Maple Valley Turkey Trot (Two Steps: Add & Subtract)
Correct Answer: 1,636 runners
A Step 1 (Add): 1,245 + 876 = 2,121
• Ones: 5 + 6 = 11 (write 1, carry 1)
• Tens: 1 + 4 + 7 = 12 (write 2, carry 1)
• Hundreds: 1 + 2 + 8 = 11 (write 1, carry 1)
• Thousands: 1 + 1 = 2 → 2,121 registered
Step 1 Sum = 2,121 runners
B Step 2 (Subtract): 2,121 − 485 = 1,636
• Ones: 1 − 5 → borrow: 11 − 5 = 6
• Tens: 1 − 8 → borrow: 11 − 8 = 3
• Hundreds: 0 − 4 → borrow: 10 − 4 = 6
• Thousands: 1 − 0 = 1 → 1,636 finished
Step 2 Difference = 1,636 runners
Final Sentence: "A total of 1,636 runners finished the race." Guide: Draw an arrow transferring Step 1's sum to Step 2!

• Multiply Tens: (4 × 2 tens) = 8 tens + 2 carried = 10 tens. Write 0 in tens, carry +1 hundred.
• Multiply Hundreds: (4 × 4 hundreds) = 16 hundreds + 1 carried = 17 hundreds. Write 7 in hundreds, 1 in thousands.

Instructional Accommodations for Students with Mild Intellectual Disabilities
1. Concrete Manipulatives Provide base-ten blocks (flats, rods, cubes) or colored place-value disks to physically model trading 10 ones for 1 ten rod.
2. Color-Coded Columns Have students highlight columns: Red for Thousands, Orange for Hundreds, Blue for Tens, Green for Ones to keep numbers aligned.
3. Chunking & Movement Administer one problem at a time. Offer a 1-minute brain break between Page 1 and Page 2 to prevent cognitive fatigue.
