Objectives:
(1) Assess students ability to name ionic compounds using binary monovalent and Stock and common naming systems. (2) Teach flowcharting to enable diagramming of procedures.
Lesson:
(1) Begin with quick assessment of student ability to name binary monovalent ionic compounds and ionic multivalent ionic compounds using Stock & common names. (2) Do "whip around" type assessment for difficulty (I found that I had assessed polyatomic ions but had not taught them - oops!) (3) Students answer B_NarrativeResponse question individually then in group. [It took about 5 minutes before any talking took place, but then they began to look at and ask questions about each other's answers-VERY effective!] (4) Show flowchart presentation of "How to Sharpen a Pencil" and have students copy flowchart example. This gives everyone a common experience to discuss. We learned why different shapes are used and what they mean.
Assignment:
(1) Students make new flowchart having at least one of each shape in it demonstrating "How to eat a banana." Due beginning of next class [next class I will have students write their flowcharts on the board to show similarities ind differences.]
