Missing Link Math

A comprehensive 10-day remedial sequence targeting standard 1.OA.4 (understanding subtraction as an unknown-addend problem) for first-grade students. The unit leverages highly structured ten-frames, part-part-whole visual organizers, fine-motor cut-and-paste sorting, and station-based independent task cards to move students from concrete modeling to abstract math reasoning.

A scaffolded addition packet (1-10) for early learners requiring large print, tracing support, and high-contrast animal visuals, accompanied by an instructional teacher guide.

A cohesive 2-page home-study assignment mirroring the scaffolded lessons: Page 1 features 5 high-contrast animal counting problems with a 1-10 number line, and Page 2 features 3 count-and-add combining problems with oversized writing boxes.

An introduction to the US Standard Algorithm for 3-digit whole number addition without regrouping. Features place value charts (Hundreds, Tens, Ones) for drawing disks, followed by grid-scaffolded algorithm problems to support clean digit alignment.

A 2-page addition exit ticket to assess early learners' mastery of the three scaffolding levels: counting animal groups, writing addition equations from count blocks, and drawing dots to solve. Features standard, oversized answer boxes and dot symbol helpers.

Provides a single-page highly simple, easy-to-use teacher guide explaining how to roll out the student packet and coordinate the games.
