Learning objectives

After paying attention to the explanation of the learning video about rounding fractions, students can do the rounding of ordinary, mixed, decimal and percent fractions correctly. After reading the material on the use of Natural Resources about castor oil, students are able to correctly identify the use of castor oil and its relation to the welfare of the community.

Great children, at the last meeting we learned about rounding numbers to the nearest unit, the nearest tens, the nearest hundreds and the nearest thousands, this time we will continue to study the material for rounding fractions from common fractions, mixed fractions, decimals, and percents. We need to do rounding to make the calculation easier. Pay attention to the rounding rules so you can easily understand them.

So that you can better understand how to round fractions, please watch the video explanation at the link below!


How is a great child, do you understand? I hope you understand this explanation!

In order to increase your understanding, please do the practice questions in the following LKPD!

When finished, please send the photos to your teacher!

Have a great time doing it!

Great kids, your next activity will learn about the use of alternative energy sources, especially castor oil. There are many alternative energy sources around us, such as wind, water, solar, biomass, castor oil and many other examples.

Great kids, let’s read carefully the reading on the link below yes!

Castor Oil as an Alternative Energy Source

Castor oil is becoming known as an alternative energy source for biodiesel. Biodiesel is produced from oil obtained from the seeds of the jatropha plant which is widely grown in tropical areas such as Indonesia.

The castor oil from the seeds of this hedge plant has
potential to be developed as an oil-producing plant as a substitute for petroleum fuel, because it has several advantages. One of the advantages of castor oil is that this plant is easy to cultivate, so it can guarantee the availability of raw materials. The processing process is quite simple so that it is easily carried out by the general public, does not require high technology so that the investment costs are relatively cheap.

Castor oil is also used for hair oil and massage oil. Castor oil packaging is made more practical to make it easier for users. Castor oil can be found in modern markets or in stalls. Utilization of castor oil has provided good opportunities in the field of work. When planting jatropha trees until harvesting, energy is needed. Likewise, when plants are processed into oil, of course, it requires experts to make it. Not to mention the attractive packaging. It definitely takes skilled hands to package it.

The use of a lot of castor oil in addition to having a positive impact will of course also have an unfavorable impact on the community. Write your opinion about the use of castor plants. Your writing can contain benefits, economic activities that can be carried out, the impact of excessive use and solutions.

It turns out that castor oil has a lot of benefits.

Now answer the following questions!

1. Explain the benefits of the castor plant!

2. What economic activities can be done with the existence of castor plants?

3. Write down the impact if the jatropha plant is overused!

4. What efforts are being made to maintain the sustainability of the Jatropha plant!

Do it in your notebook, after finishing take the photo and send it to the teacher!

Great child, without feeling today’s learning is over. But tomorrow we will learn something even more exciting!

The next material is: Fractional estimation and extracting information from non-fiction texts. Please read the material first in the link below!

Get ready for tomorrow’s activities!

Don’t forget to say thank you to parents who have accompanied learning from home today!
