-ed/-ing adjectives

Every time we introduce these adjectives in class some students get them confused. The same would happen to english students when they learn the difference between "ser" and "estar" in "ser aburrido", be boring and "estar aburrido".

I introduced these adjectives with an oral activity in which I asjked my students:

Tell me something that you find (add and -ing adjective). 

When the student answers, you can reply, "oh, I see, so (add the adctivity) makes you feel (elicit and -ed adjective)

For instance:

Teacher: Ok, tell me something that you find relaxing

Student: Watching TV /I find watching TV relaxing

Teacher: So, watching TV makes you feel...

Student: ...relaxed

You can try doing it the other way round

Teacher: Ok, tell me something that makes you feel relaxed

Student: Watching TV /Watching TV relaxing makes me feel relaxed

Teacher: So, you find watching TV ... 

Student: ...relaxing
