Does my child need to spell every word correctly?

Not at first. If the word is readable and every sound is there, count it, and write the correct spelling next to it. The answer key on page 2 spells out every word.

Is there room to write a long word like seventeen?

Yes. The sheet prints one card to a row, so each writing line is about four inches long, which fits seventeen in kindergarten-sized letters.

Which numbers are on it?

The default print uses zero to twenty, with a couple of cards from zero to ten. The easier version keeps every card between zero and ten. Each print deals new numbers, and no number shows up twice on a sheet.

How to teach this

Say the number first, then sound out its word together before your child writes it. Most words up to ten can be sounded out, but one, two and eight look nothing like they sound, so those have to be learned by sight. The teens have a pattern: fourteen, sixteen, seventeen and nineteen are the ones word with teen on the end. Thirteen, fifteen and eighteen bend the spelling a little, and eleven and twelve do not follow it at all. Keep a number word chart in view for the first few sheets and let your child copy from it; spelling from memory comes later. Number words go a step past K.CC.A.3, which asks for numerals, so treat this sheet as reading and writing practice that supports it.

Watch for: Kids build every teen by the rule and write fiveteen or threeteen. Put thirteen and fifteen next to three and five and point at the part that changes. Kids spell by sound and write wun, too or ate. Those three words do not look the way they sound, so show them written down and let your child copy each one a few times.
