Fully revised student workbook with extreme focus on vertical spacing and large decoding targets. Replaced cramped 3-4 word grids with 2-word vertical stacks to provide maximum handwriting room. Fonts for word division targets increased to 5xl/6xl. Handwriting boxes expanded to 24mm height. Simplified activity content (e.g., Radar Match reduced to 2 pairs) to ensure nothing is cut off and everything is perfectly readable at high contrast.
