How to write 13
Thirteen is a 1 and a 3. The 3 has two bumps; keep them the same size and make sure both touch the guide lines.
Number facts for thirteen
One more than thirteen is 14, and one less is 12. 13 is odd, so 13 socks make 6 pairs with one left over. You can make thirteen as 12 + 1, 11 + 2, 10 + 3 or 9 + 4. It is one ten and 3 ones: a full ten-frame and 3 more. Count on from 13: 14, 15, 16. Count back: 12, 11, 10.
Thirteen in real life
In the teen numbers the ones digit is said first: "thir-teen" means three and ten. Show 13 with a full ten frame and three extra counters, and say "ten and three."

A solid 13 with a numbered arrow comes first, then dotted copies, the word "thirteen" and an empty row to write alone. When it feels easy, try 14.
