Adding Decimal Fractions Mentally

Learners count by tenths, hundredths, or tens in a task that uses decimal place value strategies. The young mathematicians then use <, >, or = to make correct comparisons between expanded decimal notations.

Four hundredths + one tenth = 14 hundredths. Learners complete place order equations in order to make each equation true. Hundredth and tenths are the focus of the worksheet.

Model decimals and explore decimal place value with a useful printable. The worksheet showcases decimal square models representing one whole, tenths, hundredths, and thousandths.

Practice adding decimals by completing 26 practice problems. Scholars examine two examples before trying these on their own. They add two and three-digit numbers with decimals, regrouping when needed. Not all numbers have decimals, but...

Building strong mental-math skills requires learners to have a strong number sense. They practice multiplying two and three-digit numbers in their heads using estimation or approximation. They estimate or round each number and then...

Having a good number sense is key to understanding place value. This video clearly explains the place values that comprise a decimal number. It is a very straight forward presentation and would be appropriate for grades 3, 4, or 5. Sal...

Rounding numbers is an essential skill to have for all math classes. Sometimes those decimal numbers are just too big, and sometimes an answer should only be given out to the hundredths (like money). So watch this video to see the rules...

Young mathematicians represent recorded information in decimal form. For this decimals lesson, learners play a "classroom friendly" basketball game in which pupils take 10 shots. Number of shots made out of 10 is recorded as a fraction...

Learners practice mental math skills by playing an online game,"Place Value!" A random number is generated either by the student or the computer. Individuals are asked to identify the place value of a specific digit, or to select the...

[Free Registration/Login may be required to access all resource tools.] For this learning module, students are asked to state the decimals to the hundredths place for given locations on a number line. Includes video demonstrating a...
