Help:How To Use the Lesson Numbers Listed in Strands
From FreeReading
A Note on Lesson Deltas. If you're using an integrated instructional program such as IPID 101 that comes with a map, follow the lesson numbers in the map and ignore the deltas below. If you're using this sequence outside of a program map (e.g., you're creating your own program), take whatever lesson number you are at when you start this sequence, call that Lesson N, and add the deltas below to N to calculate the lesson number for each subsequent lesson -- i.e., if you are on Lesson 10 when you start this sequence, then the activities below labeled +14 should be included in your Lesson 24.
