Notes:

 

 

Stage 1: Identify Desired Results

 

State:

KS  

Title:

Math Standard 3 Benchmark 2, Indicator 1

Standard(s):

Standard 3: Geometry

Benchmark 2: Measurement and estimation: the student estimates and measures using standard and nonstandard units in a variety of situations.

Indicator 1: The student formulates and solves real-world problems by applying measurement and measurement formulas. For the purposes of assessing this indicator on the Kansas Assessment the student should be able to work with the following measurements and conversions:

a)        Area of rectangles and squares.

b)        Perimeter

c)        Length

d)        Conversions within the same measurement system

 

Understandings:

Overarching

Measurement helps describe and understand the world.

 

Unit

Measuring is a common, everyday practice

Area and perimeter measure different aspects of the same shape.

We can convert from one measurement unit to another within the same measuring system.

 

Essential Questions:

Why do we measure?

How do we measure?

What are some formulas to help us measure area and perimeter?

How do we convert units of measurements within the same measurement system?

 

Knowledge and Skills:

K

·          perimeter measurement formula .

·          an area measurement formula.

·          Conversion  measurements within the same measurement system: Standard measurement (inches to feet, inches to yards, and feet to yards; Metric measurement: (centimeters to meters)

S

·          The student will apply a perimeter measurement formula to solve a real world problem.

·          The student will apply an area measurement formula to solve a real world problem.

·          The student will convert measurements within the same measurement system:  Standard measurement (inches to feet, inches to yards, and feet to yards; Metric measurement: (centimeters to meters)

 

Stage 2: Determine Acceptable Evidence

 

Assessment Summary:
Students apply perimeter, area, and measurement conversion formulas to find out how much fencing and brick tile will be needed to a fenced-in area in the school courtyard.

 

Student Directions:

 Courtyard Proposal

 

                Cheney Grade School is building a small fenced-in bricked area to place a bird feeder and birdbath in our courtyard. Mr. Becker, our principal, and Student Council have asked you to be in charge of determining the amount of materials the school needs to buy.

 

Our Student Council and Mr. Becker decided that this area:

·          Would measure 6 feet by 9 feet.

·          Would have a fence around the outside perimeter.

·           The fencing must be bought by the yard.

·          The brick tile each would be 1 square foot.

 

Your job is to design a proposal that shows and explains:

·          The number of yards of fencing that will be needed.

·          The number of bricks that will be needed.

 

Please show and explain how you solved and calculated the amount of materials requested in your proposal. Mr. Becker and Student Council need to be sure your proposal is accurate.

Other assessment evidence to be collected:

Area

·          1. (Concept of area) -Make polygons with one foot square newspaper squares using teacher directed area number. Write their definition of area.

·          2. (Application of area formula to rectangles) – “The Wizard’s New Bricks”

 

Perimeter

·          3. (Concept of perimeter) – Write their definition of perimeter.

·          4. (Application of perimeter formula to rectangles) – Students will write a “look –alike” story using information from bulletin board activity.

·          5. (Application of perimeter formula to polygons) – Follow-up to monthly calendar activity.

 

Perimeter & Area

·          6. (Application of both perimeter and area formulas) – “Toto’s Crate”

 

Conversions

·          7. (Conversions of standard units of measurement) – Use 10-12 student and teacher written conversion stories.  Use stories from www.ksbe.state.ks.us .

a.        Ben has 3 yards of ribbon and 8 balloons. Each balloon needs an 18-inch ribbon tied to it. How much more ribbon does he need? (a) 1 yard (b) 2 yards (c) 3 yards (d) 4 yards.

 

·          Combination stories (use perimeter, area, conversion of measurement)

8. Performance assessment – Courtyard Proposal

 

 

Stage 3: Plan Learning Experiences and Instruction

 

Learning Activities:

 Pose situation about finding area (how much paper to cover) and perimeter (how much border needed) of classroom bulletin board.

 Students will experience hands-on experiments to develop the concepts of area and perimeter.  They will then apply area and perimeter formulas to story problems. Students will also convert measurements within the same measurement system for standard measurement (inches to feet, inches to yards, and feet to yards).

 These activities are designed for a daily 10-15 minutes time frame. This is to supplement our district’s core Math curriculum. Each bullet is a day’s lesson.

 

Area: (Concept )

·          Make square feet from newspapers

·          Experiment with polygons using newspaper square feet

·          Record different shapes and areas on graph paper

·          Experiment with rectangles using newspaper square feet

·          Record different rectangles and area on graph paper (discuss rectangle area formula: length x width  = area).

·          ASSESSMENT #1

 

 

 Area: (Application of area formula)

·          Prompt:  Nellie wants to carpet her doghouse. It measures 3 feet by 4 feet. How much carpet will she need? Find answer & discuss story parts.

·          Students write look-alike stories with a partner. Then they will find the answer and do model on graph paper.

·          Students will help design checklist or rubric to use for grading.

·          Students trade with another group. They work the other group’s story.

·          Students check their story papers with checklist or rubric. Discuss with other group.

·          Each partnership will make a poster with story, answer and illustration.

·          ASSESSMENT #2

 

 Perimeter (Concept)

·          Measure desks, use yarn to prove perimeter measurement  (www.teacher.net.lessons/ posts/2186.html)

·          Draw imaginary dog pen that needs to be build (20 feet) on board. Measure and mark on tennis court to show actual size. (www.teacher.net.lessons/ posts/2186.html)

·          Make polygons out of newspaper square foot squares. Count outside edges to find perimeter measurement.

·          Make newspaper polygons again. This time record and label on graph paper.

·          ASSESSMENT  #3

 

 Perimeter: (Application of area formula)

·          Measure classroom bulletin board to figure how much border it would need. Write as story.

·          Students write look-alike stories with a partner. Then they will find the answer and do model on graph paper.

·          Students will help design checklist or rubric to use for grading.

·          Students trade with another group. They work the other group’s story.

·          Students check their story papers with checklist or rubric. Discuss with other group.

·          ASSESSMENT #4

·          Monthly calendar activities – Each day students with figure perimeter of polygon.

·          ASSESSMENT #5

 

 Perimeter & Area

·          Bulletin board – review perimeter – find out how much paper would be needed to fill the bulletin board.

·          ASSESSMENT #6

 

 Conversions

·          Measure height of group in inches. Convert to feet and inches.

·          Smile style – Measure group’s smiles in inches, add up in inches, and convert to measurement from inches to feet. Combine class smile measurements, add up in inches, and convert to both feet and yards.

      (Adapted from http://mathforum.org/paths/measurement/smile.html)

·          Do Activity #1 using other body parts: feet, arms, heads, etc. Measure in inches and then convert.

·          Measure Fine Arts Center or tennis court in yards. Convert to feet and inches.

·          Measurement Conversions game – a board game with various units of measurement that student convert from one unit to another (example:  15 inches = ___ ft & ___in). (adapted from http://mathforum.org/paths/measurement/meticconv.html).

·          Students design stories where standard unit conversions are needed. Example: Mary is 5 feet tall. Joe is 58 inches tall. Stan is   yards tall. Who is the shortest? (www.ksbe.state.ks.us).  Solve their own and others.

·          ASSESSMENT #7

 

 

 Combination stories (use perimeter, area, conversion of measurement)

·          Use stories from www.ksbe.state.ks.us. Make look-alike stories
