Lesson:
1. First thing, please give these students a "trial" test. Have them treat this as a real test (put all books away, sit separately, etc.) When all students are gone have students take turns offering correct answers and compare them to the key (see hard copy). Where this is disagreement among students about the right answer, encourage them to talk and reach a consensus. The students are doing well and can help each other successfully with this difficult material.
2. Students have a list of vocabulary words: jigsaw, bonding, covalent, electrostatic, pooling, monatomic, polyatomic, monovalent, net charge, cation, anion, ionic compound, valence. Students should finish making definitions for each of the words or terms. Their vocabulary paper-which they should already have-needs to have three columns: word in English, same word or synonym in Korean, definition in English.
3. Students should make a crossword of their terms. It should look like a normal crossword puzzle-see attached example. The crossword should be made on paper and should include definitions, numbered clues, boxes for letters and so on. Students to not need to cut-off words like we have done in tests; they can use the whole word in this assignment (see example). Students may use 1 cm graph paper for their puzzle and cut out the pattern they need or they can make the whole thing on paper with a pencil and a ruler. Please do not let them do this on the computer (they stay focussed better when working on paper.)
