I start with explain lessons to children and solve the examples of that lessons so they understand the aim of lesson what it's for. we discuss about problem i give to them and children try to solve by themselves. I'll show them some videos and shapes if it necessary. I have to completely sure they get the details of etimes i teach them some tricks and play with sounds and songs. for every lesson maybe we have different plans and we try to use some kind of material to make sure they know the lessons now. After that children can question about anything and solve their doubt about the topic we work. Finally we had a quiz so we can figure out what's the problem with them.
