What Are Addition Input/Output Tables?
Addition input/output tables are like magic number machines!
They show us how numbers change when we add a special number to them. The "input" is the number we start
with, and the "output" is what we get after adding. It's like a fun puzzle where we figure out the
pattern!
How to Solve Addition Input/Output Tables
1️⃣ Look at the first row - Find a complete input and output pair
2️⃣ Find the pattern - What number is being added each time?
3️⃣ Apply the pattern - Use the same addition for other numbers
Let's Try Some Examples!
Example 1: The Apple Tree
Every day, the apple tree gets 5 more apples! Can you complete the table?
| Day | Apples in Morning (Input) | Apples Added | Apples in Evening (Output) |
|---|---|---|---|
| Monday | 10 | +5 | 15 |
| Tuesday | 12 | +5 | |
| Wednesday | +5 | 22 |
Example 2: The Cookie Jar
Every time we add 8 cookies to the jar! Fill in the missing numbers.
| Time | Cookies Before (Input) | Cookies Added | Cookies After (Output) |
|---|---|---|---|
| Breakfast | 15 | +8 | 23 |
| Lunch | 20 | +8 | |
| Dinner | +8 | 35 |
Parent Tips 🌟
- Make it real: Use physical objects like toys or snacks to create live input/output tables your child can manipulate.
- Daily practice: Create simple addition tables based on everyday activities (like how many grapes are eaten each day).
- Celebrate patterns: Help your child see that once they find the addition pattern, all the problems become easier!
