Adding by Place Value with Base Ten Blocks

The video tutorial explains how to add numbers using place value and the standard algorithm. It begins with an introduction to adding by place value using base ten blocks to visualize numbers. The tutorial then demonstrates the standard algorithm for addition, showing how to align numbers by their place values. Examples are provided to illustrate both methods, and the connection between base ten blocks and the written method is highlighted. The tutorial emphasizes the mental strategy of breaking down numbers by place value for flexible thinking.

Why is adding by place value a good mental strategy?

• It's faster than writing.

• It requires less memory.

• It allows flexibility in thinking about numbers.

• It's the only way to add large numbers.

What does the standard algorithm align for addition?

• Numbers randomly

• Numbers by their symbols

• Numbers by their size

• Numbers by their place values

What is the purpose of lining up numbers in the standard algorithm?

• To compare the size of numbers

• To make the numbers look organized

• To ensure correct addition of symbols

• To match the place values for accurate addition
