When you are absent from school, your substitute teacher can become an effective teacher aid if you provide them with the teacher tools they need to work effectively. So, prepare and keep a substitute's folder early in the year. Include general information like the class list, fire drill runes, seating charts, class rules, and more. Then all you have to do when you know you will be absent is to slip in the content you are currently studying or a class lesson plan, and your substitute will think you are a dream come true. And, when substitutes are well prepared and confident, there is less chance that the day will go awry.
