Suggested Time Frame: 17 Instructional Days

        

Focus TEKS

Multiply and Divide Whole Numbers (Represent Problems and Solve Them)

  • 5.4B represent and solve multi-step problems involving the four operations with whole numbers using equations [and strip diagrams] with a letter standing for the unknown quantity; – R RC2
    • 5.3A estimate to determine solutions to mathematical and real-world problems involving addition, subtraction, multiplication, or division; – S RC2
    • 5.3B multiply with fluency a three-digit number by a two-digit number using the standard algorithm; – S RC2
    • 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 RC2

Measuring and Calculating Volume

  • 5.4H represent and solve problems related to perimeter and/or area and related to volume. – R RC3
    • 5.4G use concrete objects and pictorial models to develop the formulas for the volume of a rectangular prism, including the special form for a cube (V = l x w x h, V = s x s x s, and V = Bh); and – NT
    • 5.6A recognize a cube with side length of one unit as a unit cube having one cubic unit of volume and the volume of a three-dimensional figure as the number of unit cubes (n cubic units) needed to fill it with no gaps or overlaps if possible; – S RC3
    • 5.6B determine the volume of a rectangular prism with whole number side lengths in problems related to the number of layers times the number of unit cubes in the area of the base. – S RC3
Numeracy TEKS

Add and Subtract Rational Numbers

  • 5.3K add and subtract positive rational numbers fluently; – R RC2 [whole numbers, fractions and mixed numbers with like and/or unlike denominators]

Grade 4 Add and Subtract Decimals

  • 4.4A add and subtract whole numbers and decimals to the hundredths place using the standard algorithm; – R RC2
Spiral Review TEKS

Prime and Composite Numbers

  • 5.4A identify prime and composite numbers; – S RC1

Grade 4 Decimal Place Value, Addition, and Subtraction

  • Grade 4 Represent and Compare Decimals to Hundredths
    • 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; – R RC1 [focus is on decimal place value in this unit, though numbers can extend up to review whole number place value as well]
    • 4.2E represent decimals, including tenths and hundredths, using concrete and visual models and money; – S RC1
    • 4.2F compare and order decimals using concrete and visual models to the hundredths; – S RC1
    • 4.2G relate decimals to fractions that name tenths and hundredths; – R RC1
    • 4.2H determine the corresponding decimal to the tenths or hundredths place of a specified point on a number line. – S RC1
    • 4.3G represent fractions and decimals to the tenths or hundredths as distances from zero on a number line. – S RC1
  • Grade 4 Add and Subtract to Solve Problems with Decimals to Hundredths
    • 4.4A add and subtract whole numbers and decimals to the hundredths place using the standard algorithm; – R RC2 [focus is on adding and subtracting decimals in this unit]
    • 4.8C solve problems that deal with measurements of length, intervals of time, liquid volumes, mass, and money using addition, subtraction, multiplication, or division as appropriate. – R RC3 [focus is on measurement contexts that involve adding and subtracting decimals]
    • 4.9B solve one- and two-step problems using data in whole number, decimal, and fraction form in a frequency table, dot plot, or stem-and-leaf plot. – S RC4
