Math: Introducing Multiplication and Division Concepts

Suggested Time Frame: 17 Instructional Days

        

Focus TEKS

Skip Counting

  • 2.5A determine the value of a collection of coins up to one dollar [pennies, nickels, dimes, and quarters]
    • 2.5B use the cent symbol, dollar sign, and the decimal point to name the value of a collection of coins

Developing the Concepts of Multiplication and Division

  • 2.6 The student applies mathematical process standards to connect repeated addition and subtraction to multiplication and division situations that involve equal groupings and shares.
    • 2.6A model, create, and describe contextual multiplication situations in which equivalent sets of concrete objects are joined
    • 2.6B model, create, and describe contextual division situations in which a set of concrete objects is separated into equivalent sets
Computational Fluency TEKS

Two-Digit Addition and Subtraction

  • 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

Skip Counting – Coins

  • 2.5A determine the value of a collection of coins up to one dollar
    • 2.5B use the cent symbol, dollar sign, and the decimal point to name the value of a collection of coins
Spiral Review TEKS

Measure Time

  • 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.

Addition and Subtraction [Solving, Explaining, and Representing]

  • Solving
    • 2.4C solve one-step and multi-step word problems involving addition and subtraction within 1,000 using a variety of strategies based on place value, including algorithms [Use CGI problem types based around needs of your class]
  • Explaining
    • 2.1D communicate mathematical ideas, reasoning, and their implications using multiple representations, including symbols, diagrams, graphs, and language as appropriate
    • 2.1G display, explain, and justify mathematical ideas and arguments using precise mathematical language in written or oral communication
  • Representing
    • 2.4D generate and solve problem situations for a given mathematical number sentence involving addition and subtraction of whole numbers within 1,000
    • 2.7C represent and solve addition and subtraction word problems where unknowns may be any one of the terms in the problem
