## Goldbach Strong Conjecture (Even numbers > 2 = the sum of exactly two primes)

Every even integer greater than two can be expressed as a sum of two primes, is one of the most enduring unsolved problems of mathematics.

## Bizz Buzz Prime (Multiples of 3, 7, and primes)

I played a game a few years ago with the children that was a challenging exercise in multiples of 3 and 7.

## Super Bowl Statistics, Primes, Roman Numeral Challenges

Super Bowl 53 was the 11th Super Bowl trip for the New England Patriots. One team has enjoyed more than 20% of championship games played, played in the last three consecutive Super Bowls, and four of the last five, winning a total of six Super Bowls.

## Divisibility Rules: 2, 3, 4, 5, 6, 7, 9, 10,11,13 and higher primes

After the children became factor masters last week, we introduced a set of divisibility rules for the numbers 2, 3, 5, 6, 9, and 10 for the younger children since these rules are easy to learn and apply to any number. See these rules below:

## Factor Pairs Method--Inverse Variation

Last week we learned about free fall and Newton’s equation:
