Why Fast Mental Math Matters

3 Fast Math Strategies Kids Can Use Today

1. The "Plus 9" Hack (Add 10, then Subtract 1)

This keeps the math simple and fast. Instead of counting up 9 times, just jump to the next ten.

Quick Example
35 + 9 → 35 + 10 = 45, then 45 - 1 = 44
Practice Prompt
Try five problems like 27 + 9 and 68 + 9.

2. Doubling for Multiplication (The Double-Double)

Multiply by 4 by doubling twice. This is one of the fastest mental arithmetic techniques for early multiplication.

Quick Example
15 × 4 → 15 + 15 = 30, then 30 + 30 = 60
Practice Prompt
Double twice: 12 × 4, 18 × 4, 25 × 4.

3. The "Split" Strategy (Tens and Ones)

Split tens and ones, then combine. This is a core number sense activity that builds mental organization.

Quick Example
24 + 32 → 20 + 30 = 50, 4 + 2 = 6, total 56
Practice Prompt
Split and add: 46 + 23 and 58 + 17.
