rounding up number

LI:To solve problems by partnering numbers.

This week for maths we had to make a DLO (Digital Learning Object) to show how we could solve equations by partnering numbers.I learned it by having examples of how we could solve the equations for example 6+87=93 how will i will show you how.87+3=90 we get the three from 6 so 6-3=3 then 90+3=93.
