What We're Learning this Week (November 5-9, 2012)

In Math on Monday, we began our second unit covering fractions. We started by discussing how to find equivalent fractions (by multiplying or dividing BOTH the numerator and denominator by the same number), as well as using fraction models to help illustrate their equivalency. 

In Science, we began discussing the types of rock and how they form: igneous, sedimentary, and metamorphic. We also learned a new song! (See the above post!) 

Wednesday in Math, we began studying factors, multiples, and prime and composite numbers. We discussed that a number has to be either prime or composite. Prime numbers have only two factors: 1 and the number itself. Composite numbers have more than two factors. 

In Science, we completed a Mystery Mineral investigation. We became "Experts" at investigating the physical properties of specific rocks. Then, together as a class, we had to figure out what type of rock each of our mystery rocks were, based upon their characteristics and attributes. Below are photos of us testing the color, streak color, luster, hardness, texture, whether or not it contains iron, and whether or not it contains carbonates.
