    Knowledge/skill statement 1
Understands the concept of an equation
K(ME,158;CE,189;S1E,62;T1I)
    
Related assessment item(s):
     Find the correct mass to balance the scale (T2)
    
Performance expectation(s):
    Expresses mathematical relationships using equations (M)

Understands that an equality relationship between two quantities remains the same as long as the same change is made to both quantities (S1)

    
Common Core Reference:
    K.OA.1; 1.OA.7
K.OA.1 Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

1.OA.7 Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
