Georgia 4.NR.5

4.NR.5 is a Georgia mathematics standard. These are the expectations under it.

• 4.NR.5.1

  Demonstrate and explain the concept of equivalent fractions with denominators of 10 and 100, using concrete materials and visual models. Add two fractions with ...

• 4.NR.5.2

  Represent, read, and write fractions with denominators of 10 or 100 using decimal notation, and decimal numbers to the hundredths place as fractions, using conc...

• 4.NR.5.3

  Compare two decimal numbers to the hundredths place by reasoning about their size. Record the results of comparisons with the symbols >, =, or <, and justify th...

01

What Students Need to Do

Students solve everyday problems by adding, matching, and comparing tenths and hundredths. They use visual models to connect fractions such as 6/10 and 60/100 with decimals such as 0.6 and 0.60.

02

What Mastery Looks Like

Students use hundred grids, fraction strips, or number lines to represent and solve a situation. They correctly explain equivalence and comparisons using place value or matching-sized parts.

03

Common Misconceptions

Students may think more decimal digits make a number larger, so 0.45 is greater than 0.5. They may compare numerators only or miss that 5/10, 50/100, and 0.50 name the same amount.

How to Assess It

Give this exit ticket: “Maya walked 3/10 mile, then 25/100 mile. How far did she walk, and is it more than 0.5 mile? Show a model.”

1. 01

   Give pairs hundred grids to shade 4/10 and 35/100, then combine the shaded amounts and write a fraction and decimal.

2. 02

   Ask students to explain why 7/10 is greater than 68/100 using a drawing, place value language, or both.

3. 03

   Play Compare and Capture by turning over decimal cards, modeling each number on grids, and keeping both cards when the comparison is correct.

4. 04

   Use store prices to compare $0.60 and $0.56, then find the total cost of two items priced under one dollar.

• 5.NR.4.4

  Solve problems involving addition and subtraction of decimal numbers to the hundredths place using a variety of strategies.

• 3.PAR.3.6

  Solve practical, relevant problems involving multiplication and division within 100 using part-whole strategies, visual representations, and/or concrete models.

• 4.NR.4

  Solve real-life problems involving addition, subtraction, equivalence, and comparison of fractions with denominators of 2, 3, 4, 5, 6, 8, 10, 12, and 100 using ...

• 4.NR.2

  Using part-whole strategies, solve problems involving addition and subtraction through the hundred-thousands place, as well as multiplication and division of mu...
