RECOMMENDED INSTRUCTIONAL DESIGN AND PLANNING CONTINUUM Before Prior to the lesson: Outline content standard(s). Determine learning targets. Anticipate student understanding and misconceptions. Determine prerequisite skills. Plan for learning experiences that target Rigor o Conceptual Understanding o Procedural Fluency o Application Determine the task students will demonstrate to reach the desired learning targets. Plan instructional delivery methods that will maximize initial engagement and sustain it throughout the lesson. Decide how students will reflect upon, selfassess, and set goals for their future learning. During the lesson: Activate (or supply) prior knowledge and/or spiral back o Warm ups, Bell Ringers, Openers, etc. Tailor lesson experiences to the different needs and ability of the learners. Clarify vocabulary and mathematical notation. Incorporate a variety of higher order questions to encourage and increase critical thinking skills. Continuously check for student understanding and provide feedback. Provide opportunities for students to develop self-assessment and to reflect about their understanding and work. Bring closure to the lesson so that the students can articulate what they have learned. After the lesson: Analyze evidence of student learning to develop intervention, enrichment, and future instruction. Discuss results of assessments with students. Engage students in reflective processes and goal setting. Engage in self-reflection to adapt/modify teaching strategies to improve instruction.

Vocabulary

Mathematically Speaking! Choose 3 -4 vocabulary words for the day. Throughout the lesson, as students respond to your questions or are presenting a problem on the board, mark a tally when a vocabulary word is used accurately. This can be turned into a competition among groups or between periods. Examples of accuracy • translation vs slide • variable vs letter • addition property of equality vs adding on both sides

Relations A set of ordered pairs.

Domain The set of input values of a function or relation.

Range The set of input values of a function or relation.

Function A relationship between two quantities in which every input corresponds to exactly one output. A relation is a function if and only if each element in the domain is paired with a unique element of the range.

Function - Representations

Function Rule An algebraic expression that defines a function. •

Discrete Graph A graph made up of unconnected points.

Continuous Graph A graph made up of connected lines or curves.

Independent Variable •

Dependent Variable •

Dependent and Independent Variable Determine the distance a car will travel going 55 mph.

Arithmetic Sequence A sequence whose successive terms differ by the same nonzero number called the common difference.

Operations on Functions Operations on functions are similar to operations on numbers. Each operation has a formal definition which produces a new function.

• Composition of Functions

MAFS. 912. F-BF. 1. 1 a & MAFS. 912. F-IF. 2. 5 A summer camp wants to take a field trip to the water park. They are taking a school bus that can hold 42 students. It will cost $25 to park the bus. Tickets to the water park are $18. 50 person. a) Write a function that models the total cost for the summer camp to go the water park. a) Identify and explain the domain for this scenario. The problem says that the bus can only hold 42 people, so I know that my domain has to be less than or equal to 42. However, since negative numbers are also less than 42 and I can’t have negative people. I have to have a lower limit on my domain of 0. Therefore, my domain is only integers {0 < n ≤ 42 } if only one bus is requested. Students might identify that if no one signs up there will be no trip. They may also recognize that if more than 42 students want to come, they could request another bus.
