Unpacked Content
Evidence Of Student Attainment:
Students:
  • Use strategies based on place value, properties of operations, and relationship between addition and subtraction to find sums and differences of decimals.
  • Use strategies based on place value, properties of operations, and relationship between multiplication and division to find products and quotients of decimals.
  • Use models to justify the sum, difference, product or quotient of decimals.
  • Solve real-world problems with decimals to hundredths.
Note: Products are limited to thousandths and quotients are either whole numbers or decimals terminating at the tenths or hundredths place.
Teacher Vocabulary:
  • Decimal
  • Tenths
  • Hundredths
  • Place value
Knowledge:
Students know:
  • Strategies based on place value understanding, properties, and relationship between operations to find the sum, difference, product, and quotient of whole numbers.
  • How to write decimal notation for fractions with denominators of 10 or 100.
  • Use estimation strategies to assess reasonableness of answers.
Skills:
Students are able to:
  • Use concrete models, drawings, and strategies to add, subtract, multiply, and divide decimals.
  • Relate strategies for operations with decimals to a written method and explain reasoning used.
  • Solve real-world context problems involving decimals.
Understanding:
Students understand that:
Problems involving operations with decimals
  • Can be solved using a variety of strategies based on place value, properties of operations, or the relationship between the operations.
  • Can be illustrated using concrete models or drawings.
Diverse Learning Needs:
Essential Skills:
Learning Objectives:
M.5.8.1: Use decimal notation for fractions with denominators 10 or 100.
M.5.8.2: Multiply and divide within 100, using strategies such as the relationship between multiplication and division or properties of operations.
M.5.8.3: Add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
M.5.8.4: Apply properties of operations as strategies to multiply and divide.
M.5.8.5: Identify that 100 can be thought of as a bundle of ten tens, called a "hundred".
M.5.8.6: Identify that the numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).
M.5.8.7: Recall basic addition, subtraction, multiplication, and division facts.

Prior Knowledge Skills:
  • Use fraction equivalence to add and subtract fractions and mixed numbers with unlike denominators.
  • Find whole number quotients and remainders using a variety of strategies based on place value and properties of operations.
  • Illustrate and explain the calculation using equations, arrays, and area models.
  • Use concrete models, drawings, and strategies to add, subtract, multiply, and divide decimals.
  • Relate strategies for operations with decimals to a written method and explain reasoning used.
  • Solve real-world context problems involving decimals.
Alabama Alternate Achievement Standards
AAS Standard:
M.AAS.5.8 Add decimals to tenths using concrete models, drawings, and manipulatives without regrouping.
Learning Objectives:

Students will be able to add, subtract, and multiply decimals to hundredths. 
  Strategies, Preparations and Variations  
Phase:
After/Explain/Elaborate
Activity:

Each student (or group of students) will need a die and a copy of the Decimal Menu page. Students will start by rolling the die to fill in each blank on the front of the menu.  They will also need to fill in the ingredients for the lunch meal (PB&J) and choose both the meal and the ingredients for the dinner section. 

After filling in the blanks, the students will calculate the total price for each meal by adding the decimal prices for each ingredient. They will need to remember to line up the decimals when adding -- you may want to have students use graph paper as a tool for keeping the place values lined up. 

The back of the menu has questions that require students to add, subtract, and multiply decimals based on the ingredients and prices from the menu.
Assessment Strategies:

The questions with the menu can be used as an assessment. Check the students' calculations to be sure they are performing the operations with decimals correctly.  
Advanced Preparation:

You will need dice for each student or group of students and a copy of the decimal menu sheet for each student (the activity can also be done in pairs or in groups). Students may benefit from using graph paper for working the problems.

Students will need to be familiar with adding, subtracting, and multiplying decimals for this activity.
Variation Tips (optional):

You can use any type of dice with single-digit numbers. If you don't have access to dice, students can use an online dice generator.
