Drilling the TWO-to-THREE Hooks
2010 June 25
778 of the 1015 three-letter words can be formed by adding a letter to a two-letter word. Specifically, 528 words can be formed by adding a letter to the left (or front), and 539 words can be formed by adding a letter to the right (or back). Eliminating duplicates yields 778 unique words (i.e. some three-letter words can be formed either way, e.g. HOS can be formed by either adding an H to OS, or adding an S to HO).
The grids I’ve attached below are designed for drilling these 778 three-letter words:
1) Grid — Filled In: THREES Hook Grid FILLED
2) Grid — Blank (with counts): THREES Hook Grid BLANK
3) Grid — Bank (without counts): THREES Hook Grid GRID ONLY
