Remainder concept problem sums often contain the word “remainder” or ask about the total amount of something given the remainder. Most of the time, remainder concept questions test the knowledge of fractions. Mrs Lim had some chocolates. She gave 178 chocolates to her neighbour and 2/5 of the remainder to her daughter. With the remaining chocolates...
Repeated Identity concept problem sums commonly feature one unknown or variable as a point of reference for other unknowns. Hence, the units method is used to solve these problem sums. Alice, Betty, Clara and Denise shared $168. Denise received 1/7 of the total amount of money received by Alice, Clara and Betty. Alice received 3/4 of the total amou...
Equal Concept problem sums compare fractions or percentages from different unknowns, but which represent equal amounts.
There are four different transfer type problem sums, and it can be difficult for kids to determine which transfer type is being used in the question. The simplest way to solve transfer type problem sums is to draw models. However, children who are more advanced can try using algebra and simultaneous equations to derive the answer. In an external tr...
Internal transfer concept problem sums refers to questions where an amount is subtracted from one unknown and added to another, so the total amount in question remains unchanged. It is also known as the Constant Total concept. Leon and his sister Lily have a total of 120 crayons. If Leon gives Lily 5 crayons, Lily will have nine times as many crayo...
Pattern concept problem sums are among the most challenging, as they require students to recognize varying number patterns that may involve more than one arithmetic operation. Study the pattern below: Pattern 1 Pattern 2 Pattern 3 (a) Complete the table below. Here, you will need to find the relation between the pattern number and the number of mat...
The part-whole concept is one of the main concepts for problem sums, and forms the basis for other concepts mentioned here. Read more about it in our detailed post about the Singapore math model method.
Simultaneous concept problem sums are a precursor to simultaneous equations in algebra, where abstract variables are represented using objects. While simultaneous concept questions can be solved using the model method, they are the best for introducing your child to algebraic methods. 3 files and 2 books cost $60. 2 files and 3 books cost $70. Find...
Gap concept problem sums are based on the difference between one variable and another. They can be solved using the ever-useful model method, or by arithmetic. Joe’s father had given Joe and Kevin an equal amount of money. Joe spent $20 each day and Kevin spent $25 each day. When Joe had $157 left, Kevin had $82 left. How much did Kevin receive? 1....
