A Bottom-Up Hundred Chart?
Putting a twist on a popular mathematical tool, this collection
of activities shows how putting a number 1 in the bottom-left cell and a 100 in
the top-right cell can better support student reasoning.
This is a great idea, especially for our students with dyslexia who have difficulties with directionality. Thank you!
Neat Idea! I have used Hundred Charts with great results for years. Marilyn Burns also suggests some weird, but awesome activities that can be used in a similar fashion. Yours seems to be more conceptual, though.
I have found that 0-99 charts (as opposed to 1-100) can also be used to illustrate different and useful concepts. I always keep copies (charts) of both types--depending on what I am demonstrating. One strength of the 0-99 chart is that the "bottom" row shows the "basic" numbers 0-9 and the next row (tens) shows the basics written with a (1) in front. Similarly--on to the 20s, 30s, etc. In this way, all the, i.e., 10s groupings are all on the same row allowing children to locate and read certain numbers more readily. There are many advantages to using both formats for discovering patterns and realtionships, and the bottom up shows a lot of promise! Thanks for your always useful and inspiring articles!
