Part 1: Spiral Warm-Up Solutions
1. Value Check:
Answer: 53
4 tens + 13 ones = 4 tens + 1 ten + 3 ones = 5 tens + 3 ones = 53.
2. Mental Snap:
Answer: 88
50 + 30 = 80; 80 + 8 = 88. Tens jump first!
3. True or Bogus?
Answer: Bogus! (64)
The student added 8 instead of subtracting, or subtracted 2 then added 6.
Guided & Independent Practice Solutions
Problem A: 56 + 28 Answer: 84
• Ones: 6 + 8 = 14 ones = 1 ten and 4 ones.
• Tens: 1 (regrouped) + 5 + 2 = 8 tens.
• Watch out: Students who write "714" forgot to bundle into the tens column!
Problem B: 62 - 27 Answer: 35
• Cannot do 2 - 7 without unbundling.
• 6 tens becomes 5 tens; 2 ones becomes 12 ones.
• 12 - 7 = 5 ones; 5 - 2 = 3 tens = 35.
• Watch out: Students subtracting 7 - 2 = 5 (upside-down subtraction).
Problem 1: 48 + 37 Answer: 85
• 8 + 7 = 15 ones (bundle 10 into 1 ten, keep 5 ones).
• 1 + 4 + 3 = 8 tens = 85 tacos.
Problem 2: 81 - 45 Answer: 36
• Trade 1 ten: 8 tens becomes 7; 1 one becomes 11 ones.
• 11 - 5 = 6 ones; 7 - 4 = 3 tens = 36 burritos.
Problem 3: 90 - 37 (Across Zero) Answer: 53
• 0 - 7 cannot happen. Unbundle 1 ten from 9 tens (becomes 8 tens).
• Ones room now has 10 ones. 10 - 7 = 3 ones. 8 tens - 3 tens = 5 tens = 53 chips.
Exit Ticket Key & Quick Scoring
Task 1: 39 + 45 = 84
9 + 5 = 14 (1 ten bundled, 4 ones left).
1 + 3 + 4 = 8 tens. Sketch must circle 10 dots.
Pass criteria: 84 with clear bundling indicator (+1 ten).
Task 2: 73 - 28 = 45
7 crossed out ➔ 6. 3 crossed out ➔ 13.
13 - 8 = 5 ones; 6 - 2 = 4 tens.
Pass criteria: 45 with visible crossing out/regrouping marks.
Teacher Humor Delivery: When students want to subtract smaller from larger on the bottom (like 2 - 7 = 5), tell them: "If you have 2 cookies in your lunchbox, can your friend eat 7 of your cookies? No! You'll cry! Go knock on the tens door!" 🍪🚪

Part 1: Spiral Warm-Up Solutions
1. Day 1 Add (67 + 25):
Answer: 92
7 + 5 = 12 (bundle 1 ten); 1 + 6 + 2 = 9 tens = 92.
2. Day 1 Subtract (84 - 39):
Answer: 45
Unbundle 8 tens ➔ 7 tens; 14 - 9 = 5; 7 - 3 = 4 tens = 45.
3. Group Counting:
Answer: 20 coins
5 + 5 + 5 + 5 = 20 (4 groups of 5 = 4 × 5 = 20).
Guided & Independent Solutions
Problem A: 458 + 276 Answer: 734
• Ones: 8 + 6 = 14 (bundle 1 ten to tens column, 4 ones left).
• Tens: 1 + 5 + 7 = 13 tens (bundle 1 hundred to hundreds column, 3 tens left).
• Hundreds: 1 + 4 + 2 = 7 hundreds.
• Total: 734 . Both columns require bundling.
Problem B: 4 rows of 7 lasers Answer: 28
• Equation: 4 × 7 = 28 (or 7 + 7 + 7 + 7 = 28).
• Array sketch must show 4 rows with 7 items per row.
• Emphasize rows = horizontal, columns = vertical.
Problem 1: 387 + 459 Answer: 846
• 7 + 9 = 16 (1 ten carried).
• 1 + 8 + 5 = 14 tens (1 hundred carried).
• 1 + 3 + 4 = 8 hundreds = 846 gold bars.
Problem 2: 500 - 238 (Across Zeros) Answer: 262
• Unbundle 5 hundreds ➔ 4 hundreds, tens becomes 10.
• Unbundle 10 tens ➔ 9 tens, ones becomes 10.
• 10 - 8 = 2; 9 - 3 = 6; 4 - 2 = 2 ➔ 262 diamonds.
Problem 3: 6 trays of 8 keys Answer: 48
• Repeated addition: 8 + 8 + 8 + 8 + 8 + 8 = 48.
• Multiplication sentence: 6 × 8 = 48 keys.
Exit Ticket Key & Quick Scoring
Task 1: 604 - 278 = 326
6 hundreds becomes 5; 0 tens becomes 9; 4 ones becomes 14.
14 - 8 = 6; 9 - 7 = 2; 5 - 2 = 3.
Common mistake alert: Writing 8 - 4 = 4 or 0 - 7 = 7.
Task 2: 5 bags × 7 jewels = 35
Draw 5 groups/circles with 7 dots each, or a 5×7 grid.
Multiplication sentence: 5 × 7 = 35 jewels.
Pass criteria: Model matches equation with product 35.
Safe-Cracker Scaffolding Tip: When teaching subtraction across zeros (e.g. 500 - 238), call the middle zero the "empty hallway". You can't borrow sugar from an empty hallway! You have to go all the way to the hundreds kitchen, convert it to 10 tens in the hallway, and then take 1 into the ones bedroom (leaving 9 tens in the hallway). Students never forget this story! 🏠🥞
