First we had Bonfire Night: "Remember remember the fifth of November..." - so we read a lovely little book on the Gunpowder Plot together, simple enough to hold all the children's interest, but detailed enough to explain a bit of the background, then they all drew a related picture. My 10 year old niece was also visiting - she is also home educated now, and my sister was working, so she joined in with what we were doing...
Niece's "Bonfire Night"
Youngest's "Queen Mary" (explaining the reason behind the plotting)
For both topics we really appreciated the opportunity to use a 'starting point' resource, whether a book, website or other idea, and then springboard off that with naturally occurring questions, leading to further activities wherever our interest leads. It's a really natural style of home education that suits us most, and I love it!
