Finding Expressions

Good Morning All!
I am excited to share some of our math thinking we've been doing this week. I have to say, I love technology, especially when it works and having WiFi in my room. 
I asked the student students to bring in their iPod's yesterday so they could video tape each other finding expressions in their images they've created. 
Here is a really nice example of Mackenzie finding a mistake she made, and if you look really closely you'll see I marked the mistake correct. Oops!!!
She is showing you how she can see the expression 60 - 3 (she's written 60 - 4) in the drawing she's created. 

You'll see she realizes she's made a mistake and pauses. I think she takes some time between videos to think about her mistake, work it through in her brain and re-records her thinking. Here she is.

I LOVE that she realized her error and then they redid the recording. She's very confident in her thinking and retelling of what she's done. Today, I feel like we are getting some place, tomorrow, well... we'll see. I'll take what I can get.
Have a great weekend everyone. If you have some thoughts on her thinking or you're wondering why I'm having them find expressions in the images, drop me a line.

Waterproofing and Insulation in Penguins.

Did you know waterproofing is, keeping something from getting wet? Penguins have oil on their tiny feathers to help keep the water from making them wet all the time. The oil helps to keep the layer of down underneath their top feathers dry. When our hands went into the water with the Vaseline/oil on them and we pulled them out, water droplets formed on top. The water didn't soak into our skin. 

Insulation on a penguin is the blubber/fat we don't see because the feathers and skin are on top. The blubber/fat keeps them warm so when they go in the cold water it keeps them nice and cozy. The blubber/fat is very thick and heavy. 
When our hands went into the blubber glove, it was warmer on the inside of the glove than it was with our hand just in the water. Blubber and fat are squishy.

Look at how the droplets form on top of our hands.

Trying the blubber glove. Which do you think is warmer, the glove or the hand going in the cold water?

Forts and Floats

Here are some pictures of the transformation the classroom went through when we celebrated Family Literacy Day. 

Hope you enjoyed them. I'll be back soon. I promise.
