A Math Interactive Notebook Is Similar to a Journal

TEACHER: Debbie Marks SUBJECT: 5th Grade Math

STANDARD:  5.NBT.7 - Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.

STUDENT TARGET:  I can add and subtract decimals  I can multiply and divide decimals.

EVIDENCE OF MASTERY (MEASURABLE):  SUB-OBJECTIVES, SWBAT  . KEY VOCABULARY: MATERIALS:  Sum, Product, Factor, Divisor, Quotient, Decimal  5th Grade Supply List  Sales Flyer  Individual White Boards & Markers  Projector **Paper & Colored Pencils for Math Interactive Notebook ENGAGE (MAKE CONTENT AND LEARNING RELEVANT TO REAL LIFE AND CONNECT TO STUDENT INTEREST) BEF TEACHER WILL:  STUDENT WILL: ORE  POSE THE FOLLOWING QUESTION: This morning, in the  DISCUSS: With their table group and McDonald’s drive-thru, I ordered a answer question.

Why or why not?

 ASK Students to share their answers. Why is it important to be able to add and subtract decimals correctly? What strategies can we use to add decimals?

POST: $ 6.35 +.15 $7.58  DISCUSS: teacher’s problem and come up with a rule designed to help correctly  ASK – is my answer correct? Why add or subtract decimals. or why not? Have students discuss at their tables and share-out answers.

 ASK: Students what strategies or rules are important to use when adding and subtracting decimals?

 EXPLAIN: That cashiers are not the only profession that needs to be able  BRAINSTORM – Jobs where it would to add and subtract decimals. be critical to correctly add/subtract multiply/divide decimals.  ASK: Students to brainstorm with their table. They will write down jobs where knowing how to add/subtract decimals would be important.

CO-TEACHING STRATEGY IF APPLICABLE

DUR TEACHER WILL STUDENT WILL: ING  INTRODUCE the challenge for the  WORK: With partner to complete the day. activity and answer questions.

Aidan went back-to-school shopping for classroom supplies. His mother gave him $25.00. She told him that the $25.00 had to cover ALL of the supplies on the 5th grade back-to-school list. Aidan really wanted to buy a Ninja Turtle backpack that cost $5.00. Can he purchase all the items on his back-to-school supply list and have enough leftover to buy the backpack?

Let’s go shopping! Use the back-to-school list and the sales flyer. Work with a partner. Make a list of everything purchased and its cost. How much wil he spend on the school supplies? Will he have enough leftover to buy his backpack?

Extension Question: While in line at the store, Aidan’s mom decided that she would cover ¼ of his total amount. How much did she pay for? Can he afford the backpack now?

CO-TEACHING STRATEGY IF APPLICABLE AFT  TEACHER WILL:  STUDENT WILL: ER  ASK: students to share their answers  SHARE answers and strategies and strategies for solving.

 HANDOUT – White paper. Ask  MAKE foldable and glue into Math students to cut out a square. Then to Interactive Notebook. fold each of the four corners into the middle of the square. On the top of each flap, students will write an operation in words and symbols both. (addition, subtraction, multiplication, division)

 INSTRUCT the students to write the rule for adding and subtracting under the appropriate flaps – then to create their own addition and subtraction problem and solve it.

 Students will then be asked to use the right side of their Math Interactive journal to write the day’s objective. Then glue their foldable with the addition/subtraction flaps filled out, underneath the objective. Students will finish the multiplication/division part of the foldable when covered in a separate lesson.

 HOMEWORK: Come up with a dinner menu to feed your family. Make a grocery list of items  DEVELOP a dinner menu for family, you will need to buy to cook dinner. make a grocery list and price each item Then either go online to find prices for on the list. Then student will determine the items, or go to the grocery store and how much their dinner will cost. record the prices for those items. How much will your dinner cost?
