🔽 The "V-Funnel" Rule

Underline first move, rewrite the rest below!

Instructions: Look at each expression. Underline the operation that MUST be solved first! Then write its operator sign (+, -, ×, ÷) in the blank.

1. 16 - 3 × 4

2. 35 ÷ 7 + 8

3. 9 + 6 × 5

4. 28 - 20 ÷ 4

5. 12 ÷ 3 × 2

6. 8 × 4 - 15

7. 14 + 18 ÷ 2

8. 30 - 8 + 6

Instructions: Solve the underlined first step into the dashed box. Then solve the remaining step into the green box!

#1 8 + 4 × 6

= 8 + ➔ Final:

#2 30 - 18 ÷ 3

= 30 - ➔ Final:

#3 7 × 5 - 12

= - 12 ➔ Final:

#4 45 ÷ 9 + 16

= + 16 ➔ Final:

#5 50 - 6 × 7

= 50 - ➔ Final:

#6 24 + 36 ÷ 4

= 24 + ➔ Final:

#7 9 × 9 - 35

= - 35 ➔ Final:

#8 60 + 72 ÷ 8

= 60 + ➔ Final:

⚔️ Left-to-Right Twin Showdown & Error Detective

GRADE 4 EQUAL TWINS

Name:

Date:

Score: / 13 ⭐

Crucial Rule: Multiplication (×) and Division (÷) are equal twins! Addition (+) and Subtraction (-) are equal twins! When both appear, solve whichever comes FIRST on the left!

Track 1: Division on the Left vs. Multiplication on the Left

÷ is Left (Solve ÷ first!)

24 ÷ 4 × 2

= × 2 =

× is Left (Solve × first!)

24 × 2 ÷ 4

= ÷ 4 =

Track 2: Subtraction on the Left vs. Addition on the Left

- is Left (Solve - first!)

30 - 10 + 5

= + 5 =

+ is Left (Solve + first!)

30 + 10 - 5

= - 5 =

Track 3: Mixed Operations (Who's on the Left?)

Solve ÷ first:

40 ÷ 8 × 3

= × 3 =

Solve ÷ first:

18 ÷ 3 × 2

= × 2 =

Scenario: A student made classic MDAS mistakes. Circle the wrong step, identify the trap, and solve it correctly in the Green Box!

BUG #1: Blind Left-to-Right ❌ WRONG

Problem: 5 + 4 × 3
Student did: 5 + 4 = 9
Then did: 9 × 3 = 27 🛑

✔ Correct Solution:

5 + (4 × 3) = 5 + _____ = _____

BUG #2: "M Always First" Trap ❌ WRONG

Problem: 18 ÷ 3 × 2
Student did: 3 × 2 = 6
Then did: 18 ÷ 6 = 3 🛑

✔ Correct Solution:

(18 ÷ 3) × 2 = _____ × 2 = _____

BUG #3: "A Always First" Trap ❌ WRONG

Problem: 20 - 7 + 3
Student did: 7 + 3 = 10
Then did: 20 - 10 = 10 🛑

✔ Correct Solution:

(20 - 7) + 3 = _____ + 3 = _____

Instructions: Underline the first operation. Show the intermediate expression, then write the final answer!

#1: 12 + 6 × 3 - 10 [× goes first]

= 12 + - 10
= - 10 =

#2: 50 - 24 ÷ 6 + 7 [÷ goes first]

= 50 - + 7
= + 7 =

#3: 8 × 4 + 18 ÷ 2 [Solve × & ÷ before +]

= +
= Final Answer:

#4: 36 ÷ 4 × 2 - 5 [÷ on left first!]

= × 2 - 5
= - 5 =

💡 Tutor Intervention & Diagnostic Guide:
• If child computes left-to-right blindly (e.g. 5 + 4 × 3 = 27): Have them draw a physical red traffic light over × and ÷ before touching pencil to paper.
• If child always multiplies before dividing (e.g. 18 ÷ 3 × 2 = 3): Remind them that × and ÷ are equal twins born at the exact same second—whoever is standing on the left gets served first!
