## About the Resource
The **Triangle Congruence Proofs Differentiated Task Cards Bundle** is a ready-to-use **High School Geometry resource for Grades 9–10** designed to help students build confidence with **triangle congruence proofs, two-column proofs, geometric reasoning, and proof writing**.
The differentiated progression moves from supported reasoning to independent proof construction across **SSS, SAS, ASA, AAS, and HL**, with visual diagrams, proof organizers, sentence stems, and a modified version for students who benefit from additional scaffolding.
Product description
⭐ **BACK-TO-SCHOOL BUNDLE PRICING — Save 20% for the first 48 hours!** ⭐
Differentiate triangle congruence proofs in a single class period—without writing three separate curricula. This **90-page scaffolded bundle** moves students from fill-in-the-reason proofs to full two-column proofs, with explicit visual supports built in for Special Education and IEP learners.

### **WHAT MAKES THIS RESOURCE DIFFERENT**
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✓ **THREE TIERS** of 12 cards each (**36 total**) — students progress from fill-in-the-reason → fill-in-the-statement → full proofs from scratch
✓ **SpEd MODIFIED VERSION** — 4 proofs with enlarged diagrams, color-coded parts, and printed sentence stems
✓ **SELF-CHECKING SCAVENGER HUNT** — 8 cards that loop around the room with immediate feedback
✓ **PROOF-OUTLINE ORGANIZER** on every Tier A card — a visual Given → Identify → Choose → Conclude frame
✓ **COLOR-CODED DIAGRAMS** — red, blue, and green tick marks for corresponding parts, also legible in black and white through single/double/triple tick counts
✓ **SENTENCE STEMS** for reasoning — “Since ___ congruent to ___ by ___, we can conclude ___”
✓ **DETAILED LUCID SOLUTIONS** — every proof includes a “Why this works” explanation in teacher- and student-friendly language

### **TEACHER SUPPORT (Pages 4–11)**
• Teacher Notes with 4 differentiated usage options and a pacing guide • Special Education Supports & Differentiation Matrix • Triangle Congruence Concept Refresher — SSS, SAS, ASA, AAS, HL • Proof-Writing Toolkit with sentence stems and a complete reason bank
### **TIER A — FILL-IN-THE-REASON**
**12 task cards + 12 solutions**
Students receive the statements and supply reasons from a word bank.
Each card includes a **4-step proof-outline visual organizer**.
**Cards 1–3:** SSS **Cards 4–6:** SAS **Cards 7–9:** ASA/AAS **Cards 10–12:** HL
### **TIER B — FILL-IN-THE-STATEMENT**
**12 task cards + 12 solutions**
Students receive the reasons and supply statements by reading the color-coded diagram.
**Cards 13–15:** SSS **Cards 16–18:** SAS **Cards 19–21:** ASA/AAS **Cards 22–24:** HL
### **TIER C — FULL PROOFS FROM SCRATCH**
**12 task cards + 12 solutions**
Students receive the diagram only and construct the complete two-column proof.
**Cards 25–27:** SSS **Cards 28–30:** SAS **Cards 31–33:** ASA/AAS **Cards 34–36:** HL
### **SELF-CHECKING SCAVENGER HUNT**
**8 cards + answer loop key + 8 detailed solutions**
Post the 8 cards around the room in random order. Students solve a card, then find the next card whose **“Previous Answer”** matches. When the loop closes, students have completed all 8 problems.
### **SPECIAL EDUCATION MODIFIED VERSION**
**4 proofs + 4 solutions**
One proof for each method family: **SSS, SAS, ASA, HL**
Includes enlarged 1.5× diagrams, color-coded corresponding parts, and a printed sentence stem on every card.
### **STUDENT RECORDING SHEET**
One printable page for all **36 task cards + 8 scavenger hunt cards**.

### 💡 **HOW TO USE THIS RESOURCE**
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
**Option 1 — Sequential Progression (3–4 days)** Day 1: Tier A → Day 2: Tier B → Day 3: Tier C → Day 4: Scavenger Hunt review
**Option 2 — Differentiated Stations (1 day)** Three stations: Tier A / Tier B / Tier C. Assign students by readiness and rotate every 15 minutes.
**Option 3 — Homework + Review** Use Tier C cards for homework over 2 nights and the scavenger hunt for in-class self-checking review.
**Option 4 — IEP/SpEd Pull-Out** Use the Modified Version for the IEP setting and Tier A cards in the mainstream setting.
