Need some suggestions
Jul 31, 2018
We would like to create an activity that asks students to differentiate between Prime and Composite numbers from 1 to 1000. We would like to have the numbers randomly generated by SL (360). We were thinking of a drag and drop activity but aren't sure how to set that up. If the numbers are randomly generated variables, we can't assign fixed drop targets. On the other hand, if we created all of the draggable objects (not ideal since there would be 1000) we would need a way to tell SL to randomly select 25 of the 1000 objects each time a student tried the activity.
If anyone has any ideas and suggestions, we would love to hear them.
Thanks,
Chris
Here are all of the primes less than 1000:
{2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499, 503, 509, 521, 523, 541, 547, 557, 563, 569, 571, 577, 587, 593, 599, 601, 607, 613, 617, 619, 631, 641, 643, 647, 653, 659, 661, 673, 677, 683, 691, 701, 709, 719, 727, 733, 739, 743, 751, 757, 761, 769, 773, 787, 797, 809, 811, 821, 823, 827, 829, 839, 853, 857, 859, 863, 877, 881, 883, 887, 907, 911, 919, 929, 937, 941, 947, 953, 967, 971, 977, 983, 991, 997}
Any integer not on the list is composite.

Hello Chris,
Here is what I came up with.
WOW! Russell thank you for putting in all of that time and effort to help out! I can't thank you enough!!!
HI Russell,
I'm trying to decipher the JavaScript and can't figure out how it determines if the number is prime or composite. I went in and added correct and incorrect states to the drag items and SL is showing some even numbers as being prime.
Thanks again for your help!
Hi Chris,
I had to remove the submit interaction trigger and use some custom javascript to change the states.
Very cool! Thank you again for all of your help!
