Frequently Asked Questions
What addition skills do kindergarteners learn?
Kindergarteners add within 10 using objects, fingers, and drawings — learning that addition means putting groups together and finding the total.
How do I help a child who counts everything twice?
Teach 'counting on': put the first group in your head and count on from there. For 3 + 4, say '3... 4, 5, 6, 7.'
Are these addition worksheets free and printable?
Yes. Every worksheet is a free, printable PDF with an answer key, and no sign-up is required.
