You're looking at a set of
Doubles Addition Flash Cards. These are designed to help learners practice adding a number to itself — also known as “doubling” a number.
Each card shows an addition problem where both addends are the same:
1 + 1, 2 + 2, 3 + 3, ..., up to 10 + 10
---
✔ Here are the solutions for each flash card:
#### Top Row:
1.
1 + 1 = 2
2.
2 + 2 = 4
3.
3 + 3 = 6
4.
4 + 4 = 8
5.
5 + 5 = 10
#### Bottom Row:
6.
6 + 6 = 12
7.
7 + 7 = 14
8.
8 + 8 = 16
9.
9 + 9 = 18
10.
10 + 10 = 20

🧠 Why Learn Doubles?
Learning doubles is a foundational math skill because:
- It helps build fluency in mental math.
- It’s a stepping stone to learning near-doubles (like 6 + 7 = 6 + 6 + 1 = 13).
- It reinforces the concept of multiplication later on (e.g., 5 + 5 = 10 is the same as 5 × 2).
