Daniel from Englefield Infant School had a go at this challenge. First he tried 8 and 3 on the left, as the question suggested:8+3=1+2+8
I like the way you have written these in a very logical order, Daniel. Well done! Next, Daniel tried 10 and 9 on the left side of the balance:10+9=1+8+10
Fantastic! Izzy from Tonbridge Grammar School reminds us that:Whatever the sum of numbers of weights on one side add up to has to be equal with the mass of weights on the other.
Thank you to you both.
