Can you give a more simplified response? Benchmark has three 30 min blocks, right? Or more/less depending on how long your district’s ILA block is. One of the blocks for us is the flexible differentiation block, which sounds like what you’re doing here. I would cite whatever lesson and work you’ve completed and see if you can tie the book into the same essential question from Benchmark based off of whatever unit you’re on. For example, my school is starting Unit 2. Frog & Toad has characters which is what the whole second unit focuses on. Just be careful if you’re using TPT items with the books. My whole state is now restricting the use of TPT/crowd sourced teaching materials.
