Zap game I learned in grad school. Put high frequency words on sticks (these are foam sticks) and write zap it on a few sticks. The kids pull sticks from a container and read the words. If someone gets Zap It, all of the sticks go back in the bin.
Structured alphabet sensory table task: magnetic letters hidden in coloured rice with scoops and shovels. Matching letters are stuck onto baking trays (attached to the wall with velcro). Hunt for the letters & stick them onto the corresponding letters.
Kindergarten Sensory Beginning Letter Idea: I like this! Give children a variety of objects and they have to place them with the right letter. You could maybe start off with only one letter and work your way up!
Phonic Baskets Sorting Activity (from The Imagination Tree). Take a few boxes or baskets, write a letter on a piece of paper and gather many different items that begin with the letter. Have the student put the items in the corrected basket/ boxes.
