Most teachers use cardstock as a reusable, sequenced lab. Blackline workpages are identical and used when it is more practical for students to write answers on their own paper. Blackline Series Blackline masters for extensions and worksheets offer added options. Extensions are variations of matching, sequencing, and number-line exercises. Instead of manipulating small pieces, students write appropriate responses on their own paper.
Worksheets are blackline masters of the same taskcards offered in the cardstock series.
The blackline series are ideal sequels to the manipulative exercises. They are also valuable when individualized use of cardstock materials is not practical. They are used extensively for diagnostics, whole-class instruction, mastery checks, and homework. Also available are support materials in the form of math facts, place value cards, adddition and multiplication charts, fraction and decimal materials. Inc. All rights reserved.
