Many strips are ruled 1½" high with a ¾" dotted midline and a colored baseline (often red) to support handwriting practice.
They’re offered in paper or corrugated paper, laminated cardstock for added durability, and metal/magnetic material for magnetic versions.
You can find plain white strips and assorted color packs — common colors in assorted sets include blue, pink, and yellow.
Magnetic sentence strips are made for magnetic whiteboards, steel lockers, refrigerators, and other magnetic surfaces. Dry-erase strips are write-on/wipe-off and can be used with dry-erase markers or liquid chalk markers.
These strips have a dry-erase surface intended for repeated use; listings note they can be wiped clean after each use for repeated practice.
They’re classroom aids for teaching sentence structure, handwriting and grammar, and for demonstrating writing or practicing penmanship and sentence construction.
