You can get season tickets to Dallas Children's Theater (two seats for each of four plays) on Groupon right now for just $72 total. (That makes each ticket $9) That's a steal. This one will sell out fast at this price and there is only a limited quantity available, so scoop it up. You can also choose to just buy 2 tickets to any play for just $24, which is also a steal.
We have had Dallas Children's Theater season tickets for 13 years at my house, and both my kids have enjoyed their summer camps and workshops as well. They are an excellent and affordable way to introduce your children to theater.
