83 - 29:

DAY 2 SLIP: Titanium Vault Clearance 564 + 289 = 853  |  700 - 346 = 354  |  7 × 6 = 42

• 564 + 289: 4+9=13 (carry 1); 1+6+8=15 (carry 1); 1+5+2=8 hundreds. Total = 853.
• 700 - 346: Unbundle 700 into 6 hundreds, 9 tens, 10 ones. 10-6=4; 9-4=5; 6-3=3. Difference = 354.
• 7 × 6: 7 rows of 6 = 42 gold bars.

DAY 3 SLIP: Alien Signal Decoder 34 × 18 = 612  |  92 ÷ 4 = 23

• 34 × 18: (30×10 = 300) + (30×8 = 240) + (4×10 = 40) + (4×8 = 32). Sum = 300 + 240 + 40 + 32 = 612.
• 92 ÷ 4: Big 7 bite 1: 4 × 20 = 80 (Leaves 12). Bite 2: 4 × 3 = 12. Total quotient = 20 + 3 = 23.

Part 2: Comprehensive Capstone Ticket Solutions (4/4 Points)

Skill 1: 71 - 38 = 33

• Trade 1 ten: 7 tens ➔ 6 tens; 1 one ➔ 11 ones.
• 11 - 8 = 3; 6 - 3 = 3 ➔ 33.

Skill 2: 800 - 463 = 337

• Regroup 8 hundreds ➔ 7 hundreds, 9 tens, 10 ones.
• 10 - 3 = 7; 9 - 6 = 3; 7 - 4 = 3 ➔ 337.

Skill 3: 42 × 15 = 630

• Rooms: 40×10 = 400 | 40×5 = 200 | 2×10 = 20 | 2×5 = 10.
• 400 + 200 + 20 + 10 = 630.

Skill 4: 112 ÷ 4 = 28

• Big 7 bites: 4 × 20 = 80 (Leaves 32).
• 4 × 8 = 32 (Leaves 0). Quotient = 20 + 8 = 28.

Teacher Grading Note: This capstone provides diagnostic insight into whether students have transitioned from additive reasoning to multiplicative reasoning (Area Model & Partial Quotients). Use it as a post-test or formative Friday check!
