Reflection: Adjustments to Practice Those Negative Numbers - Section 2: Activity 1


Some suggestions about talking and writing “signed numbers”:  

  1. I always use, and have students use, the terms positive number and negative number instead of plus or minus.

  2. I try to use the word subtraction instead of minus to refer to the operation of taking away a quantity from another quantity. This is to help students distinguish between the two different meanings of the "minus" sign.

  3. We know that the minus sign (“-”) is used both as a sign of subtraction, the operation, and as a sign indicating a negative number. I like to use, and I motivate students to use in their writing, a superscript negative sign (and positive sign) to distinguish it from the subtraction sign (“-5” or “+5”)
