This Mastery Method, which correlates to the Common Core, is made up of two parts, the flash cards and the manual, which may be purchased separately. You may choose to follow the complete program or just check out the tricks for those particular facts that give your students the most difficulty.
Part B is the step-by-step comprehensive MANUAL, which explains how to introduce, practice, and test each set of facts. The manual not only EXPLAINS EACH RULE AND TRICK, but it will instruct even a new teacher to lead their entire class to MASTERY of all of the facts. It includes an appendix of extras including differentiation strategies, parent letters, quiz sheets, check-up slips, and monthly progress reports.
Part A is the printable flash cards themselves. What makes them UNIQUE is that they have the TRICKS, RULES, PICTURES, and ANSWERS ON THE BACKS. If the children get one wrong when they are practicing with this set, they receive immediate reminders of the trick for that fact. The flash cards are easy to run off back-to-back, and the students can cut simply them on the lines.
