# Math (TAG): Whole Number Multiplication and Division; Representing and Solving Multi-Step Problems with All Operations

### Suggested Time Frame: 13 Instructional Days

##### Focus TEKS

Multiplication and Division- Representing and Solving

• 5.4B  Represent and solve multistep problems involving the four operations with the whole numbers using equations with a letter standing for the unknown quantity- R
• 5.3A  Estimate to determine solutions to mathematical and real-world problems involving addition, subtraction, multiplication, or division – S
• 5.3B  Multiply with fluency a three-digit number by a two-digit number using the standard algorithm- S
• 5.3C  Solve with proficiency for quotients of up to a four-digit dividend by a two-digit divisor using strategies and the standard algorithm- S
##### Computational Fluency TEKS

Divide Whole Numbers: Computation

• 4.4F use strategies and algorithms, including the standard algorithm, to divide up to a four-digit dividend by a one-digit divisor; – S RC2 [include divisibility rules]

Multiply Whole Numbers – Computation

• 4.4D use strategies and algorithms, including the standard algorithm, to multiply up to a four-digit number by a one-digit number and to multiply a two-digit number by a two-digit number. Strategies may include mental math, partial products, and the commutative, associative, and distributive properties; – S RC2
##### Spiral Review TEKS

Whole Number and Decimal Place Value

• 5.2A  Represent the value of the digit in decimals through the thousandths using expanded notation and numerals- S
• 4.2A   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 S
• 4.2B   represent the value of the digit in whole numbers through 1,000,000,000 and decimals to the hundredths using expanded notation and numerals
• 5.2B  Compare and order two decimals to thousandths and represent comparisons using the symbols >, <, or = – R
• 4.2C  compare and order whole numbers to 1,000,000,000 and represent comparisons using the symbols >, <, or =; – S
• 5.2C  Round decimals to tenths or hundredths – S

Addition, and Subtraction Whole Numbers and Decimals

• 5.3K  Add and subtract positive rational numbers [decimals and whole numbers in this unit] fluently- R
