Open any sheet and choose Download PDF — it is already laid out on a standard page with margins, so it prints without cropping. If you would rather resize it or use it on a screen, take the PNG instead. Every sheet is pure line art on white, so it costs almost nothing in ink.
The same care that goes into these sheets goes into our read-aloud books: every word highlighted as it is spoken, so your child follows along and starts reading on their own.
