[quote=Anonymous]Side question… if you do the 30+50 and the 5+1 method, how do you explain what happens on the next problem when the sum of the two ones-place digits exceeds nine? 37 + 58 = 30 + 50 = 80 7 + 8 = 15 It seems to me that now you’re back to explaining the same principle as moving that little 1 up to the tens column. Although I agree with PP that learning different ways to see problems helps solidify a deeper understanding.[/quote]
