# Base Ten Blocks Worksheets

Welcome to the base ten blocks page at Math-Drills.com where blocking your students' learning is the best approach! On this page, you will find several worksheets for base ten block manipulatives. Base ten blocks are an excellent tool for teaching children math number concepts because they allow children to touch and manipulate something real while learning important skills that translate well into paper and pencil addition. They are also proportional representations of numbers, so that a thousand block is actually 1000 times greater in size than a one block.

## Counting Base Ten Blocks Worksheets

Counting base ten blocks worksheets including counting units, rods and flats.

Although we recommend using actual base ten blocks, not everyone has access to them, and some students like to use them as projectiles or for other purposes not related to learning. Counting various base ten blocks and turning them into numbers is a necessary skill to have in order to trade and represent numbers with base ten blocks.

## Trading Base Ten Blocks Worksheets

Trading base ten blocks worksheets for developing regrouping skills.

Trading blocks both ways will help a great deal when adding and subtracting numbers with base ten blocks, so don't skip this part.

## Representing Numbers With Base Ten Blocks Worksheets

Representing numbers with base ten blocks worksheets help students learn how to represent numbers, so they can use base ten blocks for addition, subtraction, multiplication or division.

The worksheets in this section ask students what each group of blocks represents. The natural next step is to have students represent their own representations of numbers using base ten blocks. Encourage them to make each number out of the fewest blocks in each case. For example, they would model the number 14 with a rod and four units rather than 14 units.

To add numbers with base ten blocks, students model both numbers and combine the piles. They trade any piles ten or greater for larger blocks, staring with the units pile. To subtract numbers, students model the first number, then remove enough blocks to make the second number. This often involves "borrowing" or "regrouping" where a larger block must be traded for smaller blocks to facilitate the removal.
