Drag-n-match games help children learn vocabulary, by matching a word or phrase with its Spanish equivalent. Children can play on-line, or more traditionally. With the latter, you have the word or phrase on one side of a sheet of paper and the Spanish translations on the opposite side, leaving children to draw arrows matching up the correct pairs. You could provide accompanying visuals on the paper to help stimulate a child's interest.
Along the same lines, memory match games help children remember Spanish words and phrases. Like drag-n-match, children can play at an on-line game site, or with a set of playing cards (which you may have to draft yourself if you don't have a set of Spanish cards). With the cards turned face down, children turn one card over and proceed to flip over another, hoping to find its match. If multiple children are playing, they take turns flipping cards over, until one finds a match. If the child finds a match, he or she continues searching for more matches.
Another visual game that helps children with their language and vocabulary retention is identification. For example, have a picture showing various animals, and from a list (in Spanish), have children check or circle the ones that appear in the picture. Again, you can choose whichever theme you would like, such as foods or parts of your face or body.
Crossword puzzles also offer a challenging avenue for children to learn Spanish. Remember that the kids are novice Spanish speakers, so it's best to have the clues in English, at least at the beginning. Perhaps later on you can introduce an all-Spanish crossword puzzle.
Word searches also help children retain vocabulary. Rather than jumbling together random Spanish words, have the words tied to a specific theme - for example, things you find around the house. That way, children are thinking of the items in English and, in turn, translating them to their Spanish equivalents within the puzzle.
Listening quizzes can provide children with a good mix of enjoyment and learning. Say a word or phrase in Spanish, and have children choose the English translation (or vice versa) from a group of two or three possible answers. If you don't want to play moderator, find an on-line version of the game for the children to play.
Music may often serve as recreation, but it also can be an educational tool for learning Spanish, whatever the learning theme (the alphabet, days of the week, colors, holiday-related songs). Take the children's song "Ten Little Indians." If a child is learning to count in Spanish, replace Indians with something cute like puppies. Rather than "one little, two little, three little Indians," the new version would go, "Uno dos tres perritos..." Once a child's learning reaches more advanced levels, either provide a Spanish translation of a popular song, or have them translate the song into Spanish, to the best of their abilities.
