Homework and class notes

Homework for Friday 9-16:  From page 31, items b, c, d, e, f, and page 32, items a, b, c, d, e, f, choose three equations to solve.  Be prepared to show your work and explain your answer in class.

Today we worked an example of solving an equation with pictures of square and rectangle shapes ("tiles").  Pairs of positive and negative tiles were erased to simplify the picture.  In our example, one rectangle (t) equals seven squares (7).

Today students presented their small dry-erase solutions to equations.
