Egyptians used a walking forward symbol in their hieroglyphics for addition and a walking backwards symbol for subtraction.
By adding in facing right for positive numbers and facing left for negative numbers we can use Egyptian hieroglyphic math to practice adding and subtracting signed integers. Walking is the verb; it is an operation (forward for addition, backward for subtraction). Negative or positive are adjectives modifying the integers; the direction you face when walking (left for negative, right for positive).
This is a beginning exercise for 6th and 7th graders just learning to do addition and subtraction with signed integers. Inside the zip file are an excel spreadsheet with the number line and practice problems, two different docx files with stick figures for walking, a lesson description, and some large print integers for the numberline.
