Frequently asked questions

How many sight words should a kindergartener know?

By the end of kindergarten, most children are expected to recognize 20-50 sight words. The Dolch pre-primer and primer lists contain 93 words that cover about 50% of all text young children encounter.

What is the difference between Dolch and Fry sight words?

Dolch sight words (220 words) were compiled in 1936 and are organized by grade level. Fry sight words (1,000 words) were updated in 1980 and are organized by frequency. Both lists overlap significantly for kindergarten-level words.

Are free sight words apps as effective as paid ones?

Yes. Apps like SpellingJoy and Khan Academy Kids offer high-quality sight word practice completely free. The key is consistent daily practice of 10-15 minutes, not the price of the app.

How often should my kindergartener practice sight words?

Short, daily sessions of 10-15 minutes are more effective than longer, infrequent sessions. Consistent practice 5 days a week helps move sight words from short-term to long-term memory.

Our Verdict

SpellingJoy is our top pick because it includes both Dolch and Fry sight word lists completely free, with unlimited practice games and progress tracking at no cost.

If you want a broader early learning experience, Khan Academy Kids is an excellent free option that covers sight words alongside math and social-emotional skills.

For families willing to invest in a personalized reading program, HOMER adapts its sight word instruction to each child's level and interests.
