I take a break from offering a 'program' in the summer

We spend most of our time at parks, local outings and field trips and in the afternoon in the yard keeping cool....my backyard has all the same 'staple' materials as inside program wise so if they want to curl up under a tree with some books they can, if they want to build we have outside blocks and so forth

I have found that after a year in school most school agers just want to PLAY so being outside allows them to run off steam at parks, splash pads, hiking for nature treasures to bring back to the yard to either create a 3D art project with or just explore further. If it is yucky outside than we head on a field trip to a museum or other indoor adventure for them to explore.

I do not plan 'crafts' for them either, outside of special occasions where a gift for the parent is traditionally offered, so like any other time of the year I just set out open ended mediums that they can use as they see fit but that an 'infant' can also explore based on their development ... so the school agers might be building something with 3D materials and glue and tape and the infant might be sitting in their booster exploring just the 'tape' and how it feels and sticks.
