Mastering Decimal Multiplication Techniques

What is the purpose of using a model to multiply decimals?

• To make the problem more complex

• To visually represent the multiplication

• To avoid using a calculator

• To practice drawing grids

How many hundredths are shaded vertically on the grid?

• 40

• 30

• 20

• 10

What is the equivalent of 6 tenths in hundredths?

• 60 hundredths

• 0.6 hundredths

• 6 hundredths

• 600 hundredths

In which direction are the 60 hundredths shaded on the grid?

• Diagonally

• Randomly

• Vertically

• Horizontally

Why is it useful to convert 6 tenths to 60 hundredths?

• To make the numbers larger

• To avoid using fractions

• To use equivalent decimals for easier shading

• To simplify the calculation

What do you need to count to find the answer to the multiplication problem?

• The number of unshaded boxes

• The number of overlapping boxes

• The number of shaded boxes

• The total number of boxes

How many boxes overlap in the grid?

• 24

• 40

• 60

• 100

What is the product of 40 hundredths and 6 tenths?

• 0.24

• 0.4

• 0.6

• 0.06

What is the final step in finding the product using the model?

• Shading the entire grid

• Adding the shaded boxes

• Counting the total number of boxes
