Math: Applying Number Sense within 20 to the Study of Data

Suggested Time Frame: 15 Instructional Days

        

Focus TEKS

Counting and Representing Quantities to 20

  • 1.2A Recognize instantly the quantity of structured arrangements [10 or less]
  • 1.2B Use concrete and pictorial models to compose and decompose numbers up to 120 [20 in this unit] in more than one way as so many hundreds, so many tens, and so many ones
  • 1.2C Use objects, pictures, and expanded and standard forms to represent numbers up to 120 [20 in this unit]

Comparing and Ordering Quantities within 20

  • 1.2D Generate a number that is greater than or less than a given whole number up to 120 [20 in this unit]
  • 1.2E Use place value to compare whole numbers up to 120 [20 in this unit] using comparative language
  • 1.2F Order whole numbers up to 120 [20 in this unit] using place value and open number lines [number tracks in this unit]

Collect and Display Data

  • 1.8A Collect, sort, and organize data in up to three categories using models/representations such as tally marks or T-charts
  • 1.8B Use data to create picture and bar-type graphs
  • 1.8C Draw conclusions and generate and answer questions using information from picture and bar-type graphs
Computational Fluency TEKS

Number Sense

  • 1.2A Recognize instantly the quantity of structured arrangements [10 or less]

Kindergarten Counting Patterns

  • K.5 The student is expected to recite numbers up to at least 100 by ones and tens beginning with any given number [count by tens to 100 starting at 1 in this unit]

Counting Patterns

  • 1.5A Recite numbers forward and backward from any given number between 1 and 120 [20 in this unit]
Spiral Review TEKS

Kindergarten Addition and Subtraction Concepts

  • K.3B  solve word problems using objects and drawings to find sums up to 10 and differences within 10;
    • K.3A  model the action of joining to represent addition and the action of separating to represent subtraction;
    • K.3C  explain the strategies used to solve problems involving adding and subtracting within 10 using spoken words, concrete and pictorial models, and number sentences.

Counting Collections

  • 1.5A Recite numbers forward and backward from any given number between 1 and 120 [20 in this unit]
