Once upon a time, there were ten little pigs who wanted to cross a river. Let's count them together! One, two, three, four, five, six, seven, eight, nine, ten! Ten little pigs are ready for their adventure.
The little pigs found a small bridge across the river. But there was a warning sign that said 'One at a time!' The bridge was too small and weak to hold more than one pig. So they had to cross one by one, very carefully.
Now watch carefully as the pigs cross the bridge one by one. The first pig steps onto the bridge and walks across slowly. One pig has crossed! Then the second pig crosses safely. Two pigs! Now the third pig is crossing. Three pigs have made it across the river!
Great job counting! Now let's watch as more pigs cross the bridge. The fourth pig crosses carefully. Four! The fifth pig steps across. Five! The sixth pig makes it safely. Six! And now the seventh pig is crossing. Seven pigs have crossed the river! Only three more pigs are waiting to cross.
