Factor Forge Worksheet

A comprehensive three-packet intervention series for resource math groups covering multi-digit addition algorithms, targeted three-digit subtraction with regrouping, and mixed operational review. Designed with accessible place-value computation frames, clear visual hierarchy, and full teacher answer keys.

A balanced multi-digit computation packet integrating both addition and subtraction algorithms to promote sign discrimination and operational fluency. Contains twenty distinct problems and an annotated teacher key.

Teacher answer key for Mixed Operations with clean place-value alignment (Th, H, T, O), showing red regrouped values floating above place values and final solutions for all 20 problems.

A comprehensive unit covering multi-digit multiplication strategies including visual Area Models and standard Column Grids with regrouping.

Structured three-digit subtraction practice featuring problems with single borrowing, double borrowing across two place values, and regrouping across zeroes. Supported by scaffolded problem frames and a complete key.

A 20-problem mixed addition and subtraction printable packet with clean place-value grid tables (Th, H, T, O) without pre-printed boxes, giving students spacious room for computation.

A comprehensive 5-day unit covering addition, subtraction, multiplication, and division of decimals. Students master standard algorithms, place-value reasoning, and real-world problem solving through scaffolded instruction and rigorous practice.

Targeted multi-digit addition practice focusing on three-digit and four-digit standard algorithms with balanced regrouping levels. Includes a 20-problem student packet with structured place-value workspaces and an answer key.

Teacher answer key for Subtraction Mastery with clean place-value alignment (H, T, O), showing red decomposed values floating directly above place values and differences for all 20 problems.
