A DIY kid to teach my daughter how number line works and how to use it to addition and subtraction
I have made similar teaching aid for my daughter before. That is the one shown on the right (the upper paper). The intent then was to show how all the number moves along the number line. In addition, use it to assist my daughter on how to do addition / subtract of double digit with a single digit. I feel this is the fundamental of all maths operations, without getting this right, she won’t be able to progress further in maths. She will be just memorising what her maths teacher taught her without understanding.
I decided to make the 2nd version at the bottom because I realise my daughter was having difficulty to move from the upper row to the lower row (the 1st version on top). Sometimes, she forgot 1 number smaller than 11 is actually 10……. (yes it is quite disheartening for a P5 student not getting this correct 100% of the time). I gave a thought on how to improve on this yesterday and decided to make it a single row.
This number line should be sufficient because we can max borrow a “10” when doing subtraction from the immediate larger digit. Thus, the max she needs to do is “18 – 9” which she just needs to move her finger from 18 9 steps to the left and end up the number 9.
On top of this teaching aid I created, I will make it a habit to let her do 10 addition & subtraction questions daily with this aid. Something just takes time to get the result, no matter how much resources we put in. I guess in this case, parents’s love and patience is the most critical resources any dyslexic kid needs the most.
After this numbering one, I will move to fraction next week. I will do the same and see how I can assist my daughter to grab this concept. Fraction will be a challenge for her because it involves another concept of smallest common multiple when she performs addition or subtraction of fractions……. let me think about it and share more next week.
