sAddition &

Subtraction

Regrouping Regrouping is the process used in addition and

subtraction that most of us remember being known as "carry over” and “borrowing”.

In addition, for example, a problem such as 19 + 3 would require us to "carry" 1 from the ones place (because 9 +3 =12) to the tens place. Since this numeral really represents the number 10, it's more appropriate to say we‘re regrouping it by putting those ten ones into one ten.

How To Teach Problem Sums To Your ChildSkill 1: Vocabulary

A child might face difficulty because he or she cannot understand the context of a word in problem sum questions.

E.g. “Mr Lim bought some books for his students. A total of 100 books were bought for boys. Girls have 20 more books than boys. What are the total books that Mr Lim bought?”

A child with a weak vocabulary may not understand the context of how the word is used. If your child suffers from this problem, you will first need to broaden their vocabulary and improve their comprehension before going into the actual problem sums.

How To Teach Problem Sums To Your Child

Skill 2: Comparative adjectives

Problem sums use many comparative adjectives that describe mathematical relationships. When a child doesn’t understand these comparative adjectives, he or she will use the wrong formula in their problem solving.

E.g.

“more than”“less than”“equals to”“has fewer than”“has more than”

How To Teach Problem Sums To Your ChildSkill 3: Understand numerical process

A third underlying skill to solving problem sums is to know which numbers to use first and what calculations to apply to them (add, subtract, multiply or divide). The best way to develop such logical thinking in numerical processes is to use the Singapore math model method.

This method uses visual representation to replace abstract numbers and variables. By using models, children can easily see which numbers should be used and how they should be used.
