Students might not master a lesson concept or may only master a portion of the concept the first time through. We all learn over time so this is not a surprise. It is important to not get stuck teaching the same lesson over and over. Move to the next lesson but keep the skill in mind and provide review daily or during a lesson for example, if the student doesn’t know the numeral 5, make sure to point it out. You can also set up a work station with a para professional to practice with a game or other activity from page 4 of the lesson. You also have the option of going back to a previous lesson for review.
