What's the best way to add a spontaneous lesson into the lesson plans? Like, if we have science planned out for the semester and entered in to Olly, but then we have a spontaneous lesson that wasn't originally planned but now want to enter it into Olly. Do you just add it into the end of the sequence for that subject? Or do you sequence your lessons with spaced out (like number the sequence by twos instead of by ones) so that you can enter in something random that you end up doing? This is what I am thinking about doing, but looking for ideas on what others do.
