We have a new lesson aimed at 2nd-4th graders (though also may be interesting for older grades) on Square Numbers we just shared at trianglemathinstitute.com/math and directly at tinyurl.com/mathInstSquareNumbers . #mtbos

There's an easy way to take any positive integer and find the number of factors it has; just do a prime factorization, add 1 to each of the exponents, and multiply those incremented exponents. We show you why and how in our video tinyurl.com/mathInstNumFactors. #mtbos #numberTheory

We just finished hosting two sessions of the #mathKangaroo #mathCompetition serving about 60 students grades 1-11. #mtbos mathkangaroo.org/mks/
