Alphabet Walk

Make binoculars with your children out of toilet paper rolls or paper towel rolls. Cover them with construction paper and decorate them with markers, crayons, sticker, etc. Hole punch two holes (one on each side of the binoculars) and tie a string to go around their necks. Then take them on a walk around the neighborhood and look for letters on signs, houses, license plates, cars, etc. Have the children call out the letters they see and try to sound out the words. You could also do this same thing with shapes, colors, or numbers.

Musical Flowers

Make flowers out of construction paper and laminate them. Make one for every child in your class plus a few extra (just in case). I made my flowers different colors and put # in the center of them. You could put shapes on them too if you wish. Then you put on some music (something to do with spring or plants or gardens would be fun) and have then children walk around the flowers. Then when the music stops, you call out a number, shape or color (adjust to their age/ability). The child standing near that flower holds it up and then they get to choose a treat/sticker and then be your helper and watch the other children until the activity is over. This is great because you can ask your 2 year old what color their flowers is, your 3 year old what shape they have, and your 4 year old the number. It is quickly and easily changed to fit every age.

Little Mouse

When teaching colors to your children this is a fun game. You make houses of different colors and a mouse that is small enough to hide behind them. You take turns with the children and have one close their eyes or leave the room and show the others which color house you are going to hide the mouse behind. The child comes back into the room and chooses a color (without touching them). You say, "Little mouse, little mouse are you in the ______ house?" You let the child look behind that color house AFTER you have finished the rhyme. Go through all of the colors until you find the mouse.
Another variation of this game is with bees and trees. Make the treetops different colors and say, "Little bee, little bee, are you in the _____ tree?" Obviously the options are endless with other animals/objects. Be creative!
