A comprehensive 45-minute structured small group lesson designed for special education students to master the make-a-ten addition strategy. Students use hands-on double ten frames and counter manipulation to decompose single-digit numbers, fill a complete ten-frame, and bridge from the original addition equation to a friendly 10-plus fact.

A large-print, print-ready special education math worksheet for counting 3D wooden geoblock structures from 1 to 10 with write-in boxes and number choice options.

A comprehensive multi-day geometry sequence covering angle relationships, formal two-column, flowchart, and paragraph proofs, converses, and auxiliary line applications for parallel lines cut by transversals.

Kindergarten investigations lessons on classifying objects by attributes. Students identify shared attributes among mixed blocks and sort collections by size and color.

A student-facing exit ticket worksheet designed for special education learners. Features 3 scaffolded problems with visual double ten-frames, explicit 2nd addend number-bond decomposition prompts, bite-size step cues, and dedicated handwriting lines for both the 10+ friendly number sentence and original addition sentence.
