Sample problem Sandy’s family does its laundry at a coin-operated laundromat. It costs $1.25 per load to use the washing machine and 25 cents per load to use the dryers for 10 minutes. Sandy’s family has 5 loads of laundry to do and each load will need to be in a dryer for 30 minutes. Which expression will give Sandy’s family the total cost of doing these loads of laundry? A. ($1.25 + $0.25) x 3 x 5 B. [$1.25 + (3 x $0.25)] x 5 C. [(3 x $1.25) + $0.25] x 5 D. 3 x ($1.25 + $ 0.25) x 5
A framework for planning and reflecting on Mathematics Instruction A)Academic content 1.How experienced are students with mathematics concepts and procedures? 2.How experienced are students with concepts from other content areas? B) Mathematical and cognitive processes 1.What mathematical processes are needed and how experienced are they using them? 2.What cognitive processing skills are needed? C) Mathematical and Contextual Language 1.Do students prior experiences include the development of mathematical language? 2.Do words that have specialized meanings in mathematics have different meanings in natural language? D) Cultural/Life Experiences 1.What knowledge of cultural or life experiences is needed to understand the problem statement? 2.What connections need to be made between the mathematics of the classroom and student experience?
