When you do a theme, how long do you spend on it per day? I was thinking about themes, but I just can't justify spending an entire month on the shape of a heart. Repitition is very important but I tend to do the core shapes a few times per week and then add a more complex shape in per week to 'study' We all have children at different levels. If a few children have learned the 'heart' and others haven't, what do you do with the children that are more advanced for the rest of the month?
