Fifth Grade CCSS Progressions 5.NBT (Numbers in Base Ten) 4th grade Progression 4.NBT. 1 (Unit 2, Unit 4) Recognize that in a multidigit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 ÷ 70=10 by applying concepts of place value and division. 4.NBT.2 (Unit 2) Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meaning of the digits in each place, using >, =, and < symbols to record the results of comparisons. 4.NBT.3 (Unit 2, Unit 5) Use place value understanding to round multi-digit whole numbers to any place. 5th Grade CCSS 5.NBT.1(Unit5) Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left. 5.NBT.2(Unit 5) 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. Progressions Foundational Knowledge of Decimals: Students should have a strong understanding of the connection between fractions and decimals. They should also be able to understand and explain that decimals are an extension of the base-ten system. Students should understand that the value of each place is ten times the value of the place to the right (moving to the left the numbers are increasing 10 times). When moving to the right, the value of each place is divided by 10. Students should understand and be able to explain the following: When one factor in a multiplication sentence is a multiple of 10 you can use your understanding of place value patterns and basic facts to find the product. Why can you “add zeros” when multiplying by powers or multiples of 10? 6th Grade CCSS 6.NS.5 Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in realworld contexts, explaining the meaning of 0 in each situation. 6.NS.2 Fluently divide multi-digit numbers using the standard algorithm. 6.NS.3 Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. Proof/Reasoning that students should know: Example: 30x600=(3x10) x (6x100) =(3x6) x (10x100) = 18x1,000 =18,000 The number(s) in parenthesis behind each CCSS indicates the CCPS unit(s) in which the standard is located.

Fifth Grade CCSS Progressions 5.NBT (Numbers in Base Ten) 4th grade Progression 4.NBT.2 (Unit 2) Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meaning of the digits in each place, using >, =, and < symbols to record the results of comparisons. 5th Grade CCSS 5.NBT.3(Unit 5) Read, write and compare decimals to thousandths. a. Read and write decimals to the thousandths using base-ten numerals, number names, and expanded form, e.g. 347.392 = 3 x 100 + 4 x 10 + 7 x 1 + 3 x (1/10) + 9 x (1/100) + 2 x (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. Progressions Comparing decimals: Students should know that when comparing decimals they should compare like places, beginning in the place with the highest value. This will always work because of the structure of the base-ten system. Example: A tenth is greater than any number made of only hundredths because once you have ten hundredths it has to be recorded as 0.1 or one tenth. For example: 0.12 > 0.099 because 12 hundredth has one tenth while ninety nine thousandths has zero tenths. 6th Grade CCSS Understand ordering and absolute value of rational numbers. 6.NS.C.7a Interpret statements of inequality as statements about the relative position of two numbers on a number line diagram. For example, interpret –3 > –7 as a statement that – 3 is located to the right of –7 on a number line oriented from left to right. 6.NS.C.7b Write, interpret, and explain statements of order for rational numbers in real-world contexts. For example, write –3 oC > –7 oC to express the fact that –3 oC is warmer than –7 oC. 6.NS.C.7c Understand the absolute value of a rational number as its distance from 0 on the number line; interpret absolute value as magnitude for a positive or negative quantity in a real-world situation. For example, for an account balance of –30 dollars, write |–30| = 30 to describe the size of the debt in dollars. 6.NS.C.7d Distinguish comparisons of absolute value from statements about order. For example, recognize that an account balance less than – 30 dollars represents a debt greater than 30 dollars.

Fifth Grade CCSS Progressions 5.NBT (Numbers in Base Ten) 4th grade Progression 5th Grade CCSS 4.NBT.3 (Unit 2, Unit 5) Use place value understanding to round multi-digit whole numbers to any place. 5.NBT.4 (Unit 5) Use place value understanding to round decimals to any place. 4.NBT.5 (Unit 1) Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two digits numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. 5.NBT.5(Units 2 and 9) Fluently multiply multi-digit whole numbers using the standard algorithm. Progressions 6th Grade CCSS Make sure that students are fluent with rounding to the nearest whole. This will help students make sense of adding, subtracting, multiplying, and dividing decimals because estimates will help them to determine if their answers are reasonable. Work toward fluency: Connect to area models, open arrays, and the standard algorithm. Example: 15x14= 210 Open Array Area Model: 10 + 5 100 50 40 20 6.NS.2 Fluently divide multi-digit numbers using the standard algorithm. 6.NS.3 Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. 10 + 4 Both the area model and open array show 100+50+40+20=210 so 15x14=210 The standard algorithm also connects because the bottom of the area model and open array show 40+20=60 just like the first row in the standard algorithm. The top of the area model and open array show 100+50=150 just like the second row of the standard algorithm. Both result in adding the products of The number(s) in parenthesis behind each CCSS indicates the CCPS unit(s) in which the standard is located.

Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. 4.NBT.6 (Unit 1) Find whole number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area 5.NBT.6 (Units 3 and 9) Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. Students should understand how to decompose division problems into related division problems. Example: 48÷4=(40÷4) + (8÷4) so 48÷4=10+2 or 12 Students should completely understand simple division patterns using multiples of 10 and 100 in order to solve larger division problems. Students should understand how to use open arrays to decompose larger dividends based on place value. Example: 120÷4=30 6.NS.2 Fluently divide multi-digit numbers using the standard algorithm. 6.NS.3 Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. 10 + 10 + 10 = 30 4 40+ 40+ 40 =120 Students can also decompose numbers in multiple ways to divide: Example 1: 434÷7=62 Using the distributive proerty and partial quotients: Decomposed Example1 434=420+14=(60x7)+(2x7)=(60+2)x7=62x7 Example 2: 434÷7=62 0r using multiples of 10 (sometimes referred to as chimney division or partial products) Decomposed Example 2 The number(s) in parenthesis behind each CCSS indicates the CCPS unit(s) in which the standard is located.

Students need to learn to generate close factors for each place value to work towards using an efficient strategy and the standard algorithm(6.NS.2). 7 Pictures to support array drawings::51÷3=17 10 3 + 30 4.NBT.4 (Unit 2, Unit 6, Unit 9) Fluently add and subtract multi-digit whole numbers using the standard algorithm. 4.NBT.5 (Unit 1) Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two digits numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. 4.NBT.6 (Unit 1) Find whole number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on 5.NBT.7 (Unit5) 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. 7 21 51 4.NF.6 (Unit 8) Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram. 6th Grade CCSS = 17 Examples of partial quotients using close factors 10 3 Adding and Subtracting Decimals: Make sure students can make whole number estimates of the decimal equations. Refer back to the ideas and methods used by students to add and subtract whole numbers, including base-ten models, digi-blocks, and the standard algorithm. Make sure students have the conceptual understanding that only digits in like places can be added or subtracted because they have the same unit value. Encourage students to explain their strategies using place value language. Work towards procedural fluency. Multiplication and Division: Students should understand that multiplying two numbers, when one number is less than 1 can result in a product smaller than one of the factors. Students need opportunities to explain that 3x0.7 means three groups with 0.7 in each or 2.1(multiplication as grouping) or 0.7+0.7+0.7=2.1 (multiplication as repeated addition). Students should understand that when dividing two decimals the quotient is greater than the 6.NS.2 Fluently divide multi-digit numbers using the standard algorithm. 6.NS.3 Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.
