Financial Calculators | DonnaYoung.org - Math HOW MANY VALENTINES? http://www.learner.org/teacherslab/math/patterns/valentines/handshakes1_act.phtml Happy Valentine's Day! This problem with a Valentine's Day theme is one of several presented as part of the "Patterns in Mathematics" section of the Teacher's Lab, from The Annenberg/CPB Math and Science Project. It is intended for use at a wide range of grade levels. Very young students can handle this problem for small numbers by acting it out and using manipulatives. By fourth grade, students can begin to make some abstractions. By eighth grade, they can apply a formula after sufficient work with manipulatives, tables, and diagrams. And the problem, with arbitrarily large numbers, remains appropriate into adulthood.
