# Math: Extending Decimal Place Value to Thousandths and Applying Addition and Subtraction of Decimals to Data Analysis and Perimeter

### Suggested Time Frame: 15 Instructional Days

##### Focus TEKS

Decimal Place Value to Thousandths

• 5.2B compare and order two decimals to thousandths and represent comparisons using the symbols >, <, or =; – R RC1
• 5.2A represent the value of the digit in decimals through the thousandths using expanded notation and numerals; – S RC1
• 5.2C round decimals to tenths or hundredths. – S RC1

Add and Subtract Rational Numbers – Whole Numbers and Decimals

• 5.3K add and subtract positive rational numbers fluently; – R RC2 [whole numbers, decimals to thousandths in this unit]
• 5.3A estimate to determine solutions to mathematical and real-world problems involving addition, subtraction, multiplication, or division; – S RC2

Perimeter – Add and Subtract to Solve Problems with Decimals

• 5.4H represent and solve problems related to perimeter and/or area and related to volume. – R RC3 [whole number and decimal measurements in this unit]
• 2.9D determine the length of an object to the nearest [whole or decimal part of a] marked unit using rulers, yardsticks, meter sticks, or measuring tapes

Data Analysis – Add and Subtract to Solve Problems with Decimals

• 5.9C solve one- and two-step problems using data from a frequency table, dot plot, bar graph, stem-and-leaf plot, or scatterplot. – R RC4 [problems involving addition and subtraction of whole numbers and decimals in this unit]
• 5.9A represent categorical data with bar graphs or frequency tables and numerical data, including data sets of measurements in fractions or decimals, with dot plots or stem-and-leaf plots; – S RC4
##### Numeracy TEKS

Multiply and Divide Whole Numbers

• 5.3B multiply with fluency a three-digit number by a two-digit number using the standard algorithm; – S RC2
