Understanding Arrays
factor x factor = multiple (product). The first couple of times we explored with arrays, we had the dimensions facing up (like in the picture below). Given those factors, friends had to figure out the product. They used different strategies in order to help them solve the problem. We noticed many things. One thing in particular was that square numbers can easily be defined as a number that has a square array. In order to have a square array, the dimenions (factors) have to be the same number. The 6 x 6 and 7 x 7 arrays show the square numbers 36 and 49. We explored with array cards again last week, except this time we had the product facing up and had to figure out the dimensions. Not only did we have to know the factors for that product, but we had to eliminate ones that would not make sense based on the shape of the array. For example, for 42, we know that 42 definitely has the factors of 1 and itself. However, we know that 1 x 42 or 42 x 1 array would not make sense at all when looking at the rectangle in the picture below. As friends were working, I noticed a few groups who came across 49 and 42. This was definitely something to talk about in closing meeting. They said from practicing their multiplication combinations and seeing that 49 is a perfect square, they know the dimensions must be 7 x 7. When trying to figure out the dimensions for 42, They put 42 on top of and then next to 49. They realized that 42 and 49 have the same number of columns but a different number of rows. Some explanations from the kids were:

Explore Learning: Gizmos!
Over the past two weeks we've learned lots of cool things like:
a) All rocks are made of minerals
b) Over 3,000 minerals have been identified
c) Minerals can be identified by testing their physical properties (color, luster, streak and hardness)
d) A Diamond (Miss Donofrio's favorite) is the hardest mineral :)
We observed and collected our own data with about 7 types of minerals in class. Friends really enjoyed the hands-on experience. Because we didn't have a huge variety of minerals, we brought in some AWESOME technology to help us out.
explorelearning.com is a website that offers something called 'Gizmos.' Gizmos are online simulations that power inquiry and understanding of Science and Math. The screen shot below shows just a glimpse of our 'Mineral Identification' Gizmo. With this Gizmo, my friends were able to explore 26 different minerals and test all the physical properties with just a few clicks of a mouse! I was impressed with how REAL this virtual experience felt. We collected a ton of data and reached the conclusion that the only way to really identify a mineral is to test all the physical properties. What's really great about this website, is that each friend in my class has a username and password and can access the Gizmos in and out of school. After exploring with the Gizmo for a couple of days, minerals started flooding backpacks and friends couldn't wait to share one they just found or one that had been taking up space on their shelf for years. I feel great because I know how much they got out of the experience and how now they look at something as simple as a rock or mineral very differently than they did just two weeks ago. :)
