You might think that looking for SpongeBob Squarepants coloring pages is going to be something that will take you all afternoon, or all day depending on your particular point-of-view. However, you are going to find that there are websites out there that cater to this, and many other whims like this, that ca be found pretty easily with a few simple mouse clicks. If you have a few hours to kill to look for this stuff, that is pretty good. However, if you only have about an hour, or maybe less, you are going to be able to find what you are looking for relatively quickly when you are very specific about your search terms. Anyone that has very young children automatically knows that there really are not enough hours in the day to do what you really need to do, much less what you want to do that is recreational.
Whether you are a preschool teacher or a parent, you will only be all too aware of the need to keep your children constantly occupied and amused, otherwise they will get restless, agitated and irritable. Trying to do find an activity that will sustain their interest for any reasonable length of time as well as one that will not actually pose any level of risk or danger to the child can be a task easier said than done. Contrary to what you may think, children are not involved in a mass conspiracy designed specifically to make your life as difficult as possible, rather, they lack the emotional and intellectual maturity to appreciate that certain activities are wrong, or are "naughty" because they are dangerous.
Kids love dinosaurs and kids love crayons, pencils and painting. So coloring dinosaur pictures makes a great activity for toddlers, preschoolers and older kids. There are lots of free dino coloring pages available on the web, but the quality varies considerably. If you know where to look, you can get straight to coloring a T-Rex or a Pteranodon without spending lots of time searching.
