App Description

*Now available in ENGLISH and SPANISH*

The hit PBS KIDS show Dinosaur Train welcomes you to the Dinosaur Train Classic in the Jurassic, Jr.!, a unique bilingual app designed to help preschoolers develop and build on valuable math skills as they play with shape puzzles, pan balances, sorting and counting activities.

Track Stars
Use geometric shapes to build train cars, then decorate your train, add passengers, and watch it drive down the track!

Bridge Builder
Help build bridges so the dinosaurs can get around Troodon Town! Drag your finger to measure the distance between two points, then choose the two sets of logs that equal the right length to complete the bridge.

Chow Time
Add food to the scale until it’s balanced to feed the hungry dinosaurs! When you’ve got it right, watch them chow down.

All-Star Sorting
The dinosaurs want to go to their houses! Put the dinosaurs in order by height to get them to the house they belong to.


DINOSAUR TRAIN, produced by The Jim Henson Company, airs weekdays on PBS KIDS (check local listings). The TV series encourages basic scientific thinking skills as the audience learns about life science, natural history and paleontology. The program features Buddy, and adorable preschool age Tyrannosaurus rex, and his adoptive Pteranodon family as they board the Dinosaur Train and embark on whimsical voyages through prehistoric jungles, swamps, volcanoes and oceans.
