• Mathematics • 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).
