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
