Activities and discussions align with the Math Forum's Problems of the Week, but could be used to develop problem solving techniques in general. View more description and the syllabus: http://mathforum.org/pd/process/syllabus.html \|/ ***TI-POW INDEX PAGE http://mathforum.org/tpow/ti.pow.html These five tPoWs, freely accessible and modeled on the Math Forum's Problems of the Week, take advantage of TI-Nspire technology. Students are invited to use the link "Submit your answer" to share their solutions, and then "self-mentor" using specially designed hints and checks. \|/ As you browse the catalog, please take a moment to rate a resource, comment on it, review it -- join an existing conversation, or start a new discussion! ***FEATURED TOOL Tool: Scientific Notation http://mathforum.org/mathtools/tool/65515/ Hotmath By moving a decimal point to the right or left and multiplying by an appropriate power of 10, you can write a decimal number in many equivalent forms. Use this tool to explore equivalent forms of decimal numbers, and to write and multiply numbers in scientific notation. ***FEATURED TPOW tPoW: Heads and Tails http://mathforum.org/mathtools/tpow/64928/ Craig Russell How many times do you have to flip a coin to get at least one head and one tail? ***FEATURED TPOW TI-PoW: Mauna Loa http://mathforum.org/mathtools/tpow/64823/ William Finzer and Lillian Ray Use your TI-Nspire and the monthly measurement data for 1958 through 2008 from Mauna Loa to predict the CO2 level for a given month. ***FEATURED TPOW TI-PoW: A Phone-y Deal? http://mathforum.org/mathtools/tpow/64821/ Steve Risberg and Lillian Ray Use your TI-Nspire to compare two cell phone pricing plans and determine which one is the better deal based on call minutes per month. ***FEATURED TPOW TI-PoW: Caliyah's Cart http://mathforum.org/mathtools/tpow/64765/ Lillian Ray Use your TI-Nspire to figure out the maximum number of items Caliyah can buy if she limits the total weight and cost of her purchase. ***FEATURED ACTIVITY Activity: Exploring Linear Programming http://mathforum.org/mathtools/activity/64767/ Lillian Ray A TI-Nspire activity that introduces some of the concepts behind linear programming. It accompanies the TI-PoW Caliyah's Cart.
