Here's a fun, active game to play with your kids to help them practice the names of shapes or numbers and colors in Spanish. It can be played indoors or outdoors with different materials.
OUTDOORS: Chalk, and an area with cement.
INDOORS: Colored construction paper and scissors (you can also use colored play foam sheets, which cost more, but last longer).
OUTDOORS: Draw shapes or letters or numbers with various color chalk.
INDOORS: Cut out shapes in various colors and lay them around the room. To practice numbers or letter draw a number or letter on each shape.
To play the game, the parent or leader calls out shape or number or letter or color names in Spanish. The children have to run to the correct shape (or shape in the correct color) and stand or jump on it (for indoors, I suggest telling kids to just touch it with their foot, as the paper gets messed up pretty quick). You can mix it up and draw pictures of other vocabulary you want to cover and practice it in the same way.
