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

Teacher's working seems to match this model which is indeed easier to draw and understand. Cheers!
