applying symbols of operations- addition and subtraction

The First Grade Butterfly Mathematicians are developing their understanding of the operations of addition and subtraction, their understanding of the mathematical symbols of operations (+ and -), and their addition and subtraction fact fluency.

Utilizing the Math War app on the student iPads, the First Grade Butterfly Mathematicians cooperatively identify the appropriate symbol of operation (+ or -) to complete an equation.

With each problem, the math partners alternate between "solving and explaining" and "monitoring and completing" the equation.

With each problem...
1. The "monitoring and completing" partner reads the equation.
2. The "solving and explaining" partner determines the operation needed to complete the equation and restates the equation with the determined operation.
3. The "monitoring and explaining" partner monitors the accuracy of the identified operation needed to complete the equation and restates the equation after moving the corresponding operational symbol into the equation.  (If the "monitoring and completing" partner disagrees with the operation identified by the "solving and explaining" partner- he/she prompts the "solving and explaining" partner to explain his/her process and thinking-reasoning.  The partners cooperatively determine the accurate operation needed to complete the equation,)
