The agenda for Monday, September 14th includes completing a self-assessment of a glyph, learning about variables and patterns by making a coordinate graph, and homework on variables and patterns problems. The document provides instructions on how to make a coordinate graph by identifying variables, selecting axes to represent each variable with one on the x-axis and one on the y-axis, selecting an appropriate scale for each axis, plotting coordinate pairs, and labeling the graph. Students are asked to complete a coordinate graph activity with a partner and answer summarizing questions. Homework assigned is variables and patterns problems 1-3 using graph paper.
