Great basic extension problem for multiplication. I’m confused, however, about the hint. It’s also worth mentioning that the total number of carrots is not limited to 0-9
I may have been sloppy on my language. Perhaps I should have said “digits” instead of “numbers.” So that 18 is a number that uses two digits “1” and “8” to make a number.
That does it! Thanks Chase…for the comment and the task.
I went ahead and updated the problem to say digits instead of numbers.
This is a great website! It teaches them new skills every time they do this. I totally understand the hint.
Thanks for this (and all you all do!) Used this as a warm up in 4th grade, then sent kids home to work with family on problem of “How many diff. combinations are there following these rules?” Great opportunity to make an organized chart and think from extremes (biggest to smallest or vise versa).
I’m In 3rd Grade And This Is To Easy Please Make These Harder For Us.
