Compare three decimal numbers by placing them on a number line to determine the order of the numbers from least to greatest or greatest to least. Then arrange the numbers to form a double inequality statement to show the comparison

Order decimal numbers in a double inequality statement

Order three decimal numbers from least to greatest or greatest to least using inequality symbols

Order four decimal numbers in ascending order

Order four decimal numbers from least to greatest. Can you find the order before losing all three lives?

Order decimals, fractions, and decimal numbers in unit form in a double inequality statement based on a number line

Place three decimals, fractions, or decimals in unit form on a number line, and use the number line to help you order the numbers from least to greatest using inequality symbols

Order decimals, mixed numbers, and decimal numbers in unit form in a double inequality statement

Order three decimals, fractions, or decimals in unit form from least to greatest or greatest to least using inequality symbols

Order four decimals, mixed numbers, and decimal numbers in unit form in ascending order

Order four or five numbers written in decimal form, fraction form, or unit form from least to greatest by dragging the numbers to the correct positions

Students rely on their mastery of converting between decimals, fractions, and mixed numbers in order to add tenths and hundredths. They learn how to add different units (tenths to hundredths) in both fraction and decimal form. They also learn to record their sum without improper fractions.

Regroup to add tenths to hundredths with and without a disk model

Find the sum of numbers given in unit form. Then find the sum of numbers in unit form using the disk model in a place value chart, converting tenths to hundredths in order to add

Rewrite decimals in fraction form to add

Rewrite decimals less than 1 in fraction form in order to add, then write the answer in decimal form

Rewrite mixed number decimals in fraction form to add

Rewrite decimals greater than 1 as mixed numbers in order to add, then write the answer in decimal form

Add tenths and hundredths fractions by making an equivalent fraction

Add two fractions - one in tenths and one in hundredths - by first rewriting one of the fractions so there is a common denominator, and then adding. Write the answer as a decimal

Rewrite decimals in fraction form and find an equivalent fraction to add

Rewrite two decimals, one in tenths and one in hundredths, in fraction form to add. Then write the answer as a decimals
