Play Together, Learn Together: Roll, Pick, and Add Dice Games describes math games and algebraic alakazams for players in grades 1, 2, 3, and up into high school.

   Part of this eBook is about playing the games. 1st-graders can play the easier games.

   Part of this eBook is about Curriculum Construction Kits that you can use to construct

   instructional stuff related to math dice games.

Playing Roll, Pick, and Add reinforces adding 1-digit numbers, adding a 1-digit number to a 2-digit number, greater than, less than, equal to, and possibly other math thingamajigs that didn't occur to us as we wrote this blurb.

We think Roll, Pick, and Add is a rich source of probability and statistics alakazams appropriate for algebra and statistics courses.

pdf Explore/Investigate: Products of Proper Factors

1795 downloads

PDF file. We frequently awake during the night wondering about mathemagical alakazams. Sometimes we leap out of bed and jot down notes to remind us to check out an idea. One night we woke in the wee hours wondering about products of proper factors of natural numbers. We eased out of bed and wrote a note to look it up on the Internet. Later that day, we cranked up our computer and searched for

products of proper factors

We found zilch, nada, nothing about products of proper factors of numbers. We did another search:

sums of proper factors [12 million hits!] 

On the Internet, there is much ado about sums of proper factors of natural numbers, but we did not find anything about products of proper factors of natural numbers.

Aha! Is this unexplored territory? (We don't know.) In this 52-page eBook, we explore products of proper factors. We leave much exploring undone and hope that YOU and YOUR STUDENTS will continue the exploration.
