it takes some planning beforehand..
I have been using supper & bedtime for past couple of weeks to pretend to my children that they are in mitzrayim.. and acting different parts out in story version. I even told them my own version of the story Dual Discovery.. (great book)
Read Let my nation Go! by Yosef? Deutch.. it gets your imagination going!
you can buy kits for the Makos.. or make your own.. Oriental Trading has good stuff.
I know someone that even had his lights timed to go off for 15 mins for Makos Choshech! it wasn’t always perfect from 1 night to the next.. but it was fun.. especially as it surpried everyone!
Give ‘parts’ out to family members to act out..
Focus on the timeline.. from Avraham.. through history.. so kids can relate.. that this is US.
My kids know that Seder is time for Tatty to talk and answer.. all the divrei torah they learn in schol – there are 8 other seuda’s to say them at.
