Yearly Overview
You can find the yearly overview for this year at the Elementary Student Page at this address:
http://my.ofs.edu.sg/user/ele/students/
For a more detailed overview of each block, please refer to the Scope and Sequence documents. You will have to log-in to the OFS website under your child’s name and password to retrieve this document. This could give you advanced notifications on what topics are to be covered as well as the learning objectives under each topic.
Math Homework
Math homework is given to students on Monday and should be returned to school on Friday of the same week, or earlier if completed. The children will discuss/mark the homework in class on Friday. Math homework is set from the Math Weekly Revision 4A and 4B textbooks.
Homework Online
Homework is set by the Math teacher and placed online.
Please follow the steps below to assist you in finding your child’s Math homework. The children have practiced finding their homework online in class, so therefore, they should be able to help you as well.
- Go to www.ofs.edu.sg
- Log in using your child’s username and password.
- Click on Math
- Click on Homework
- Look for this week and see what pages/handouts you have to complete. At times, there maybe a handout that requires you to print it at home.
If there is a handout that requires completion, remember to click on “Resources” and print out any extra handout.
During Math homework sessions, please encourage your child to work out an answer using his/her own strategies. Be patient with their trial and errors attempts and encourage them to try again. If your child asks for help, here are some ways to respond that will encourage him/her to persist in her/her efforts:
- What are you trying to find out?
- Explain the situation to me in your own words
- What have you tried so far?
- What did you learn from those tries?
- How else might you start?
- What is the most important information in the problem?
- How can you keep track of your findings-will a picture, chart or table help you?
- How you thought about trying…?
The students are encouraged to not only memorize facts but to understand their relationships and be able to explain and show how they came up with a solution. They soon realize that there may be more to one way to approach a problem, or more than one answer. Mathematics instruction is not just about paper and pencil computation but about helping children become flexible thinkers who are able to apply their ideas and skills to a range of problem-solving activities.
Kindly see your child’s Math teacher if you have any questions.
Regards,
Grade 4 teachers.
