How to write 17
Seventeen is a 1 and a 7. The 7 is one stroke: across the top, then a slant down. Keep the slant straight so it does not curl.
Number facts for seventeen
One more than seventeen is 18, and one less is 16. 17 is odd, so 17 socks make 8 pairs with one left over. You can make seventeen as 16 + 1, 15 + 2, 14 + 3 or 13 + 4. It is one ten and 7 ones: a full ten-frame and 7 more. Count on from 17: 18, 19, 20. Count back: 16, 15, 14.
Seventeen in real life
Build seventeen with a full ten frame and seven more counters. Ask: "How many more to make twenty?" Count on together from seventeen: 18, 19, 20.

A solid 17 with a numbered arrow comes first, then dotted copies, the word "seventeen" and an empty row to write alone. When it feels easy, try 18.
