The SPARK Box gives literacy coaches, EIP teachers, and interventionists a hands-on tool for the exact skill Tier 2 and Tier 3 groups target: pulling words apart into individual phonemes and blending them back together. Its guided, multi-axial motion makes the difference between segmenting and blending something students can feel, not just see.
It works as a tactile alternative to flat Elkonin boxes, with constrained grooves that remove the drift and spatial confusion many struggling readers run into.
