This is very common! Help them memorize that two negatives make a positive, while one positive and one negative make a negative. Practice with simple examples like (-2) × (-3) = 6 and (-2) × 3 = -6 until it becomes automatic.
Explain absolute value as distance from zero on a number line. Both 5 and -5 are exactly 5 steps away from zero, so |5| = |-5| = 5. Use real examples like 'how far did you walk?' - it doesn't matter which direction, the distance is always positive.
Start by clearly defining what positive and negative mean in each problem. For temperature: positive = above zero, negative = below zero. For money: positive = earning/having, negative = spending/owing. For elevation: positive = above sea level, negative = below sea level.
Sign rules are crucial - students must understand that adding a negative is the same as subtracting a positive, and subtracting a negative is the same as adding a positive. Master this concept first, then tackle multiplication and division sign rules.
They should be comfortable with basic addition and subtraction of integers, understand what negative numbers represent, and know order of operations (PEMDAS). If they struggle with simpler integer problems, review those concepts before attempting this advanced worksheet.
