Both lower_level_thinking worksheets and too many (even high quality) worksheets can hold students back by not providing stimulus and challenge. Studies have shown for years (just do a Google search!) that children learn best through active involvement and real_life experiences. Virtually every teacher knows that children learn to read by being exposed to books and by being read to, NOT by completing worksheets. The same applies to all areas of learning.
Easy Worksheet Management _ Right_click on any sheet tab (Sheet1, Sheet2, etc.) for a shortcut menu of worksheet options. This is a quick way to rename, delete, add, apply colors to worksheet tabs, copy, and more. By the way, you can also rename a worksheet by double_clicking on any sheet tab (Sheet1, Sheet2, etc.) to highlight the sheet name. Type a new name and press [Enter]. Tip: avoid ALL CAPS which increases the width of the sheet name and decreases how many worksheets can be displayed in one view.
