Quarter 2

NC.5.NBT.6 - Find quotients with remainders when dividing whole numbers with up to four-digit dividends and two-digit divisors using rectangular arrays, area models, repeated subtraction, partial quotients, and/or the relationship between multiplication and division.

NC.5.NF.4 - Apply and extend previous understandings of multiplication to multiply a whole number by a fraction, including mixed numbers.

• Use area and length models to multiply [a fraction by a whole number], with the denominators 2, 3, 4.

• Explain why multiplying a given number by a fraction greater than 1 results in a product greater than the given number and when multiplying a given number by a fraction less than 1 results in a product smaller than the given number.

NC.5.NF.3 - Use fractions to model and solve division problems.  

• Interpret a fraction as an equal sharing context, where a quantity is divided into equal parts.  

• Model and interpret a fraction as the division of the numerator by the denominator. 

• Solve one-step word problems involving division of whole numbers leading to answers in the form of fractions and mixed numbers, with denominators of 2, 3, 4, 5, 6, 8, 10, and 12, using area, length, and set models or equations. 

NC.5.NF.7 - Solve one-step word problems involving division of unit fractions by non-zero whole numbers and division of whole numbers by unit fractions using area and length models, and equations to represent the problem.

NC.5.NBT.1 - Explain the patterns in the place value system from one million to the thousandths place.

• Explain that in a multi-digit number, a digit in the ones 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.

• Explain patterns in products and quotients when numbers are multiplied by 1,000, 100, 10, 0.1, 0.01 and/or divided by 10 and 100.

NC.5.NBT.3 - Read, write, and compare decimals to thousandths.

• Write decimals using base-ten numerals. number names, and expanded form.

• Compare two decimals to thousandths based on the value of the digits in each place, using >,=, and < symbols to record the results of comparisons.

NC.5.NF.1 - Add and subtract fractions, including mixed numbers, with unlike denominators using related fractions: halves, fourths and eighths; thirds, sixths, and twelfths; fifths, tenths, and hundredths.

• Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers.

• Solve one- and two-step word problems in context using area and length models to develop the algorithm.  Represent the word problem in an equation.
