Teaching "eso" and "esto" mnemonic

Question

When teaching demonstrative adjectives, it’s always difficult for the learner to remember which is which between “eso” and “esto”. I finally had success when I gave the students the following mnemonic.

I always had a big glass of tea with me when I was teaching. All I had to do was tell them the tea (t) was always near me. Once they had a visual, they could remember “esto” was this. I no longer drink tea that way, but when we practice these, I’ll keep a bottle of tea with me during the class.

Answer 1

I always remembered it because esto has a 't' and that is the first letter of 'touch' which I can always do with 'esTo' (this) but not with 'eso' (that).

I bet your students will never forget that lesson. Makes me want some ice tea right now.
