Enduring Skills Rubric measures competency of the following skills: Essential Question(s) Adds, subtracts, multiplies, or divides decimals to hundredths, accurately using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction Fluently multiply and divide by 10 and powers of 10 Explains patterns in the number of zeros of the product when multiplying a number by powers of 10 and placement of the decimal point when a decimal is multiplied or divided by a power of 10; uses whole number exponents to denote powers of 10 Constructs and communicates a well-organized and complete written response using a logical progression of steps How do we solve problems with decimal numbers? What questions will provoke and sustain student engagement while focusing learning? Standards Standards for Mathematical Practice 1. Make sense of problems and persevere in solving them. Students solve problems by applying and extending their understanding of addition and subtraction to decimals. Students seek the meaning of a problem and look for efficient ways to solve it. They determine situations when decimal numbers should be rounded and when they need to be exact. 2. Reason abstractly and quantitatively. Students demonstrate abstract reasoning to connect decimal quantities to fractions, and to compare relative values of decimal numbers. Students round decimal numbers using place value concepts. 3. Construct viable arguments and critique the reasoning of others. Students construct arguments using concrete referents, such as 1 MADISON COUNTY PUBLIC SCHOOLS District Curriculum Map for Mathematics: Grade 5 Unit 3 4. 5. 6. 7. 8. objects, pictures, and drawings. They explain calculations with decimals based upon models and rules that generate patterns. They explain their thinking to others and respond to others’ thinking. Model with mathematics. Students use base ten blocks, drawings, number lines, and equations to represent decimal place value, addition, and subtraction. They determine which models are most efficient for solving problems. Use appropriate tools strategically. Students select and use tools such as graph paper, base ten blocks, and number lines to accurately solve problems with decimals. Attend to precision. Students use clear and precise language, (math talk) in their discussions with others and in their own reasoning. Students use appropriate terminology when referring to decimal place value and use decimal points correctly Look for and make use of structure. Students use properties of operations as strategies to add and subtract with decimals. Students utilize patterns in place value and powers of ten and relate them to rules and graphical representations. Students also use structure to read, write, and compare decimals. Look for and express regularity in repeated reasoning. Students use repeated reasoning to understand algorithms and make generalizations about patterns. Students connect place value and properties of operations to fluently add and subtract decimals. Standards for Mathematical Content 5.NBT.2 Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10. 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. Supporting 5.NBT.1 Recognize that in a multi-digit number, a digit in one place Standard(s) represents 10 times as much as it represents in the place to its right and Which related 1/10 of what it represents in the place to its left. standards will be incorporated to support and enhance 5.NBT.3 Read, write, and compare decimals to thousandths. a. Read and write decimals to thousandths using base-ten numerals, number names, and expanded form, e.g., 347.392 = 3 × 100 + 4 × 10 + 7 × 2 MADISON COUNTY PUBLIC SCHOOLS District Curriculum Map for Mathematics: Grade 5 Unit 3 the enduring standards? Instruction al Outcomes What must students learn and be able to by the end of the unit to demonstrate mastery? Vocabular y What vocabulary must students know to understand and communicat e effectively about this content? 1 + 3 × (1/10) + 9 × (1/100) + 2 × (1/1000). b. Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons. 5.NBT.4 Use place value understanding to round decimals to any place. I am learning to… 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 to solve decimal operation calculations. Fluently translate between powers of ten written as ten raised to a whole number exponent, the expanded form, and standard notation (103 = 10 x 10 x 10 = 1000) Explain the patterns in the placement of the decimal in the answer when multiplying or dividing a decimal number by powers of 10. Explain the relationship of the placement of the decimal point when a decimal is multiplied or divided by a power of 10.
