The worksheets I selected to Jaimie/Livvie to do-I saw might be hard for those 2- I already had marked Jamie as Grade B from a (2nd grade) worksheet, & I had marked on one of worksheet from Livvie as Grade A- that is a 4th Grade worksheet.
On this first page math, you draw some dots to this-a dot in each square(of course some squares to be left blank here).
And on this you write/type only a capital letter to each problem to represent a number (that each shows right next to the capital letters), hope this is enough instructions here. And I think I put the math pages where you might can find them.
