Write tenths and hundredths as decimals
Decimals are already in your child's world: prices, race times, a height in meters, the readout on a kitchen scale. Seeing them as fractions written a new way keeps them from feeling like a separate topic. In 5th grade, your child extends decimals to thousandths and begins adding, subtracting, multiplying, and dividing them, and in middle school decimals connect to percents.
In this video, your child will learn to write tenths and hundredths as decimals.
The lesson stops at each question for your child's answer.
Three problems, each a little harder
Each problem is worked step by step. Your child will solve the last one before Bobby shows how.
Example 1
3/10 = ?
Example 2
4 27/100 = ?
Your child's turn
3 6/100 = ?
The three key steps
- 1Tenths: 1st place after point
- 2Hundredths: 2nd place after it
- 3Empty place? Write 0.
Mistakes to listen for
- Writing 7/100 as 0.7, leaving out the zero in the tenths place, which makes it ten times too big.
- Reading 0.62 as "point sixty-two" without knowing it means sixty-two hundredths.
- Thinking 0.50 is more than 0.5 because it has more digits, rather than seeing both as five tenths.

Is this the same lesson that's on YouTube?
Yes. Here, the lesson stops at each question and waits for your child to answer. On YouTube, each question stays on screen for a few seconds, and then the lesson plays on.
