# Adding and Subtracting Numbers within 1000 using Concrete Models 2nd Grade Math Worksheets

Looking for the best way to teach students about adding and subtracting numbers within 1000 using concrete models?

This premium worksheet bundle contains 10 activities to challenge your students and help them understand the adding and subtracting numbers within 1000 using concrete models.

## Definition:

This worksheet teaches adding and subtracting within 1000, using concrete models or drawings based on place value, properties of operations, and/or the relationship between addition and subtraction.

Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones. Sometimes it is necessary to compose or decompose tens or hundreds before proceeding to the operation.

## Summary:

NUMBER LINE – An open number line is very flexible. We can make jumps of one or ten (or more) and easily manipulate it to show their mathematical thinking. When we add, we jump from left to right. But when we subtract, we jump from right to left.

BASE (10 BLOCKS) – We draw each number in tens, then count by tens until they go to 100. Then we can start over by counting by 10s again. Not only did this help us add up numbers beyond 100, but it also give us more expense with our base-10 number system.
