Skill: Identify patterns on a number chart

A number chart helps you see how numbers change as you move.

• Move one space right: add $1$.
• Move one row down: add $10$.
• Numbers in the same column have the same ones digit.

Example: What pattern do you see in these numbers?

$$14,\ 24,\ 34,\ 44$$

1. Look at how the numbers change:

   • $14$ to $24$ is $+10$.
   • $24$ to $34$ is $+10$.
   • $34$ to $44$ is $+10$.

2. On a number chart, each number is one row below the one before it.

3. Look at the ones digits:

$$\boxed{14},\ \boxed{24},\ \boxed{34},\ \boxed{44}$$

They all end in $4$. The tens digit increases by $1$ each time.

Pattern: The numbers go down the same column. Each number is $10$ more than the number before it, and every number has the same ones digit, $4$.
