Decimal Place Value and Operations

Decimal Place Value and Operations

Course overview

This course helps Grade 5 students understand decimal place value and use decimals in real situations. Students learn to read decimal digits carefully, add and subtract decimals with aligned place value, and multiply decimals when a situation calls for money, measurement, or a word problem.

What students will learn

• Read decimal digits as tenths, hundredths, and thousandths.
• Compare decimals using place value.
• Add and subtract decimals with decimal points aligned.
• Multiply decimals in practical contexts.
• Check whether a decimal answer makes sense.

Lessons

• Decimal Place Value - Learn how the digits to the right of the decimal point change the value of a number.
• Add and Subtract Decimals - Learn how to line up decimal points and keep place values aligned.
• Multiply Decimals in Context - Learn how decimal multiplication shows up in money, measurement, and word problems.

Parent guide

Pace the course in short sessions. Use money, rulers, and measurement examples so the child can connect the digits to something real. Ask them to explain each answer with place-value words instead of just reading the final number.

Completion

A student finishes this course when they can explain decimal place value, add and subtract decimals accurately, and use decimal multiplication to solve a simple real-world problem.
