7th grade student writing about similarity and congruecy

Similar Figures are figures with the same angles therefor the same shape, but a different size.  The Scale Factor is the number you multiply or divide by to make the figure either bigger or smaller.  Congruent Figures are figures that are the same size and shape. To scale up is to make the figure bigger and to scale down is to make the figure smaller. Scaling up is multiplying and scaling down is dividing.  Multiplying an dividing are the only two things you can do to make a similar figure. The youtube video on Scale Ella we watched in class really helped me. Also, the pictures of Homer and Bart Simpson you put on the smartboard as well. I think I really understand this well.

7th grade student pre-writing about negative numbers

What I Know About Negative Numbers

I know that negative numbers are less than zero. I know it sounds crazy. What number could be less than zero? Well, when I was little, im not sure how little, but it was before 3rd grade, my dad read me a story in a kids magazine about the origin of zero(I know, my dad's like, a total math freak right?) and it said things like what number systems were like without zeros, blah blah blah, and it mentioned negative numbers in passing. I was confused, so dad said "Think of negative numbers as a vacume. Look, if I turned this glass over on the kitchen table (demonstrated with glass) and there was nothing in it, that would be like zero. Now lets say I took a vacume and sucked all the air out. That would be like negative numbers, because they suck up positive numbers." Later on, I noticed a number line in the math room that not only showed positive numbers, but also negative numbers. Looking at the number line, I decided that negative numbers must be the same as positive numbers, only with a negative sign next to them. Therefore, -2 + -2 must be -4, just like 2+2 is 4. Then I read in a book (I think the book was Things Not Seen by Andrew Clements) that any negative number time another negative number equals a positive number. Those are the things I know about negative numbers.

Sleepy students

Maybe we should have class @ midnight, and they would be awake. Compare and contrast these poems (Due by end of class)
