For Teachers

A whole class, twenty-five different readiness levels, and four minutes before the bell. This is built for that.

Print three versions, hand them out in rows

Check “Print 3 variants” and you get sets A, B and C: identical difficulty, completely different problems, each with its own answer key. Neighbors can’t copy, and a retake next week is never the same page twice.

Differentiate without making three worksheets

Same operation, three ranges — within 10 for your intervention group, within 20 for the class, facts 0–12 for the students who are already flying. Two minutes of clicking instead of an evening of prep.

CCSS on every page

Every sheet is tagged with the standard it practices (K.OA.5, 1.OA.6, 2.OA.2, 3.OA.7), so the page itself is documentation when an administrator asks what the drill is aligned to.

Built for progress monitoring

Keep the format and time limit constant, change only the version, and weekly scores become a clean trend line for RTI folders and data meetings. The worksheet code on each page lets you regenerate the exact same sheet months later.

It works on locked-down school networks

No login, no account, no class codes, no student data collected — nothing to get blocked by a district filter and nothing for you to consent to on your students’ behalf.

Intervention and SPED friendly

Turn on Large Print for bigger type, fewer problems per row and more space to answer — without the babyish clip-art that older struggling students refuse to be seen with.
