Supported by Google Challenge of the Week November 26 – December 3, 2010 A teacher announces that a test will be given on one of the five days of next week, but tells the class, "You will not know which day it is until you are informed at 8 am of your 1pm test that day". Which day will be the exam given? Submit your solution to challenge[at]math.washington.edu. The winner of this week's Challenge Problem receives a gift certificate for Baskin Robbins Ice Cream! The Challenge Problem is posted every Friday in the afternoon (every other Friday over the summer). For questions, comments, or suggestions for future challenge problems, or to be added/removed from the email list: please email challenge[at]math.washington.edu. The challenge problem is maintained by Mauricio Duarte, Sudip Paul and Erik Slivken.
Yummy Math | We provide teachers and students with mathematics relevant to our world today … Creativity techniques and creative tools for problem solving This A to Z of Creativity and Innovation Techniques, provides an introduction to a range of tools and techniques for both idea generation (Creativity) and converting those ideas into reality (Innovation). Like most tools these techniques all have their good and bad points. I like to think of these creativity and innovation techniques as tools in a toolbox in much the same way as my toolbox at home for DIY. It has a saw, spanner, hammer, knife and all sorts of other things in it, they are all very useful, but you have to pick the right tool (creativity / Innovation technique) for each job. This site will try and provide a little guidance along with each tool to let you know whether it's best used for cutting paper or putting in nails. For the future, the aim is to also have sub-categories which will identify Techniques for; Problem Definition - including problem analysis, redifinition, and all aspects associated with defining the problem clearly.

www.illustrativemathematics.org/standards/k8 Illustrated Standards Count to 100 by ones and by tens. (see illustrations) Count forward beginning from a given number within the known sequence (instead of having to begin at 1). (see illustrations) Write numbers from 0 to 20. Understand the relationship between numbers and quantities; connect counting to cardinality. When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object. Understand that the last number name said tells the number of objects counted. Understand that each successive number name refers to a quantity that is one larger. Count to answer “how many?” Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies. Compare two numbers between 1 and 10 presented as written numerals. Fluently add and subtract within 5. Recognize area as additive.
