Dear Parents
I wish to highlight some key points/ mistakes made by some children in 2 Thinker, so that you know what to look out for when you guide them in their work.
Word Problems: Work with the numbers given in the word problem. Method marks are still awarded (in a test) if your child is able to show understanding of the goal of the problem if he/ she answers the blank within the final statement correctly. However, let's reinforce the good habit of working with the numbers given within the problem.
Commonly-made mistakes
1) Alignment of numbers
The children are expected to complete the computation in the ones place first, then the tens place. In the above example, the child has written her computation of the ones in the tens place. At 8 years old, I know that some children have yet to develop their motor skills in writing numbers with ease. However, that should not be an excuse for the mis-alignment in answers.
2) Transfer error
Refer to the 2 examples of transfer errors. Such mistake could result in loss of marks.
Other possible mistakes (not noted in P2Thinker yet...)
3) Forgetting to put the Mathematical sign (addition/ subtraction sign)
4) Ignoring the function of the Mathematical sign (is addition but child subtracts when solving the sum)
------------------------------------------------------------------------------------------
I can tell that most children have tried their best to ensure that the answers are in the respective places. I'm not looking out for font-print neatness, but a child's best in all that he/she does. We must be strict on the placement of working so that the children will be consistent in the way they do the standing algorithm (vertical working). Essential when they deal with greater numbers in upper primary.
With neatness in alignment, children are less likely to commit careless mistakes in computation. I hope to work closely with you to monitor your child's assignments.
