I will be teaching Kinder starting in August. My school uses the Lucy Calkins kit for teaching writing. I have a general idea of how Kinder writing progresses bt I'm curious about the Lucy Calkins kit. Is it easy to use? Are there any things that you do different? I haven't opened up my kit yet... but is it pretty easy to read and use it day to day? Or is it more theory than actual application? Thank you for any info!
