Pioneer Plaza Cattle Drive
A growing number of bronze, larger-than-life-size steers and their cowboy escorts moo've along Pioneer Plaza - adjacent to the Dallas Convention Center. This bronze cattle drive is located on the actual Shawnee Trail drive of the 1850s - and is the largest bronze monument of its kind in the world.
Downtown, Young & Griffin Streets

Super Model Train
The U.S.' largest permanent model train display is in Dallas, and happily, it.s in the lobby of Children's Medical Center of Dallas. Eight trains run simultaneously at this free exhibit. Children's Medical Center has a small fee for parking.

Other Travel Tips

Go to a Ranger game - Arlington
Go to Six Flags / Wet 'n' Wild - Arlington
There are many nice parks in the area and I hear NRH20 is a nice family water park.
The Dallas Children's Theater
The playroom in the Dallas Museum of Art

Honestly, 1 and 2 year olds are just as happy playing in the backyard inflatable pool!!
Check out guidelive.com. They have everything you can think of including festivals that are in town, plays, shows etc.
I think you mean activities, not "activity's."
There are rides for young children at the fair grounds just east of downtown Dallas. We took our kids there when they were very young.
Dallas Zoo isn't impressive, I agree. (The kids section used to be much better.)

For your two youger kids, I wouldn't suggest any theater. Your four-year-old might like Dallas Children's Theater, and the Dallas Public Libraries have free programs fairly regularly. Some are terrible, some have been great.
