1. Topic Of Lesson Plan

Computation and Estimation 


2. Lesson Content

To use shopping to practice estimation strategies and adding and
subtracting money.
Key vocabulary: estimation 


3. Goals And Expectations

1. Apply estimation strategies to situations using money/currency.
2. Students will understand the value of a dollar in a restaurant
and grocery setting.
3. Students will understand adding,subtracting and comparing two values
of currency. 


4. Objectives

PreCoversational/Beginning:
1.Students will be able to use mental math to add rounded sums of
money.
2.Work with a group to locate items from a sale circular and a menu,
estimating costs to the nearest dollar.
3.Correctly represent a math problem using the appropriate symbols
by recording it in their own math journal (5+5+10 > 10).
Intermediate:
In addition to above,
1. Students will estimate and determine which items cost less, as
well as understanding if eating the item at a restaurant is cheaper
than buying the items to prepare a meal at home when comparing.
2. Discuss the problem of comparison with a partner and recording
the process and explanation in their own math journal.
3. Explain in the Math Journal how Moosey (from the book) did not
save money after all.
Advanced:
In addition to above,
1. Independently write in math journals explaining the comparison/estimation
process.
2. Describe ways in which Moose could have saved money. 


5. Materials and Aids

1. Book "Moosey Saves Money" by Michael J. Pellowski
2. A sale flyer from a large grocery store like Wegmans
3. A Menu from a popular restaurant students will be familiar with
4. A food list with selected items (for example: 2 cucumbers, 1 gallon
of mlk, 1 onion).
5. Paper
6. Pencils
7. Calculator 


6. Methods Used and Procedures

A. Introduction
1.Introduce the book "Moosey Saves Money" by Michael J. Pellowski
to the class.
2. As students listen to the story, instruct them to use mental math
to determine if Moosey is saving money.
3. Introduce new concepts of spending and saving money.
4. Read the book to the class. 


B. Development
1. Discuss as a group whether or not Moosey saved money in the end.
2. Working in groups, but writing individually, have students record
their responses in their math journals.



C. Practice
1. Divide class into flexible groups. Distribute store flyers, and
restaurant menu to each group. Have groups recognize the best way
to save money by either choosing to go to the restaurant to eat, or
making their meal at home with purchased grocery items from the store.
2. Instruct students to determine if they can save money better than
Moosey did in the book. Students will be using estimation schools
to determine if eating out, or eating at home will be more or less
costly.
3. Still in groups, have students pretend they need to plan dinner
for a group of four. Provide a grocery list with prices for each item.
Dinner would include hamburgers, french fries, juice, and ice cream.
4. Predict what would be the best option when comparing these items
sold at the restaurant, and the prices given to purchase at the store.
Record predictions individually in journal after group collaboration.
5. After recording predictions, students will estimate to the nearest
dollar each item.
6. Students will then use a calculator to come up with a total amount
to compare the restaurant total, and the grocery list total. 


D. Independent Practice
1. Students will complete an assessment worksheet. (See worksheet.)
2. Student Math journal  open ended response
3. Instruct students to explain in writing what Moosey could have
done to save money. 


E. Accommodations For Students

F. Checking for understanding
1. 2. Openended option: Check students' math journals to determine
whether or not the predictions were correct. Check students' responses
as to whether or not Moosey saved money to evaluate their comprehension
of the story. (Moosey did not save money. He spent 30 dollars in medical
bills plus ten dollars to fix the faucet instead of spending the original
ten dollars to fix the faucet).
2. Students will show understanding with their ability to answer the
multiple choice questions on the worksheet correctly, showing work
and estimation to the nearest dollar.
3. Students will show understanding by full expression and comprehension
of the story and activity completed in class. 


G. Closure
Discussion some of the estimations and how accurate they were. 


7. Evaluation

1. Complete homework sheet on estimation.
2. Unit test.
