**Patterns**

We have begun looking at the rows, columns and diagonals on the 100s chart to find patterns. Here are some examples:

**Pattern**: 10, 20, 30 40, 50, 60, 70, 80, 90, 100.

**Pattern Rule**: Start at ten. Add 10 each time until 100.

**Describe the pattern:**The digits in the one's place remain the same. The digits in the one's place are always zero. The digits in the ten's place increase.

**Place Value**

Please Note: Grade 2s will learn addition and subtraction with 2 digit numbers this year.

Here is an example of the concept of place value:

423

The

**digit**in the

**one's place**is

**3**. The

**digit**in the

**ten's place**is

**2.**The

**digit**in the

**hundred's place**is

**4**.

The

**value**of the 4 in the number above is 400.

Representing Numbers in Different Ways:

Base Ten Blocks

The picture to the left shows the number 325 with base ten blocks. There are 100 small cubes in a flat to make 100. Ten small cubes are in a stick to show 10. Each small cube represents the number 1.
