Math: Ordinal Numbers

Dear Boys and Girls,

Let's view and learn about Ordinal Numbers.

Our Math Lesson - Subtraction

Topic: Ways To Subtract: Subtracting by regrouping into tens and ones
Introduction:
ipad application aids students to subtract within 20.

Amber: "We're not sure how ...,"

Green: "Let me show you."

Green: "We can do it too."

 Teacher explained the steps to subtract by regrouping into tens and ones.



Now it's time to let students do the same steps in groups.

Green: "We're confident!"

"We are better! Let's show our mental steps to our classmates." Excellent!

Teacher asked each group to look at their steps and explain their steps to get the answer.

Now it's time to have our individual work.

Multiplication & Division

Dear Parents,

Primary 1 Multiplication
"The emphasis is on understanding the meaning of multiplication rather than on the memorisation of multiplication facts." 2011 MOE CPDD

Meaning of Multiplication

• A whole is made up of equal parts
• Adding up the parts to find the whole
• Repeated addition
• Putting together equal groups
• Groups with equal numbers of objects

Meaning of Division

• Breaking up into equal groups
• 2 types of division situations
• Sharing - Find the number of objects in each group
• Grouping - Find the number of groups

Math foundation is important!

Dear Parents,

Can you remember Mr. Tsu's letter dated 4 Jan 2011?

"The '10,000 hour theory' posits that people who do well in Mathematics would have practised more than 10,000 hours over about 10 years of their lives as a student.

The number of hours for Math in the classroom is not enough. If your child can't do basic addition and subtraction, your child will definitely can't do the topic on Money. The accumulated topics that your child doesn't know will increase as days go by. I hope you will understand my concern.
