Standard for Mathematical Practice Essential Question IS WHAT I LEARNED IN KINDERGARTEN ALL I REALLY NEED TO KNOW? (see Robert Fulghum’s guide for Global Leadership) “All I really need to know about how to live and what to do and how to be, I learned in Kindergarten. Wisdom was not at the top of the graduate school mountain, but there in the sand pile at school.” Define a function (in a mathematical sense) A function is a set of ordered pairs for which each element of the domain (input) is paired with exactly one element of the range (output). For example: f(x) = 5 - x x 5-x f(x) x 5 4 3 2 1 0 f(x) 0 1 2 3 4 5 Look through the Kindergarten Common Core Mathematics content standards and find an example of a function. Do you think there was a reason we chose the function f(x) = 5 – x? Number and Operations in Base-Eight How does this standard relate to the structure of Base8? Base-10? Aunt Martha’s Cupcakes Aunt Martha has 5 trays of cupcakes. She describes how they were arranged: There are 100 total cupcakes on the trays. The first and second trays have 52 cupcakes, the second and third trays have 43 cupcakes, the third and fourth trays have 34 cupcakes, and the fourth and fifth trays have 30 cupcakes. How many cupcakes are in each tray? Find the ones digit of… 2 2013
