Common Core in Action Part II


I recently wrote about the video series I created for Pearson, entitled Common Core in Action.  I wanted to share one more screen shot from the videos and talk a little bit more about what using Hyperstudio can do to make videos more engaging and visually appealing for students.

Here is a screen shot from the video entitled “Common Core In Action: Adding Fractions”.


The screenshot above is showing the portion of the video where I am adding two fractions with a common denominator of sixths.   The sixths are visually represented by purple one-sixth fraction strips.

I used Hyperstudio to create the stage for my video because I can move objects around the stage during the video.  In this case, I used the stack of one-sixth strips on the bottom of the screen to show two-sixths plus five-sixths as adding a set of 2 purple one-sixth strips and 5 more purple one-sixth strips to obtain 7 of the purple one-sixth strips.

The point in the video where this screenshot is taken, is where I am showing how the improper fraction seven-sixths, can be turned into a mixed number by bringing a red strip to the stage, which is worth one whole.  Lining up the purple one-sixth strips along the edge of the red one-whole strip, I am able to show that 6 of the one-sixth strips are equal in length to the one-whole red strip, leaving me with 1 one-sixth strip left over.  Having the ability to move around the fraction strips during the video makes it easier to explain visually why seven-sixths is the same as one and one-sixth.

Using the fraction strips is important to the Common Core Standards for explaining WHY a common denominator is needed when adding fractions, and not just having the student perform an algorithm by showing them “how” to add fractions.


To give you a better idea of what the fraction strips can do for students when I use them in fraction lesson videos, I created a small video where I move around the fraction strips showing how to visualize equivalent fractions.  You can see that HERE.

In the screen shot above, I have created all of my fraction strips so that they are relative in size to the red one-whole strip.  For example, it takes 2 of the one-half strips to equal the one-whole strip, 3 of the one-third strips, 4 of the one-fourth strips, and 6 of the one-sixth strips.   Another reason I use Hyperstudio, rather than real fraction strips and a document camera to create the videos I teach with, is because I can create any size and color fraction strips I want.

If you would like me to create a lesson for you, please send me details about the manipulatives (like fraction strips) you would like me to use, along with desired colors, and I will design and create a personalized video lesson for you, on demand!


Summer Projects for Visual and Interactive Math

Visual Interactive Learning
I have been sitting here staring at my computer for the past week since I got back from an amazing time with a room full of extremely innovative teachers in San Francisco as part of the Livescribe Educational Advisory Board.

I keep staring at it not being able to decide where to start!  I have so many new ideas that I want to implement for the Fall, and now I have even more resourceful people to guide me when I get stuck!

Some of the big ones on my list I have already started working with, but I want to dig deeper and create projects for my students to interact with, and also projects for them to create:

Hyperstudio5 (Roger Wagner will be at ISTE this summer, so that will be fun!)
Livescribe (new cool stuff coming next week!!)

The newest application I want to learn:

I have been playing with WolframAlpha for the past year, but I recently purchased Mathematica and I am excited to see what I can create with it! My goal is to create visual and interactive materials for Algebra and Geometry.    I will post as soon as I start building!  I am still watching the video tutorials for now.   I want to look further into the following links as well:

Wolfram Research STEM Initiative

Wolfram Faculty Program

Lastly, I NEED to learn Photoshop.   My oldest son currently creates all of my artwork for my projects, but in a few years he will be off to college and won’t be around to help me!

Hopefully between spending time with my family and attending ISTE and HI-TEC this summer, I will be able to dig deeper and create some projects for next Fall using some of these great interactive applications!


Learning to use Camtasia (by TechSmith) – a great way to record my desktop!

I just downloaded Camtasia for both Mac and Windows.  I happened to be on my Mac when a student emailed me with a homework question, so I thought I would respond and try out Camtasia for Mac at the same time!   Here is the result.

I still need to learn to edit the video and add cool comments and arrows and all the other great stuff I “know” Camtasia can do.   But I am willing to go ahead and share my very first screencast with you to show you how easy it is to get started!

I finally have my OWN domain so that now I CAN embed Flash!  * added May 10,2010
