Good puzzle for kids to solve on 35s?  snaggs  09172013 I want to teach my 10 year old son some simple programming. Can anyone suggest a simple problem I could get him to solve using the 35s that has enough steps to be fun?

Re: Good puzzle for kids to solve on 35s?  Don Shepherd  09172013 How about guess the number, 1100? The calculator generates a random number and he tries to guess it, and it tells him how many guesses it took when he gets it. This has the added advantage of teaching him about a binary search.
Re: Good puzzle for kids to solve on 35s?  Namir  09172013 And you can do the reverse game, have your son guess a number between 1 and 100 and the calculator try to figure out the number. Perhaps the simplest program is having the calculator add integers from 1 to a specified upper limit and then comparing the result with Gauss's formula n(n+1)/2.

If I may suggest a modification to the suggestion by Csaba  population dynamics  w an emphasis on intersecting populations. The following URL(s) are very informative; Re: Good puzzle for kids to solve on 35s?  Namir  09172013 What is the link to that HP25 listing please?

Re: Good puzzle for kids to solve on 35s?  Matt Agajanian  09172013 Two games I can recommend are the wellknown 'Nimb' found in HP25C, HP33E and HP34C program manuals or here in MoHPC's Program Library or 'Sum of Digits Game' from the HP Digest article 'How Programmable Calculators Help Kids Learn.'

Re: Good puzzle for kids to solve on 35s?  David Hayden  09182013 It may be too advanced for a 10 year old, but finding prime factors of a number is fun too.
