Students will demonstrate the concepts and skills that they have developed through these contexts and learning experiences. 

Intentionality…

The purpose of this assessment is for students to demonstrate their understanding of the following big ideas. 

• Situations involving addition and subtraction can be modelled using a number line;
• Integers include zero,  all whole numbers and their opposites;
• Integers represented on a number line show their relative distance from zero;
• Some addition and subtraction scenarios follow the structure of start, change and result;
• An integer can represent a change or a quantity;
• When a positive and a negative integer are added together, the result is positive if the absolute value of the positive integer is greater than the absolute value of the negative integer;
• Two integers can be represented as positions on a number line to determine the distance between them (magnitude); 
• The order in which a subtraction statement is written is important.

The independent assessment will allow students to demonstrate concepts and skills related to the following learning goals: 

• I will represent positive and negative integers. 
• I will describe contexts involving positive and negative integers. 
• I will add integers. 
• I will subtract integers. 
• I will use a model to represent the addition and subtraction of positive and negative integers. 
• I will demonstrate an understanding of the behaviour of addition and subtraction. 

Students might write and/or model their task independently. Students can also be interviewed by their teacher. 

An alternative assessment opportunity should be offered if this tool will not successfully capture what the student knows, understands or can do.
