This idea comes from Janet Holzer on the moreTPRS list and it is excellent! This reading activity starts with the teacher reading the story aloud in the target language while students write “problem words” that they do not understand (major words only, not “a” or “the”) on sticky notes. Janet defines a “problem word” as a word students don’t know that keeps them from understanding the whole sentence. After you have read a section aloud for about 5 minutes, have students stop and translate for five minutes with a partner while comparing sticky notes. Tell them to use a noise or a filler word (ie. “something”, “blank”) for unknown words. Then they should try to guess the unknown words. After the initial reading, have them switch partners once or twice and do the same thing. After each rotation of partners, ask them to do a 10-finger comprehension check to show you how much they understand. Then after they have finished, ask kids to volunteer the translations for words that they had trouble with but figured out (this helps the kids who didn’t figure out those words).
