Math: Applying Computation Skills to Data Analysis and Personal Financial Literacy

Suggested Time Frame: 10 Instructional Days

        

Focus TEKS

Data Analysis

  • 4.9A represent data on a frequency table, dot plot, or stem-and-leaf plot marked with whole numbers and fractions; – R RC4 [focus on stem-and-leaf plots in this unit]
  • 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

Personal Financial Literacy

  • 4.10A distinguish between fixed and variable expenses; – S RC4
  • 4.10B calculate profit in a given situation; – S RC4
  • 4.10C compare the advantages and disadvantages of various savings options; – NT
  • 4.10D describe how to allocate a weekly allowance among spending; saving, including for college; and sharing; – NT
  • 4.10E describe the basic purpose of financial institutions, including keeping money safe, borrowing money, and lending. – S RC4
Computational Fluency TEKS

Estimation (Use to verify reasonableness of products and quotients)

  • 4.4G round to the nearest 10, 100, or 1,000 or use compatible numbers to estimate solutions involving whole numbers; – S RC2

Multiply Whole Numbers

  • 4.4B determine products of a number and 10 or 100 using properties of operations and place value understandings; – S RC2
  • 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

Divide Whole Numbers

  • 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
Spiral Review TEKS

Input-Output Tables

  • 4.5B represent problems using an input-output table and numerical expressions to generate a number pattern that follows a given rule representing the relationship of the values in the resulting sequence and their position in the sequence; – R RC2

Measurement Conversions Using Tables

  • 4.8A identify relative sizes of measurement units within the customary and metric systems; – S RC3
  • 4.8B convert measurements within the same measurement system, customary or metric, from a smaller unit into a larger unit or a larger unit into a smaller unit when given other equivalent measures represented in a table; – S RC3

Perimeter and Area Formulas

  • 4.5D solve problems related to perimeter and area of rectangles where dimensions are whole numbers. – R RC3
  • 4.5C use models to determine the formulas for the perimeter of a rectangle (l + w + l + w or 2l + 2w), including the special form for perimeter of a square (4s) and the area of a rectangle (l x w); – NT

Represent and Solve Measurement and Data Problems

  • 4.5A represent multi-step problems involving the four operations with whole numbers using strip diagrams and equations with a letter standing for the unknown quantity; – R RC2 [This TEKS can be paired with 4.8C so long as the problem involves whole numbers only]
  • 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 [word problems may include measurement conversions]
  • 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
