  • Unit 5  Math Goals:

    1.  The students will understand, represent, and solve problems involving addition and subtraction.

    •   Visualize, represent, and solve put together/take apart story problems with both addends unknown, and find all the possible combinations.
    •   Prove that all of the possible two-addend combinations of a number have been found.
    •   Visualize, represent and solve put together/take apart story problems with one addend unknown, and record solution strategies.
    •   Visualize, represent, and solve put together/take apart story problems with the total/result unknown.
    •   Visualizing, representing, and solving a put together/take apart problems about unknown change.
    •   Solve problems with one, two, or more addends unknown.
    •   Use numbers, pictures, words and/or notation to represent a solution to a problem.
    • Consider whether order matters in addition.
    • Adding and subtracting within 20, deomonstrating fluency within 10.
    • Generate a story context to match a given equation.

     2.  The Students will understand equivalence.

    •  Determine equivalent expressions for a given expression.  (7 + 8= 10 + ___)
    •  Generate equivalent expressions for a given number.
    •  UsinUnderstand that equal sign represents equivalence.
    •  Interpreting and using standard notation (<,>,+,-,=).
    •  Determining whether equations are true or false.

    3.  Understanding place value.

    • Determine the 2 digit number that represents a quantity organized into groups of ten and some number of ones.
    • Recognize that the first didit of a 2-digit number designates the number of groups of tens and the second digit designates the number of ones.
    • Use an equation to represent a 2-digit number as the sum of a multiple of ten and some number of ones (22= 20+2).
