my teacher is so confusing

So my teacher yesterday posted work that we needed to do for the next day and that's fine but apparently it was work we needed to do over the 2 weeks of. We have already had our 2 weeks of he did not tell us about any of this until last night and I didn't know about any of it till this morning. Thankfully he knows we have other projects so he is a bit more Leenient but still why say we have work for the 2 weeks after the 2 weeks is up ꒰ ᐢ ◞‸◟ᐢ꒱
