Developed as part of the Math Circles of Inquiry project, this five to six day activity is designed to help students understand trigonometric ratios, by building on their understanding of similar triangles and ratios of corresponding sides.
Mary Plumb
This session is for students familiar with linear equations, primarily late 8th grade, Algebra I/II and Geometry students. Student work starts with a very simple and concrete example of a linear relationship word problem which is then used to explore four forms of linear equations. The purpose of the activity is to increase student familiarity and efficiency working with different forms of linear equations, particularly how an equation's structure can provide slope and point information without algebraic manipulation.
