My daughter found it hard to blend sounds into words. The “easy” books she was given were full of words she had not been taught to sound out, so she guessed. I built a free reading app for her that only uses the letter-sounds she already knew, and it worked well for her. The app is now part of this site and is free for every child: open the free reading app.
These printables grew from that. The reading pages only use words a beginner can sound out, and every word is checked. The tracing, counting and math pages follow the same idea: one clear activity at a time, so a young child can do the page without help.
