How many more gallons of fuel does Mr. George need to fill his car to capacity? This word problem uses the unknown addend strategy to get scholars subtracting and thinking about the relationship between mathematical operations. There is a step-by-step explanation and answer directly below the problem, so if you print this out you should cover up the bottom part as learners try this on their own. The word capacity may be a new one for some.
