Flash Card Directions– Please use the provided flashcards to memorize some of the important

vocabulary in this unit.– Write answer word (1st column) on the back of all of the flashcards in

that row. Then cut the flash cards out and try to line up the three boxes to complete each important vocabulary word with its name, meaning, and picture.

– Start small with only a few, get really good at those, and then add more into your practice. Each time you master a small set by lining up all three add another in until they are all mastered.

– Moving the cards around on a table / clean surface is how these will help you. Just staring at them / trying to memorize them without moving and jumbling will not be as helpful.
