Creating a Sum across worksheets. This is also an inter_active link. If a number changes on one worksheet, the sheet with the summary formula will also be updated. If a worksheet is inserted between worksheets in the sum, the sum will automatically be updated. Some of the disadvantages of this method are that all of the linked cells must be in the same location on all worksheets. Also, you can only sum one cell at a time (although you can copy the formula to other cells in the summary worksheet.) Using group mode to create identical spreadsheets will help when using the sum function across worksheets. This method is also limited to within a workbook and cannot be done across workbooks.
In choosing a worksheet, it is important to review the source and check the material. Ensure that the material and answers are accurate. Evaluate the worksheet by completing it yourself. The worksheet should provide information clearly and accurately. Make sure it is exactly what you need to homeschool your child.
