# Math (TAG): Place Value to One Billion

### Suggested Time Frame: 10 Instructional Days

##### Focus TEKS

4(2)  Number and operations. The student applies mathematical process standards to represent, compare, and order whole numbers and decimals and understand relationships related to place value. The student is expected to:

• (A)  interpret the value of each place-value position as 10 times the position to the right and as one-tenth of the value of the place to its left; – Supporting RC1
• (B)  represent the value of the digit in whole numbers through 1,000,000,000 and decimals to the hundredths using expanded notation and numerals; – Readiness RC1
• (C)  compare and order whole numbers to 1,000,000,000 and represent comparisons using the symbols >, <, or =; – Supporting RC1
• (D)  round whole numbers to a given place value through the hundred thousands place; – Supporting RC1
##### Numeracy TEKS

Building Fluency with Addition and Subtraction of 2- and 3-Digit Numbers (Suggested: 10 days)

• 3.4A solve with fluency one-step and two-step problems involving addition and subtraction within 1,000 using strategies based on place value, properties of operations, and the relationship between addition and subtraction; – R RC2
• 3.4B round to the nearest 10 or 100 or use compatible numbers to estimate solutions to addition and subtraction problems; – S RC2
##### Spiral Review TEKS

Revisiting Measurement (Time, Weight, Liquid Volume) (Suggested: 10 days)

• 3.7C determine the solutions to problems involving addition and subtraction of time intervals in minutes using pictorial models or tools such as a 15-minute event plus a 30-minute event equals 45 minutes; – S RC3 [including relationships between minutes and hours]
• 3.7E determine liquid volume (capacity) or weight using appropriate units and tools. – S RC3
• 3.7D determine when it is appropriate to use measurements of liquid volume (capacity) or weight; – S RC3
• 3.7A represent fractions of halves, fourths, and eighths as distances from zero on a number line; – S RC1 [recognizing the intervals on the scales of measurement tools]
