Number Blends for Time and Age
ASL can blend numbers into some time and age signs, so a phrase like THREE-WEEK can become one smooth sign.

Learn It
Start with the simple version, then practice it with real signs.
Some ASL signs can carry a number inside the sign. This is called numeral incorporation, but you can think of it as a number blend.
For common time ideas like WEEK, MONTH, DAY, HOUR, and age, numbers 1 through 9 can often blend into the movement.
For 10 or higher, keep it clear and sign the number and the time or age sign separately.
Try It
Practice slowly. Make the face before the sentence is over.
- Practice WEEK with a 1 handshape, then change only the handshape to 2, 3, and 4 while the movement stays the same.
- Practice MONTH by sliding a number handshape down your other index finger.
- Sign BABY FIVE-MONTH OLD. Make FIVE-MONTH one smooth sign, then add OLD or point back to the baby.
Simple Examples
Read the ASL line first, then check the meaning and tip.
THREE-WEEK LATE ME.BABY FIVE-MONTH OLD.ME AGE-8.Common Mistake
Do not force every number into a sign. If the number is 10 or higher, or the blend feels unclear, sign it separately.
A little more grammar
This is often called the Rule of 9. The number handshape changes, but the base sign keeps its normal place and movement so the viewer can still read it quickly.
