We're having a lot of fun with our train themed preschool activities this month. Trains are a great tool to help teach young boys about sequencing things correctly. We also did fun alphabet train activities that used these same methods. You could apply this idea to other things you want them to learn in a sequential order as well.
Ten Commandments or Numbers Train
Ten commandments train printed out and cut apart (or numbers written on flashcards and an picture of an engine)
Have the child arrange the numbers in the correct order; offer help as needed. Once they get all of the numbers in the correct order, they can put the engine at the end to pull the train!
