Mimosa's answer to Dan's Primary 5 Maths Whole Numbers Singapore question.
Thanks Mimosa. It starts to make sense after seeing your model. The precise model makes the understanding easier.
Would you know how would the below model looks like? I can’t figure it out why is this the approach with teacher’s working. My kid did not manage to copy the model. Thks
Teacher working shown as
2unit = 70 - (10 x 4) = 30
1unit = 30 / 2 = 15
Fred = 15 + 10
