STAGE 1: IDENTIFY DESIRED RESULTS

Content Standard(s)

Generalizations about what students should know and be able to do

Established Goals:

 

CT Framework:

a)     Properties of numbers are used to develop strategies for computation and estimation.

b)     Percents can be used to make comparisons between groups of unequal size because each group is based on a ratio of parts per hundred.

NCTM Standards:

a)     Understand numbers, ways of representing numbers and relationships among numbers.

b)     Understand the meanings of operations and how they relate to one another.

c)     Compute fluently and make reasonable estimates.

 

Enduring Understandings

Insights earned from exploring generalizations via the essential questions (Students will understand THAT…)

Essential Questions

Inquiry used to explore generalizations

The student will understand that:

  1. whole numbers, fractions, and decimals

can be read, written, and rounded..

  1. whole numbers, fractions, and decimals

can be added, subtracted, multiplied,

and divided..

  1. there are divisibility rules.
  2. there are prime and composite numbers.
  3. relationships between fractions exist
  4. operations with whole numbers,

fractions and decimals can be used to

solve word problems.

  1. percents are a ratio.

 

      

 

  1. What are the ways whole numbers, fractions, and decimals  can be read, written, and rounded?
  2. How are whole numbers, fractions, and decimals added, subtracted, multiplied, and divided?
  3. What are the divisibility rules?
  4. What is a prime number and what is a composite number?
  5. What relationships exist between fractions?

2.      Given problems with whole numbers, fractions, and decimals, students will add, subtract, multiply, and divide.

3.      Using the two rule, three rule, five rule, and ten rule for divisibility, students will tell whether a number is divisible by 2,3,5,or 10.

4.      identify a number as prime or composite.

5.      set up and do problems using ratios and proportions.

6.      set up and solve word problems by adding, subtracting, multiplying, and dividing whole numbers, fractions, and decimals.

7.      set up and find the missing  rate, percentage, or base for a percent problem.

STAGE 2: DETERMINE ACCEPTABLE EVIDENCE

Performance Task(s)

Authentic application in new context to evaluate student achievement of desired results designed according to GRASPS (Goal, Role, Audience, Setting Performance, Standards)

Other Evidence

Application that is functional in a classroom context only to evaluate student achievement of desired results

Suzanne goes to the local department store and wants to buy a dress for homecoming.  She finds a dress that sells for $125.00 on a rack that has a 25% off sign on it.  Two racks down she finds a dress that sells for $115 and is 15% off.  To make matters worse, Suzanne has only $94.00 to spend on this dress.  Determine the actual cost of each dress.  Which dress can Suzanne afford and why?

 

In addition to quizzes and/or tests, one or more of the following will be used:

  1. cooperative learning
  2. scientific calculator activities
  3. informal and formal checks:

homework checks, problem of the day

and review sheets.

STAGE 3: DEVELOP LEARNING PLAN

Learning Activities:

1.     cooperative learning activities

2.     scientific calculator activities

3.     homework and review worksheets.
