About this worksheet: This worksheet is meant to allow the teacher to grade for correct answers quickly and accurately without grading every single problem by hand. You should tell the students that the dots will not form a picture like they are used to. You can tell them that if they do it correctly then a regular hexagon can be found somewhere on the page (it is not necessary to tell them though), but it may not be made with the dots on the paper. The hexagon is for you to help identify whether or not students did the bulk of the worksheet correctly. Note that the regular hexagon is formed by making straight line segments from point to point, so the students do need to use a straightedge when connecting the dots.
Interpret the structure of expressions.
Interpret expressions that represent a quantity in terms of its context.*
Interpret parts of an expression, such as terms, factors, and coefficients.
Use the structure of an expression to identify ways to rewrite it. For example, see x4 - y4 as (x2)2 - (y2)2, thus recognizing it as a difference of squares that can be factored as (x2 - y2)(x2 + y2).
Write expressions in equivalent forms to solve problems.
Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.*
Factor a quadratic expression to reveal the zeros of the function it defines.
