Congratulations on finishing the first session of learning sign language numbers from 1 to 10. Now, you can progress to numbers from 11 to 21. Here's a quick summary of the new numbers you will learn:

• For numbers 11 through 15, keep the back of your hand facing the person.
• For numbers 16 through 19, keep your palm facing the person.
• Start with 11 by signing a 1 and wiggling it towards you.
• Proceed to 12 by signing a 2 and wiggling it towards you.
• For 13 to 15, make the sign for the respective numbers and wiggle towards you.
• For 16 to 20, adjust hand direction and wiggle accordingly.
• 21 handshape resembles a gun, saying the number 21.

You can share your learning with your family, friends, or anyone eager to join you in the process. It's fun and fulfilling to teach others. Keep practicing until you feel comfortable with all signs. Great job on your progress!

In your review session, remember to maintain the hand orientation for each number. Test your knowledge by saying the numbers as the signs are made. This practice will solidify your learning. Keep up the fantastic work! Until the next session, continue practicing and improving. Well done!
