We mapped out the Cartesian coordinate (XY) system, with x and y axes, origin, quadrants and ordered pairs on the white board and on graph paper.

I gave Cal a test on punctuation and grammar and then thoroughly reviewed the test.

We reviewed constants, variables, terms, like (similar) terms and algebraic expressions. Then we worked several examples of simplifying algebraic expressions, leading us into a brief explanation of the distributive property and several examples on the board.

We reviewed many of the various punctuation and grammar rules, with which Cal did well. We then worked on his personal, five-paragraph essay.

We worked through several problems, by hand and on the graphing calculator in which we dealt with calculations involving multiple exponents.

We reviewed yet again the basic components of a five-paragraph, persuasive essay. Cal's work from the previous week was barely a scratch of the surface with regard to what we've been doing so we went back to square one: how to write an introduction.

We continued to review the mechanics of the five-paragraph essay as wall the grammar and punctuation rules that we have worked on from the beginning.

Cal called in at the last minute saying he was vomiting and could not make it to the session.

We defined the word "matrix," showed some real-life examples and worked a few problems of matrix addition, matrix subtraction, and scalar multiplication of matrices. We also used the graphing calculator to work the same operations.
