Children practice blending phonemes...and build 50 different CVC words! Our center is packed with tons of activity cards and easy-grip foam letters that let kids build words at 2 levels: Beginners match letter to letter to form words step by step...while advancing children flip the cards over, filling in the missing letter to spell each word on their own! 150 color-coded letters and 50 two-sided activity cards, in a 10 1/2" cardboard center.
