Passage of time - Christmas
You are baking Christmas cupcakes. They need to cook for 3 hours - if you put them in the oven at 3:00pm, when will you take them out?
You need to put cookies out for Santa at 10:00pm. Right now it is 5:00pm. How many hours until you put cookies out?
You are going to the mall to buy Christmas presents. It is 5:00. You need to be home by 7:30 for dinner. How much time do you have?
