Addition input/output tables – up to two digits

key notes :

🔢 What is an Input/Output Table?

• It is a small table that shows how numbers change.
• You put a number in → follow a rule → get a new number out.
• Input = starting number
• Output = answer after rule
  ✨ Think of it like a magic math machine! 🪄🤩

---

➕ Addition Rule

The table uses a rule, such as:

• “Add 3”
• “Add 7”
• “Add 10”

Whatever number goes into the input, you add the rule number to get the output.
📘 Example:
Rule: Add 5
Input: 7 → Output: 12
💭 Because 7 + 5 = 12

---

🧠 How to Use the Table

1️⃣ Look at the rule.
2️⃣ Take the number in the input box.
3️⃣ Add the rule number.
4️⃣ Write the new number in the output box.
🎯 It’s simple: Input + Rule = Output

🎨 Sample Table

🌟 Input	➕ Rule: Add 4	🌈 Output
6	+4	10
9	+4	13
12	+4	16

🧩 Because we add 4 to every input number!

🔍 Look for Patterns

• When you add the same number each time, the outputs grow in a pattern.
• The difference between each output is the same too!
  🎉 This helps kids notice number patterns easily.

🎯 Why Input/Output Tables Are Important

• They build addition fluency.
• They help children understand math rules.
• They make it easier to work with patterns and functions later.
  💡 It’s a great way to practice logical thinking!
