Phase: | After/Explain/Elaborate |
Activity: | 1. The teacher will provide the students with a list of functions to pick from or assign specific functions. (The functions can include radical, quadratic, absolute value, reciprocal, and trigonometric functions.) 2. The students will graph their functions and label key features. 3. Students can use www.desmos.com or a graphing calculator to check graphs before drawing them on the large graph paper. If the teacher does not have large graph paper then the students can use individual graph boards and will not need desmos.com.
|
Assessment Strategies: | Students will demonstrate their ability to graph functions and label key features on those graphs by graphing the given functions. The teacher will determine if the student has successfully displayed their ability to graph functions and reteach in small groups as needed.
|
Advanced Preparation: | The teacher will create a list of functions to have the students graph in a group. The teacher will need poster-sized graph paper. They will also need a set of graphing calculators or computers/Chromebooks if using the digital tool. The students will need yardsticks and markers for the poster-sized graph paper. (If the teacher does not have the poster-sized graph paper, individual graph boards can be used to assess understanding.) The groups of two to four students would be appropriate for this activity. The teacher can use a deck of cards to randomly assign members to the groups or the members can be assigned to the groups by ability. |
Variation Tips (optional): | If the teacher does not have the poster-sized graph paper, the students can do the graph on individual graph boards. If students need remediation the teacher can use small group instruction time to help the students. |
Notes or Recommendations (optional): | ALCOS 2019 20. Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases. Extend to polynomial, trigonometric (sine and cosine), logarithmic, reciprocal, radical, and general piecewise |
