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.
how do you the explain answer to a 3rd grader
Number each stack with a post-it note. Each stack is labeled 1 hour. The child can then count the hours.
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.
........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
We know that Sara takes 1 hour to make 5 cards. So, to find out how many sets of 5 cards she made, we divide the total number of cards made on Tuesday (25) by the number of cards she makes in 1 hour (5).
To make it easier, you can use objects like buttons or blocks to represent the cards. For example, if you have 25 buttons, you can group them into sets of 5, just like Sara did.
Start by making 5 groups of 5 buttons, and count how many buttons you used. You'll see that you used all 25 buttons. That means Sara made 25 cards in one hour, just like on Tuesday.
So, the answer to the question is that Sara spent 1 hour working on the cards on Tuesday.
