UNIT 4: EXPRESSIONS AND EQUATIONS
Section 4.1: Polynomial Operations and Modeling
Standards Addressed: A.SSE.1, A.APR.1, A.CED.1, A.CED.2
4.1A: I can add and subtract polynomials.
4.1B: I can multiply polynomials.
4.1C: I can create equations to model situations and use them to solve problems in the context of the situation.
Section 4.2: Zeros of Quadratics Algebraically
Standards Addressed: A.SSE.2, A.SSE.3, A.CED.4, A.REI.4, A.REI.7
4.2A: I can find zeros of quadratic functions by taking the square root.
4.2B: I can find zeros of quadratic functions by factoring.
4.2C: I can find zeros of quadratic functions by completing the square.
4.2D: I can find zeros of quadratic functions by using the quadratic formula.
4.2E: I can solve an equation/formula for a specified variable.
- Do I really need 4.2A? I'm looking at A.REI.4b, which says students solve by inspection, taking square roots, completing the square, the quadratic formula, and factoring. Well, that's a lot, so I feel like it needs more than one LT, but not 5! And to me if you solve by CTS you are taking a square root...would basic square root equations build up to CTS? I would prefer 4 LTs to 5 in that section...thoughts?
- I'm a little confused about how I can fully meet A.SSE.3 and A.CED.2 which both have graphing components when most of the graphing standards aren't until Unit 5 (F.IF.7, F.BF.3, and many others). We will likely do all our graphs by plotting points or using technology for Unit 4.
- Last year when we found zeros of quadratic functions we did algebraically, numerically, and graphically all together. I'm a little sad that they are split up here. :( I like drawing all the connections, but it will have to wait to Unit 5.
Please give feedback by commenting below or tweeting me (@kathrynfreed). I really appreciate how much everyone has helped me so far with processing these. Every time I think my brain is over-capacity with thoughts on standards and learning targets somebody will make a comment that gets me thinking again!
For those of you who have been walking through this entire journey with me, there is only one unit left! Hang in there!
