Instead of TELLING your child the words, ask him to choose!

Use Felt Boards, dolls, clothing, even blocks, or Matchbox cars, and ask him:

     Quieres el carro rojo o azul? (Do you want the red car, or blue?)

     Tienes el juguete nuevo o viejo? (Do you have the old toy, or the new one?)

Point or touch the item as you describe it, and if your son or daughter doesn't respond in Spanish, that's okay! Say, "Oh, tienes el carro rojo. Muy bien."

A helpful supplement is:Flip Flop Felt Friends - which comes with an instruction pamphlet to use and play with in ANY language! - Sra. Gose uses this with her students from ages 3 to 46 (that's the age of my eldest student right now) , and the set has lasted for more than four years in weekly classes, four hours a day. VERY durable!
