Ringo atelier is a creative studio, and resource, for children and their blog is lovely, too. Lots of their drawing activities have a PDF to print out and do at home. They have loads of pages to colour and develop, like this invent the fruit that goes with this leaf (below; above is Auggie's rainbow fruit), which we tried yesterday during a rainy day
and this construct a city (this one is meant to be for collage, but we painted and scribbled them)
There are also some really great projects that we haven't yet tried, like the à la manière de section, with projects inspired by the work of artists like David Hockney or Sonia Delaunay. I think the David Hockney one is perfect for July, and I will put in a little translation here (find the original project here). Observe water (in your bath, swimming pool, by the sea or edge of a lake...), in the style of painter David Hockney. Have fun trying to reproduce the waves, the reflections, the colour of the water. To do this, use watered-down paint, sponges, tissues and different papers. Look carefully at this painting of a swimming pool (below, left)
The 1 livre—1 book section has a nice library of books, too.
