Have you ever noticed students that are perfectly capable of counting well past 20 get stuck writing past 10 on a traditional Hundred(s) Chart? That happens because the last number in the first row is 10-ten, especially at the end of a row, seems whole and complete-which creates a sort of big red stop sign in their minds.
This chart was not only designed horizontally to make individual table cells larger (making it easier for little hands to write in) but is a 10x11 chart that is designed to begin with the number zero.
Beginning with zero serves two purposes:
1. it makes the last number in row one a 9-automatically removing one major obstacle as the majority of children will instantly know that the number that should follow is 10 and
2. as children continue writing numbers they will notice a distinct pattern forming; every number ending in 0 lines up under zero, all numbers ending in 1 create their own column under one and so on and so forth (another nice things about this feature is that it creates the perfect environment for self correction).
Place Value Guides to help them make sense of numeric values and helps students avoid missing/skipping digits.
