode in the set. The value in the middle of the ordered set of numbers is the Median which was a 10 for this data set.
We did this activity in class with cubes and we all chose our own cubes and grabbed what we wanted.  Our Professor then set us loose to find other students with the same cubes and then set us loose again to find the median of the cubes, classmates were setting up in groups of 9,some trying to give away extra cubes and what we realized was the Median was 10 not 9 but it was a fun realistic activity to do and a great break the ice activity into measures of central tendency.
I had to share this video since I have a new love for Math Antics and it does a great job at describing all you need to know to get you rolling with Mean, Median and Mode! Also check out Central Tendency  at A Maths Dictionary for Kids  Jenny Eather has a great resource for teachers that is AMAZING and its for all Mathmatics check it out Jenny Eather Resources

Leave to Sammi to go big with a huge handful of cubes Lil Miss 22, *just teasin*,
