1st Grade Numbers

  • Combinations to 10

    Making Ten - Using a Ten Frame is an introduction to decomposing numbers to ten.

     
    Math Monsters- The Making of Ten The math monsters work together to show combinations of ten.
     
    • MA 1.1.2 Operations: Students will demonstrate the meaning of addition and subtraction with whole numbers.
              * MA 1.1.2.b Use objects, drawings, words, and symbols to explain addition as parts of a whole 
    • MA 1.1.3 Computation: Students will compute fluently and accurately using appropriate strategies and tools.
               * MA 1.1 .3.d Use a variety of methods and tools to compute sums and differences (e .g., models, mental computation, paper-pencil)


    Fact Families

    A video about a group of numbers that are related to each other. This video teaches that numbers can be combined to create multiple equations.  
     
         
    • MA 1.3.3 Procedures: Students will use concrete. verbal. and visual representations to solvenumber sentences.
                   *MA 1.3.3.a Write number sentences to represent fact families
                   *MA 1.3.3.b Use concrete,pictorial, and verbal representations of the commutative property of addition

     
    Number Line

    This video shows students how to use a number line. When the Math Monsters run a towing company, they must devise a way to locate where cars have broken down on the road. Watch them perfect their system of landmark numbers to make their job easier. http://tinyurl.com/MathMonstersQuickTime
     
    • MA 1.1.1 Number System: Students will demonstrate, represent, and show relationships among whole numbers within the base-ten number system.
                   *MA 1.1.1.a Count,read,and write numbers 0 –100
                   *MA 1.1.1.i Compare and order whole numbers 0- 100
                   *MA 1.1.1.j Demonstrate relative position of whole numbers 0- 100 (e.g.,52 is between 50 and 60; 83 isgreater than 77)
     

    Parts/Whole ​

    Part Part Whole example to solve a problem.
     
       
    • MA 1.1.2 Operations: Students will demonstrate the meaning of addition and subtraction with whole numbers.
                   * MA 1.1.2.b Use objects, drawings, words, and symbols to explain addition as parts of a whole
                   * MA 1.1.2.d Use drawings, words, and symbols to explain subtraction as finding part of a whole
