What was Alex's bug? He forgot to .
True Correct Answer: 46 × 4 =

👧‍🎓 Chloe's Work

Bug 2: Chloe calculated 624 ÷ 6:

624 ÷ 6 = 14 ❌

She thought: "6 ÷ 6 = 1. Then 24 ÷ 6 = 4. So my quotient is 14!"

What was Chloe's bug? She forgot the .
True Correct Answer: 624 ÷ 6 =

⚙️ PART A: Two-Step Math Machines (Multiply, then Divide!) 6 Points Total

💡 How the Machines Work: Start with the Input Number. Follow Step 1 to multiply, write the intermediate answer in the first box, then carry that number into Step 2 to divide and find the Final Output!

MACHINE A Rule: [ × 6 ] ➔ [ ÷ 3 ]

Input	Step 1: Multiply (× 6)	Step 2: Divide (÷ 3)	Final Output
12	12 × 6 = 72	72 ÷ 3 = 24	24 ✓ (Example)
20	20 × 6 =	Answer ÷ 3 =
45	45 × 6 =	Answer ÷ 3 =
80	80 × 6 =	Answer ÷ 3 =

MACHINE B Rule: [ × 4 ] ➔ [ ÷ 8 ]

Input	Step 1: Multiply (× 4)	Step 2: Divide (÷ 8)	Final Output
32	32 × 4 = 128	128 ÷ 8 = 16	16 ✓ (Example)
50	50 × 4 =	Answer ÷ 8 =
64	64 × 4 =	Answer ÷ 8 =

📊 Grade 4 Speed & Fluency Diagnostic Benchmarks

• Basic Fact Fluency: 20 facts in under 60 seconds indicates automatic memory retrieval (no finger counting).
• Zero Trick Conceptualization: Mentally separating base facts from power-of-10 zero counts ensures algebraic readiness.
• Tutor Coaching Tip: When students hesitate on division with zeros (e.g. $624 \div 6$), reinforce estimating first: $600 \div 6 = 100$, so the answer must be around 100, not 14!
