Are we having fun yet? We are! Let's solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Common Core Standard: 4.MD.A.2
To "make change" means to be able to give people the correct amount back in dollars and cents when paying for something. This is one of the most common and important skills haivng to do with unit conversion. Let's do it!
We're moving between metric units of distance measurement (meters and kilometers) in this word problem. Hint: when doing any word problem, be sure and make note of the unit measurement wanted in the answer!
Remember that it's always easier to convert everything to like units before tackling a unit conversion word problem. That way your comparing apples to apples. Go for it...we'll explain as we work through it!
We're moving between units of weight in this word problem. Ever get in an elevator with a bunch people and wonder to yourself, "How many people can this elevator safely hold?" Yeah, us too. You can solve that problem now.
