Like most households, we have lots of Lego and both my boy and girl love to construct things. Most of the time, I will just let my children be creative with Lego and create whatever they fancy. However, sometimes I will give them an object to create or a theme to follow. I have set different theme/objects over the years: build your dream house, invent a new animal, create a flying machine, anything linked to space etc.
The dream house always seems to have an outdoor swimming pool and the new animal is always a mixed of two or more animals. I have set Islamic themes too. I ask the children to create a Mosque.
Before they set out building their Mosque, we looked at different areas in a Mosque. We used Hassan and Aneesa Go to Masjid book which was brilliant for explaining the purpose and the features in a Mosque.
