Understanding Decimal Representation and Place Value

This video tutorial teaches students how to convert fractions to decimal numbers up to the hundredths place using a grid model. It demonstrates how to represent 25 hundredths as a decimal by shading a grid and using a place value chart. The lesson emphasizes understanding the relationship between fractions and decimals, and concludes with encouragement to continue learning in the series.

What is the purpose of using a grid model in this lesson?

• To help students visualize fractions as decimals

• To explain geometric shapes

• To teach multiplication

• To introduce algebraic expressions

How many parts of the grid should be shaded to represent 25 hundredths?

• 100 parts

• 50 parts

• 25 parts

• 10 parts

What is the next step after shading the grid to show 25 hundredths?

• Multiply by 10

• Divide by 2

• Convert it to a percentage

• Write it in a place value chart

What is another way to think of 25 hundredths?

• As one group of fifty hundredths

• As two groups of ten hundredths and five hundredths

• As four groups of five hundredths

• As three groups of ten hundredths

How can 25 hundredths be broken down into smaller parts?

• Into three groups of five-tenths

• Into two groups of ten hundredths and five hundredths

• Into five groups of five-tenths

• Into one group of twenty-five hundredths

In a place value chart, where should the number '2' be placed to represent two-tenths?

• In the hundredths place

• In the tenths place

• In the units place

• In the thousandths place

What number should be written to the left of the decimal point when writing 25 hundredths as a decimal?
