Cover Copy Compare is a general strategy for building fluency with math facts or other math skills (e.g., numeral identification). When applying this strategy to math, a student (a) looks at a correctly-answered problem, (b) covers the problems with a card or bookmark, (c) copies the entire problem, and (d) uncovers the original problem and compares the written work to the original.

A typical Cover Copy Compare worksheet involves 8-10 problems that are related (e.g., all division facts with 7 as the divisor). Students work individually on Cover Copy Compare, so teachers can use the practice in whole-class, small-group, or individual settings. Cover Copy Compare worksheets can be created by any teachers for any math skill that requires building fluency. There is no formal program to purchase. Some versions of the Copy Cover Compare method recommend that the student (a) copy a correctly-answered problem, (b) cover both, (c) write the problem from memory, and (d) compare the version from memory to the other two problems.

Cover Copy Compare is intended for use in grades K-12. It is designed for use with any student at risk of academic failure. The academic area of focus is math, with particular emphasis on computation, whole number arithmetic, fractions, and numbers and decimals (rational number).

Many research and practitioner articles have been published that discuss using Cover Copy Compare (or Copy Cover Compare) to increase math fluency. For early research on Cover Copy Compare, see Skinner, Turco, Beatty, and Rasavage (1989).

Cover Copy Compare is a non-commercial intervention and, therefore, does not have a formal pricing plan.

Copy Cover Compare is designed for students working individually, though instructors may engage small or large groups in the activity.

Copy Cover Compare is administered for 5-10 minutes per session. 5 sessions are recommended per week until fluency is established.

No technology is required.

A school staff person at any level can provide instruction on Cover Copy Compare. For implementation, instructors must be familiar with the Cover Copy Compare procedure and teach the procedure to students. The program does not assume that the instructor has expertise in a given area.

Design: Convincing Evidence

Does the study include three data points or sufficient number to document a stable performance within that phase? No

Is there opportunity for at least three demonstrations of experimental control? Yes

If the study is an alternating treatment design, are there five repetitions of the alternating sequence? Yes

If the study is a multiple baseline, is it concurrent? Not applicable

Fidelity of Implementation: Convincing Evidence

Describe when and how fidelity of treatment information was obtained: A checklist was used to ensure fidelity for 37% of sessions for Benson, 40% of sessions for Mary, and 42% of sessions for Greta. 

Provide documentation (i.e., in terms of numbers) of fidelity of treatment implementation: Procedural fidelity was 100% for Benson and 99% for both Mary and Greta.

Targeted  Measure Reliability Statistics Relevance to Program Focus Exposure to Related Content Among Control Group

Curriculum-based measurement (CBM)

Measures were developed by the researchers; they report test-retest and validity coefficients, but the data are not for the CBM probe they developed.

Problems were identified as areas for improvement by the teacher and matched for each student’s level of instruction.
