Motivate young students to make and break simple three letter words with this set of 12 delightful activity cards. Designed for use with Unifix Letter Cubes, each word ladder requires children to complete a series of words by changing one sound at each step down, reinforcing in concrete terms the effect of swapping one sound for another. Colorful, durable cards are 3½ x 16 inches and teaching notes and answers are included.
