Hello, my DS brought home yesterday an ORT Stage 11 treetops fiction book. On the back, it says "KS1 Book Band 10 white/ KS2 book Band Y3 brown" Can anyone explain to me how the same book could be for KS1 and KS2 at the same time? Are the different Key Stages looking for different things from the kids reading the same book? Does Y3 stand for year 3? He's currently in Yr 2. I'm
! TIA!
