Experiment with cases and illustrate an explanation of the effects on the graph using technology. MA.912.A.7.1 Graph quadratic equations with and without graphing technology. Engage Students will be asked to pass forward homework and clear their desks for the test. Engage Students will play an online game where they must determine the pattern in the numbers L A complete the square to write equations in vertex form, so this will be their preparation. Engage also includes answering questions from the previous night’s homework. 10 minutes from parent graphs. They will use similar skills to transform quadratics today so this review will remind them how to approach these problems. Engage also includes answering questions from the previous night’s homework. 10 minutes whole class period, so there is no engaging activity/bell ringer. The engage will include answering questions from homework though which will take up to 10 minutes. 10 minutes Explore Students will explore completing the square to write equations in vertex form. They will be given a worksheet that guides their thinking towards why equations should be written this way for graphing. This will lead into Tuesday’s graphing and transforming quadratic equations in vertex form. The worksheet will also prompt students to make connections regarding the vertex, axis of symmetry, and direction of opening with and without the graph. At this time the teacher will circulate to ask questions, answer questions, and encourage students to apply their prior knowledge about completing the square and transformations to answer the questions. 15 minutes Explore Students will explore transforming quadratics with a Formative Assessment activity where they must choose the odd one out. Students will receive a worksheet to work alone so that they must write out sentences in their own words. This way the teacher can analyze individual student progress and level of understanding. Students are held accountable for this work because they will be informed that this will be collected and graded for correctness (instead of the usual completion grade). The odd one out worksheet challenges students to find which of the quadratic equations in vertex form is different from the others. Some are more obvious than others, but without graphing students may find this quite challenging. (Students who wish to graph each one will be allowed to do so.) The worksheet requires students to explain their answers. This will give the teacher the Explore Students will work on a worksheet that is really just blank lines with instructions for writing. Students will review the material themselves and essentially write down what they find to be the most important take-aways from each section. They will then share this with a partner and try to convince him/her that their own choice is the most significant. The students will be asked to review and work alone for 20 minutes before getting with a partner. 20 minutes Explain Once with a partner, students will debate and learn from one another other important material they may have missed and further study the points they may have agreed on to be the most significant. This activity requires students to use words instead of just formulas to describe math problems and situations. This will Explain Students will be called on to provide answers and explanations for the worksheet problems. At this time the teacher will given the input and the output. This is a fun way to disguise preparing to write a function given a table a values. This skill has not been used recently, but appears on the worksheet, so a review will prepare the students for one of the questions. http://pbskids.org/cyberch ase/math-games/stopcreature/ 8 minutes Explore Students will not explore today but have a test on material from sections 5.4 – 5.7. Complex and imaginary numbers, completing the square, the quadratic formula and Discriminant, and transformations. Explain No explain today – students will have a test. Elaborate No elaboration today – students will have a test. Students who finish early will be asked to preview next chapter’s material and sit quietly. They will be rewarded with Halloween candy for taking notes on the next chapter. Explore Students will be given a color by number worksheet with a Halloween image. The numbers to color are 1-9. Students will solve and simplify various problems they have practiced throughout the quarter. This will also serve as a review and allow students to check themselves if they get a number not 1-9. This also allows the teacher to circulate and monitor which type of problem students still struggle with. 27 minutes Explain Students will be called on to work each problem from the worksheet on the board while taking hints from classmates. This will give the teacher to watch first hand how students are solving and how classmates suggest to other students how they solved it similarly or perhaps differently. 10 minutes instruct students to make notes and highlights on their individual paper. They will then be instructed to take notes on the PowerPoint. The PowerPoint will be projected for students to have in writing what they just explored. This includes step by step how to convert equations to vertex form, and how to interpret aspects of the graph. 20 minutes Elaborate Students will be given a problem and asked to convert an equation in vertex form back to standard form. This will review foil method and help students see how the same equation can be written in different ways and how certain forms are better depending on what the goal of the problem is. 5 minutes N Evaluate and Summary Homework will be assigned from the Workbook 5.7 Skills Practice #1-9. This will be checked Tuesday. opportunity to see how proficient students are based on their ability to convey their thoughts in sentence form. 15 minutes Explain Students will volunteer themselves to share their answers from the worksheet. (Students who would like to eat candy will share their answers). The concept of transformations will be explained further with a PowerPoint using graphs for students to visualize. This will help students connect the vertex forms on their papers to graphs. They will be instructed to make notes on how each letter in the vertex form transforms the graph. 20 minutes challenge students to analyze what they have learned on a deeper level than just recalling facts and algorithms for problem solving. This will also allow the teacher to walk around and listen to the talking and level of understanding of the material. This will be collected for a grade so the teacher can view each student’s thoughts on paper and compare it to test scores. 20 minutes Elaborate Students will be given a second worksheet to color by number. The problems will test the same type of review material. 5 minutes Elaborate No elaboration. Students will be asked to change partners if time remains after debating with original partner. Elaborate Students will combine their knowledge from Monday and Tuesday to graph, and write out the transformations for a quadratic equation. However this equation will be in vertex form and they must first convert it without being instructed or reminded to do so. 5 minutes Evaluate and Summary Homework will be assigned from Workbook 5.7 Skills Practice #10-15. Evaluate and Summary A practice test will be given for homework. Evaluate and Summary Student achievement and mastery of concepts from 5.4 – 5.7 will be assessed through a test. The test covers Complex and imaginary numbers, completing the square, the quadratic formula and Discriminant, and Evaluate and Summary transformations.
