How to teach angles?

[cimman]

at lower primary, the angles are drawn to scale, so measuring it is an option. At higher primary, the angles are not drawn to scale, so measuring it, is not an option. The angles are derived through logical deduction.

Hmm...This is something important to know. Thank you for sharing. I am really worried as my DD may require a lot of training/coaching before she can master this part. sigh.....

Introduced the topic "angles" to DD two days ago. I used the paper, protector and ruler. She seems to be comfortable with the ruler.


Guessing method or prediction method…Hmmmm…most of the times she guessed correctly but sometimes…wrong. May be she needs time. I asked her to guess and write down first and then measure using the ruler. Seems to be fine.

She had problem in using the protector. She could not align the lines properly. Must test after a week again.

Thank you for all your feedback.

Complex figure where several lines overlap with each other - something like that. Anyway my DD is fine with that now as she went thro' several similar questions.

The question was posted last year. Thank you.
