sara is making birthday cards. she takes 1 hour to make 5 cards. on tuesday, sara made 25 cards. how long did sara spend working on the cards on tuesday?
how do you the explain answer to a 3rd grader

You could use 25 file cards (or old greeting cards?) to represent the birthday cards. Ask the child to make stacks with 5 cards in each stack.
Number each stack with a postit note. Each stack is labeled 1 hour. The child can then count the hours. 
5 cards in 1 hour
25 cards in 5 hours
5/hour + 5/hour + 5/hour + 5/hour + 5/hour = 25 cards/5 hour
I'm not sure what a 3rd grader is able to do as far as division or multiplication. 
ok look in this problem it says 5 cards she makes in a hour so now we how to figure out how many hours did she spent making 25 cards in Tuesday so we start by putting 5 cards=1hryou would have to write
........5 cards=1hr it until we get to 25
........5 cards=1hr cards then count how
........5 cards=1hr many hours did it took
........5 cards=1hr
........25cards=5hrs (P.S. 25divided by 5 equals 5 or 5 times 5 equals 25 so 5 is the answer) sincerely.. 8th grader
