Prime and Composite Numbers

Yesterday and today, in the midst of banging hammers and nails while working on our lanterns, we learned about prime and composite numbers. Before learning about this concept, we needed to review what factors and products are. Here is a link to a presentation that we looked at that helped us to better understand these concepts. This may be helpful to review later for a quiz. Please feel free to download, save, copy and distribute these presentations any time. They are being made to be used. The more people they can help, the better!

On another note, we are almost finished our "How to" brochures. Tomorrow, we will begin building an anchor chart for our next skill, Analyzing, which basically means finding facts in a text. I will post a presentation and anchor chart for this when we build it in class. We will be reading a book about Cheetahs, and a magazine called "Power Up", which is about electricity use. We will be writing a information report at the end of this unit.
