Remember that kids put more attention on animation. They are more interested on having fun so it is best for a teacher to teach them write letters in a fun way. Teachers may have noticed that when children are just being told on what to do, they may not do it right out of lack of interest. Remember that with the so many worksheets available, choose one that is best suited for a certain lesson. Plan ahead what type of worksheet to use for a given day, depending on what you plan to teach.
There are many kinds of worksheets available but the best one is still the personally drafted one. This way one can easily check the level of difficulty that is offered to the kids according to their age and even check the progress level. Worksheets can be reused but it is always better to upgrade them from time to time.
