SWStephanie Wooten

Equation: \((4 \times 4) + 7 = g\)

Tip: Clarify vocabulary: "quartet" means a group of 4.

8. Toxic Slime Flasks 12 ounces

Step 1: \(132 - 24 = 108\text{ oz slime}\)

Step 2: \(108 \div 9 = 12\text{ oz per flask}\)

Equation: \((132 - 24) \div 9 = s\)

Tip: Subtraction step must precede division into 9 flasks.

9. Cursed Pumpkin Patch 69 pumpkins

Step 1: \(6 \times 18 = 108\text{ total pumpkins}\)

Step 2: \(108 - 39 = 69\text{ undamaged}\)

Equation: \((6 \times 18) - 39 = p\)

Tip: Array model: 6 rows of 18 equals 108 total.

10. Shadow Wolf Claw Marks 97 marks

Step 1: \(64 + 78 = 142\text{ total claw marks}\)

Step 2: \(142 - 45 = 97\text{ marks left}\)

Equation: \((64 + 78) - 45 = c\)

Tip: Add Monday + Tuesday first, then subtract sanded marks.

Complete Step-by-Step Solutions & Equations • Problems 11–20

Problems 11–20 Solutions

11. Sleeping Vampire Bats 59 bats

Step 1: \(3 \times 26 = 78\text{ sleeping bats}\)

Step 2: \(78 - 19 = 59\text{ bats remaining}\)

Equation: \((3 \times 26) - 19 = b\)

Tip: \(3 \times 20 = 60\) plus \(3 \times 6 = 18 \rightarrow 78\).

12. Frankenstein's Neck Bolts 19 bolts

Step 1: \(3 \times 24 = 72\text{ bolts total}\)

Step 2: \(72 - (38 + 15) = 72 - 53 = 19\text{ bolts}\)

Equation: \((3 \times 24) - (38 + 15) = b\)

Tip: Combine used bolts \((38 + 15 = 53)\) before subtracting.

13. Ghoul Manor Ticket Booth $337

Step 1: \(8 \times \$9 = \$72\text{ youth tickets}\)

Total In: \(\$350 + \$72 = \$422\)

Step 2: \(\$422 - \$85 = \$337\text{ remaining}\)

Equation: \((350 + (8 \times 9)) - 85 = m\)

Tip: Remember the dollar sign ($) in the final unit.

14. Sour Candied Worms 90 bags

Step 1: \(85 + 65 = 150\text{ bags shipped}\)

Step 2: \(240 - 150 = 90\text{ bags left}\)

Equation: \(240 - (85 + 65) = c\)

Tip: Alternate step: \(240 - 85 = 155\), then \(155 - 65 = 90\).

15. Tombstone Stone Chisels 92 chisels

Step 1: \(9 \times 12 = 108\text{ total chisels}\)

Step 2: \(108 - 16 = 92\text{ working chisels}\)

Equation: \((9 \times 12) - 16 = c\)

Tip: Basic 12s fact: \(9 \times 12 = 108\).

16. Midnight Witch Flight 52 witches

Step 1: \(5 \times 14 = 70\text{ total witches}\)

Step 2: \(70 - 18 = 52\text{ flying witches}\)

Equation: \((5 \times 14) - 18 = w\)

Tip: \(5 \times 14 = 5 \times (10 + 4) = 50 + 20 = 70\).

17. Ghost Bridge Toll Tokens 139 tokens

Step 1: \(13 \times 7 = 91\text{ tokens collected}\)

Step 2: \(48 + 91 = 139\text{ tokens in chest}\)

Equation: \(48 + (13 \times 7) = t\)

Tip: Multi-step addition with initial chest quantity.

18. Cellar Rat Swarm 120 rats

Step 1: \(184 - 96 = 88\text{ remaining}\)

Step 2: \(4 \times 8 = 32\text{ new baby rats}\)

Total: \(88 + 32 = 120\text{ crawling rats}\)

Equation: \((184 - 96) + (4 \times 8) = r\)

Tip: Notice the three-phase operations: subtract, multiply, add.

19. Queen's Poisoned Apples 29 apples

Step 1: \(9 \times 16 = 144\text{ apples picked}\)

Step 2a: \(144 - 28 = 116\text{ good apples}\)

Step 2b: \(116 \div 4 = 29\text{ apples per barrel}\)

Equation: \(((9 \times 16) - 28) \div 4 = a\)

Tip: \(116 \div 4 = (100 \div 4) + (16 \div 4) = 25 + 4 = 29\).

20. Iron Coffin Nails 30 nails

Step 1: \(4 \times 35 = 140\text{ nails total}\)

Step 2: \(68 + 42 = 110\text{ nails used}\)

Left: \(140 - 110 = 30\text{ nails remaining}\)

Equation: \((4 \times 35) - (68 + 42) = n\)

Tip: Grouping used nails makes mental subtraction easy: \(140 - 110 = 30\).

Targeted Coaching Prompts & Hidden Step Analysis • Problems 7–14

Problems 7–14

#7

Hidden Step 1: Ghosts in quartets (\(4 \times 4 = 16\)).

Common Misconception: Unfamiliar with word "quartet".

Whisper Prompt: "Quartet means a group of 4. There are 4 groups of 4 ghosts."

#8

Hidden Step 1: Slime left after spill (\(132 - 24 = 108\text{ oz}\)).

Common Misconception: Dividing 132 by 9 directly (gives remainder).

Whisper Prompt: "If slime spilled on the book, it's gone! Subtract 24 before dividing."

#9

Hidden Step 1: Total pumpkins grown (\(6 \times 18 = 108\)).

Common Misconception: Subtracting 39 from 18 directly.

Whisper Prompt: "Picture 6 rows with 18 in each row. How many grew in the patch first?"

#10

Hidden Step 1: Total marks made (\(64 + 78 = 142\)).

Common Misconception: Subtracting 45 from only one day's count.

Whisper Prompt: "How many marks were made over both days before any were sanded?"

#11

Hidden Step 1: Total bats sleeping (\(3 \times 26 = 78\)).

Common Misconception: Subtracting \(26 - 19\) and ignoring the 3 clusters.

Whisper Prompt: "There are 3 clusters of 26. Find the cave total before the storm."

#12

Hidden Step 1: Starting bolts (\(3 \times 24 = 72\)).

Whisper Prompt: "Victor used 38 AND gave away 15. How many bolts were used in total?"

#13

Hidden Step 1: Youth ticket revenue (\(8 \times \$9 = \$72\)).

Common Misconception: Adding \(8 + 9 = 17\) instead of multiplying.

Whisper Prompt: "8 tickets at $9 each. What is the value of those tickets?"

#14

Hidden Step 1: Total bags shipped (\(85 + 65 = 150\)).

Common Misconception: Doing only one subtraction step.

Whisper Prompt: "Combine the two orders that shipped out, then subtract from 240."

Whisper Prompt: "4 litters with 8 pups each = 32 new rats. Add that to the 88 left."

#19

Hidden Step 1: Harvest (\(144\)), good apples (\(116\)).

Trap: Dividing 144 before subtracting rotten.

Whisper Prompt: "Throw away rotten apples first! What is \(144 - 28\)? Now divide by 4."

#20

Hidden Step 1: Total nails bought (\(4 \times 35 = 140\)).

Trap: Forgetting one of the two repair uses.

Whisper Prompt: "Add \(68 + 42\) to see total nails used, then subtract from 140."

IEP / 504 Accommodations & Small Group Interventions

1. Visual & Color Coding:

Provide two highlighters: yellow for Step 1 data and orange for Step 2 data. This visually splits the paragraph into two bite-sized tasks.

2. Chunking & Pacing:

Cover Problems 3–4 with blank construction paper while the student focuses solely on Problem 1 or 2 to eliminate visual overwhelm.

3. Concrete Manipulatives:

Have base-ten blocks, place value charts, or multiplication fact grids ready for students who grasp the logic but struggle with multi-digit operations.

Pacing Guide: 4 problems per session (1 page/day) for tiered intervention groups. Praise Effort: "I love how you found the hidden question first!"
