Goal:
You have already met 15's younger siblings, 13 and 14.

Now, you get to meet the number 15. 
Like 13 and 14, 15 is in the Teen family. Just like family members who have the same last name, the Teen family shares parts of its name: Their numbers start with 1, and their number words end in teen. Look at the first three members of the Teen family. How can you tell which number is 15? 
Yes! 15 has a 5 as its second number. Find 15 on this number line. Then, count from 1 to 15. 
Terrific! Next, you'll see 15 and its younger siblings shown a different way. |
