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?

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 post-it 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
