Print out the vocabulary words your child is supposed to learn, as well as the definition of each word and a scene that depicts each word's meaning. For example, for the word vocabulary word happy, print out "Happy: to feel joy," and include a photo of your child smiling.
Post the vocabulary words, their definitions and the scene that describes each word's meaning in a prominent location your child will view every day. This might be on the refrigerator door, on your child's bedroom wall or on the bathroom mirror.
Go over your child's vocabulary list and find a way to incorporate the words in casual conversation. Help your child memorize the words through context clues. For example, if one of your child's vocabulary words is "similar," rather than saying "You and your sister's dresses look almost exactly alike"; say "You and your sister's dresses are similar."
Help your child study for the quiz at least a week in advance, so that your child doesn't have to cram or feel stressed about learning the material. Every night, go over the list of words twice. The first time, say the word and have your child spell the word and tell you the definition. The second time, say the definition and have our child say and spell the appropriate word. Mix the match the order so your child doesn't memorize the list, but actually learns it.
Read books often with your child and point out the vocabulary words she's learning so she can see how they're used in everyday life. Emphasize situations where her vocabulary words apply. For the word "excursion," for example, if you're discussing with your child how her father and his friends went to play golf and then went to get something to eat, say, "Which one of your vocabulary words match what your dad and his friends did today?"
