I'll be honest, I spent the 300 coins to answer the question because I couldn't figure out how to use the digit 3 twice, otherwise, I would have had the answer right. It still said, "Congratulations, you guessed right".
Other than that, the problems are challenging because you have to read them carefully to use. I think I would use the KFCW form to solve many of the problems if I assigned them in class..
K is for "What do you know" or what information did they give you.
F is for "What do you have to find.
C is for "What things do you have to consider or think about to answer it." Things like formulas, extra steps, operations, etc.
W is for the "Work"
I always require them to do the KFCW so they learn a systematic way of solving word problems. Too often, the students who struggle with the basics also struggle with word problems and this method helps them so they don't just guess and throw in the numbers to use in some way.
