In first grade, our school uses Month-by-Month Phonics and Words Their Way. The MBM develops the sight words that they must know in order to read and does some spelling patterns. WTW allows the students to work on patterns at their individual pace.
Here is our word wall routine, day by day...this is when we use the MBM words.
My students work on their WTW sort from a workbook during centers. This way each student is working within their abilities at the given time. The patterns are then reinforced during guided reading groups.
Here are some other items I have posted before but I find really useful while working on words.
