Decimal Division Techniques for 5th Graders

The video tutorial introduces the box strategy for division, which is similar to long division but uses a different layout to help students organize their work. The instructor demonstrates solving a division problem with a double-digit divisor and then with a decimal divisor, emphasizing the importance of setting up the problem correctly and using multiplication facts to aid in solving. The tutorial highlights the steps of the box strategy, including drawing lines to create boxes, bringing numbers over, and adjusting for decimals.

What is the first step in setting up the box strategy for division?

• Write down the multiplication facts

• Place the dividend inside the symbol

• Move the decimal point

• Draw the boxes

Why is the decimal in a different place in the quotient when dividing by 0.15 instead of 15?

• Because the divisor is a decimal

• Because the multiplication facts change

• Because the dividend is different

• Because the problem is set up differently
