Learning high-frequency words (sight words) can be a challenge for some students. By incorporating daily practice for a short period of time, students can commit these often irregular words to memory.
On Mondays, after introducing students' word study pattern for the week, I would also give my students an individualized list of five high-frequency words (worksheet is a word doc so you can modify as you see fit). These words can come from any high-frequency word list you are familiar with, for example, Dolch or Fry. As a general rule, it's best to only introduce a few sight words at a time, because these words tend to be more tricky to remember.
Students know to grab their "My Weekly High-Frequency Words Center Work" double-sided worksheet during center work time, which they will store in their center work folder for the week. At the end of the school day on Thursdays, I'd collect the folders and review their worksheets. (Please note - do check-ins during the week to ensure that your students are correctly spelling their words !)
The worksheet has a short spelling activity for Monday through Thursday. On Thursdays, students find a partner to give them a practice test as their activity for that day.
