Oooh that’s similar to one I was taught:

Look around and try identify 5 different objects

Close your eyes and try to identify 4 different sounds

Run your fingers over your clothes and try to identify 3 different textures

Breathe in through your nose and try to identify 2 different smells

Run your tongue around your teeth and try to identify a taste

(Adjust as needed for your body and sense perceptions).
