Math to Mastery is a teacher-directed instructional practice in which students are individually administering the intervention in an attempt to master particular skills/math problems.

How To

1. Determine the skill(s) used for the intervention according to CBA or computer adapted assessments.  The earliest unmastered pre-requisite skills in the sequence for the math operation should be targeted first.

2. Demonstrate how to complete each math problem on a worksheet whilst the student follows along on his/her copy.

3. Student practices the problems on the worksheet in one-minute trials until mastery (32 DCPM) is attained or ten one-minute trials are completed.

4. Follow along while student is working marking errors and giving immediate corrective feedback.

5. After each one-minute trial, compute the digits correct and errors; offer a great deal of specific praise for effort and performance.

6. Student charts his/her performance at the end of each 1-minute trial.

7. At the end of each session (or at least once weekly), student is administered a brief assessment (e.g., CBA), which is completed individually and scored to monitor progress on the target skill.

8. Once every other week (or monthly), a multiple skill CBM probe is administered to progress monitor for generalization.

Available Training

Utilizing the manual to administer the process (available in Doggett et al., 2006) would be useful.  Training may be needed on using CBA to determine the targeted skill(s) for the intervention.
