Backward design

Backward design is when one sets a main goal in his teaching, and the short term goals reflect that general goal. Meaning that if I set my main goal for the year to make sure my students know the alphabet start blending words and enjoy the reading, I need to make sure that each small goal, each unit, lesson plan, reflects that goal. I need to make sure to keep it exciting so they enjoy it. Make sure they gain their knowledge through exciting ways, so that they can acquire it better and eventually become great readers. Backward design is in essence only focusing on the main goal, when assessing the kids were assessing to see where are they up to,  not on the short term goal, but rather in the long term goal where are they up to. What do I as the teacher need to incorporate into my lesson to reach the ultimate goal.
