To memorize the irregulars, remember last words, like -é, -emos, <span>-éis, -án. Connect normal irregulars with these words. Boom, you make a future tense irregular.
Estar+emos=estaremos
Vivir+é=viviré</span>
It depends, what is on the list? If "playing, dancing, or singing " is on there than here you go:
-Angel and Lupita are playing.
-Angel and Lupita are dancing.
-Angel and Lupita are singing.
