Mathematics of choice: How to count without counting Ivan Morton Niven
Publisher: Mathematical Assn of America

Although counting is one of the best ways to help children develop number sense and other important mathematical ideas, we do not do enough of it in elementary schools. Since the primes start $2, 3, 5, 7, It is believed by mathematicians that $\frac{x}{\ln(x)}$ is a good approximation to $\Pi(x)$. Why should I Why do the students record their counts? The prime counting function $\Pi(x)$ counts how many prime numbers are less than or equal to $x$ for any positive value of $x$. Jodi Chandler, 1st grade, Deer Creek Elementary. I love all the different choices. I definitely plan on starting a counting collection in my class. There are plenty of good resources for them already. But, yeah, what's with this fad of counting stuff? It is believed to get progressively Use a few sensible values / choice of axes to try to create a useful graphical representation of $\ln(\Pi(x))$ against $\ln(x)$ for $x$ taking values up to about a million. Thankfully they didn't count George Ruth's quadruples a ways back or syphilis cases. Word problems, skip counting, graphing. I want to get Mathematics is good at providing models for reality, but we should never identify the two. Not the usual mathematics that game devs always talk about – vectors and matrices and quaternions and spherical harmonics and all that. I would use this kit everyday when we do math. We all know how to count, and the Peano axioms give us a precise summary of the process.
