Math: Revisiting Fair Shares and Equal Partitions

Suggested Time Frame: 12 Instructional Days

        

Focus TEKS

Representing and Counting Fractional Parts (Models, Pictures, and Words – No Fraction Notation)

  • 2.3B explain that the more fractional parts used to make a whole, the smaller the part; and the fewer the fractional parts, the larger the part
    • 2.3A partition objects into equal parts and name the parts, including halves, fourths, and eighths, using words
    • 2.3C use concrete models to count fractional parts beyond one whole using words and recognize how many parts it takes to equal one whole
    • 2.3D identify examples and non-examples of halves, fourths, and eighths
Numeracy TEKS

Counting Patterns (Suggested: 3 days)

  • RRISD 2.7B Skip count forward and backward by ten and one hundred from any given number up to 1,000

Building Fluency with Addition and Subtraction within 20 (Suggested: 9 days)

  • 2.4A recall basic facts to add and subtract within 20 with automaticity
Spiral Review TEKS

Creating, Solving, and Representing Story Problems (Suggested: 12 days)

  • Computation
    • 2.4B add up to four two-digit numbers and subtract two-digit numbers using mental strategies and algorithms based on knowledge of place value and properties of operations
  • Problem Solving
    • 2.4C solve one-step and multi-step word problems involving addition and subtraction within 1,000 [120 in this unit] using a variety of strategies based on place value, including algorithms
    • 2.4D generate and solve problem situations for a given mathematical number sentence involving addition and subtraction of whole numbers within 1,000 [120 in this unit].
    • 2.10C write and solve one-step word problems involving addition or subtraction using data represented within pictographs and bar graphs with intervals of one
  • Representing
    • 2.7C represent and solve addition and subtraction word problems where unknowns may be any one of the terms in the problem

Telling Time (Ongoing)

  • 2.9G read and write time to the nearest one-minute increment using analog and digital clocks and distinguish between a.m. and p.m.
