Which Letter? Worksheets
BrainRotU gives the child a printable that shows a picture and a row of letters and asks them to circle the letter the picture STARTS with — the reverse of beginning sounds, mapping the object's first sound back to its letter.
Sample sheets
Shown on ocean — and any other theme your child loves.

Ocean Sounds — Which Letter? (5–6)
Circle the letter that matches the beginning sound of each ocean-themed picture.
How it adapts to your child
Every which letter? sheet is generated fresh for your child, not pulled from a fixed set. As they master the level, BrainRotU's adaptive leveling nudges the difficulty up a band; if a sheet comes back too hard, it eases back down — so the worksheet keeps meeting them where they are. Snap a photo when they finish and it grades itself.
