Unit 10 Using Data: Algebra Concepts and SkillsMessiah College

Instructional Plan Template forElementary, Early Childhood, and Secondary Education

Name: Jenna Max Subject: MathematicsDate: April 2010 Topic: Using Data; Algebra Concepts and Skills

Grade: 5 School: Middle Paxton Elementary

A. Instructional Goal and Learning Outcome Learners will be able to solve equations using a pan-balance model.Learners will be able to represent relationships as algebraic expressions.Learners will be able to generate input-output tables.Learners will be able to link data in tables to corresponding points on coordinate (rules and principles)

UEQ: Why is it important to understand algebraic relationships? How do we use algebra in our everyday lives?How would you use number sentences with variables to represent relationships?How are circumference and diameter related?

B. Pennsylvania Academic Standards

Standard 2.5.5.B: Use appropriate mathematical terms, vocabulary, language, symbols, and graphs to explain clearly and logically solutions to problems

Standard 2.8.5.B: Select and use strategies, including concrete objects, to solve number sentences (equations and inequalities) and explain the method of solution.

Standard 2.8.5.C: Recognize, describe, extend, create, replicate, and form a rule for a variety of patterns, sequences, and relationships verbally, numerically, symbolically, and graphically.

Standard 2.8.5.D: Determine a functional rule from a table or graph.

Standard 2.8.5.E: Use concrete objects and combinations of symbols and numbers to create

expressions, equations, and inequalities that model mathematical situations.

Standard 2.8.5.F: Describe data represented in equations, inequalities, tables, or graphs and/or create a story that matches that data.

C. Essential Content

-Pan-balance Equation: a method for seeing value of numbers and unknowns—used as a metaphor instead of an actual measurement tool—we can use the pan-balance to find the value of

Page 2: Messiah College - Central Dauphin School District · Web viewHave students follow along—use gradual release model---we (as a class) will do question 7—then students will try questions

objects that are unknown by seeing what objects have the same “weight” (see lesson 1 and attached SMARTboard for more detail)-Algebraic Expression: A number sentence with variables, or unknowns, that must be found by working with the remainder of the equation to solve for the variable ex: 5y +5=30 –we want to get y by itself and find its value, so we must subtract 5 from both sides to get: 5y=30. Then we must do another step and divide both sides by 5—we then get y=5. (note that to take a number away from the equation, you must do the opposite function to both sides of the equation). -Tables: used for data entry Ex:

-Graphs: used for plotting data

-Circumference: C=d x п-Diameter: the distance across a circle-Radius: the length from the side of a circle to its midpoint-Pi: the 16th letter of the Greek alphabet; 3.14159265358979323846...-Area of a circle: A=п r²

D. Instructional Objective (description of Summative Assessment Strategy)

Context / Given Students will be given an assessment packet (pg 200-204) in

Assessment Handbook) containing problems involving fractions and ratios.

Performance / Behavior

Capability : Learners will able to demonstrate their knowledge of rules and principles for solving problems including algebraic equations, pan balance problems, interpreting graphs and tables, finding circumference, finding diameter, and finding radius of a circle by correctly solving provided questions.

Specific Action : Students will solve given problems that require the use and formulation of algebraic equations, use of pan balance, interpretation of graphs and tables, finding circumference, finding diameter, and finding radius of a circle by correctly solving provided questions.

Quality Students must score a percentage of 80% or above on the

written assessment to demonstrate mastery.

E. Instructional Sequence

1. Pre-instructional Phase (preparation)

To prepare for each lesson, I will start by having student review the content covered from the previous day.

time

-For the very first lesson (10-1), we will review key vocabulary to activate and build on students’ prior knowledge and will start to get their minds thinking towards the new topic being addressed.

-Following the introduction lesson for the unit, the review for each lesson will either be in the form of reviewing the previous day’s work, reviewing important vocabulary, or reviewing practice problems together as a class.

-This will take on multiple forms:-trading and grading workbook pages-whole-class participation in executing practice problems (through mental math

reflexes)-Think-pair-share rules or skills used from the previous day’s lesson-Mini-review lesson (if topic proved to be difficult for many students)

2. Instructional Phase (engagement)

For each daily lesson, I will engage the class by explaining the essential content for the day.

-This will take multiple forms:-verbally teaching the essential content with supplements on the SMARTboard-modeling certain skills, processes, and problem solving on the overhead or

whiteboard-walking students through practice work book pages by modeling the processes

required to find solutions-using manipulatives to give students a visual and tactile experience to solidify

concepts being taught

3. Post-instructional Phase (strengthening/practice) & Extending and Refining

For each daily lesson, I will provide strengthening activities through practice book pages as well as supplemental practice games for students to engage in to develop competency, fluency, and confidence in the skills and content being taught.

-Practice pages will be from the Student Reference book, Math Journal, and the Math Masters student practice books.

-Games and supplemental activities will be provided from online sources or from the Math Masters student book.

F. Summative Assessment (Consistent with Instructional Objective)

Using the Assessment Handbook, students will complete the written assessment: pages 200-204 (page 204 will be given as a bonus activity because of its difficulty). Students must score an 80% or above to demonstrate mastery.

G. Modifications and Accommodations

Page 4: Messiah College - Central Dauphin School District · Web viewHave students follow along—use gradual release model---we (as a class) will do question 7—then students will try questions

-Students with IEP’s may be given additional instruction during group extension activities. During extension games or independent seatwork, students will be given additional explanations, examples, and modeled practice if needed.

-Groups may need to be selected for students (because of attention problems). Certain students will need to be paired or grouped strategically so that they will be on task and more responsible in their role in the group work/activity.

-Students who have difficulty seeing the board may come to the front of the class and sit with a clipboard for the lesson.

-For students with IEP’s or for students who may have trouble keeping up with the work or practice, I will cluster their assignments on each worksheet. I will have them complete one cluster at a time so that they will not be overwhelmed with the amount of work they will need to do. This will also help them stay focused and meet little goals that will build up to reaching bigger goals. (This will be utilized and attempted to be slowly taken away to foster independence)

-Additionally, I will provide time before school and during recess for students to come to me for additional one-on-one instruction for difficult content. -I will have my SMARTboard lessons online for resources for students to access at home for additional practice and guidance.

Mental Math pg. 798 –Around the World—3 row styleMath Message: Create a table for height—See SMARTboard and pg. 798

Specific Learning Activities and Instruction LEQ: How do I write algebraic expressions to represent situations and describe

rules?

Teach/Review: Review Math Message: emphasize how Joe’s height depends on Maria’s height (relate

this to pan balance—how one value affects the other) Discuss “what’s my rule” tables and show how these tables represent algebraic

expressions Review definitions and elements of algebraic expressions on pg. 218 of SRB Have students create an algebraic expression for the Math Message Example:

o M=Maria’s height J=Joe’s heighto M+2=J or J-2=M

Reinforce: expressions use operations symbols (+ - * ÷) to combine numbers, algebraic expressions combine variables and numbers

Note: a situation can often be represented in several ways: words, in a table, or in symbols

Tell: Algebraic expressions use variables and other symbols to represent situations

*Model sample algebraic expressions on SMARTboard from TE 799***

Teach/Review: Review #1 on MJ 354—discuss plotting points and have students make predictions (will

the line graph increase or decrease?) Discuss how even though this table looks different from a “what’s my rule” table, it still

has a rule The rule describes the relationship between the coordinates of the ordered number

pairs Model: writing the algebraic expression of the relationship between the x and y

coordinates (Ex: y= 5-x or x=5-y) Write each equation for each ordered number pair on the board and have students label

their graph with the equations Show students that extending the line with the straightedge, we see more points that

follow the same rule (challenge: have them check with fractions and negative numbers)

square is comparable to the circumference of a circle Draw example on the SMARTboard comparing perimeter and circumference

Specific Learning Activities and InstructionLEQ: What is the circumference of a circle? How do I find the circumference of a circle and how can I use a formula to find this value?

Teach/Review: Review how to find the perimeter of a rectangle: P=s+s+s+s Demonstrate how the relationship between perimeter and the side value can be expressed

as a ratio---this comparison is called a ratio comparison Demonstrate (on SMARTboard) that a radius is the distance from the outside of the circle

to the center—and is comparable to the side of a rectangle Research: Have students find the definition of diameter, radius, and circumference in

their SRB glossary (read definitions aloud and use SMARTboard diagram for visual aid) Make the connection that Circumference is the value of the outside of the circle, just as

perimeter is the value of the outside border of the rectangle Highlight that finding the circumference requires a different formula:

o C=п x d or C= п x r²o Define Pi: the number expressed by a letter in the Greek alphabet to

represent the value of the ratio between circumference and diameter (3.14….)

o Note: pi is an irrational number and continues infinitely without a discernable pattern—so we round and use an approximation or ≈ (approximately equal to)

o Calculator search: have students find pi on their calculators
