Place value is much more important and includes learning the counting sequence. After many days using the usuall manipulatives, I print a sheet with three columns and 10 rows. the columns are colored left-right red-blue and green. the kids use unit blocks, tenbars, and hundredflats to build the quantity then write the number in the correct column. We do start with zero because we can't count nothing but we need a way to indicate that there is nothing and that 10 means one set/bar of ten and nothing left over. <br /><br /> It's hard to explain in writing but 4yr olds grasp the concept of place value quickly and can't wait to complete their own "booklet of numbers".<br /><br />then I present another sheet with six columns and 10 rows repeating the original three colors and separating the six columns into two sets of three columns with a good size comma. There is discussion about the new sheet and how it differs from the first. Then I use models of the new larger quantities. The kids are fasinated by the new sizes to represent the new place values. After exploring numbers from one unit through 999,999 I encourage the kids to tell me what the next sheet would look like and how big a one million unit block would be etc. We do not write these new numbers at this point. <br /><br />Using just three colors (and commas) to represent place value is much easier for the kids to grasp and remember rather than using the rainbow as some do. with older kids that can draw a cube, keep the colors till place value is firm then use only the cube, flat, and bar if still needed<br />Annehttps://www.blogger.com/profile/01350486024183735129noreply@blogger.comtag:blogger.com,1999:blog-1211816181462109845.post-43993535778375143212016-09-13T12:37:02.996-04:002016-09-13T12:37:02.996-04:00We just adopted a new math series that uses the ve...We just adopted a new math series that uses the vertical number chart.

The whole value of a positional system (ones column, tens column etc.) is overlooked in this presentation and the value and utility of zero is painfully underplayed. From a first look, at least, this seems like a simple case of organizational inertia. <br /><br />Even Tricia's much improved 0-99 chart has the numbers justified, specifically, centred within each box. This makes good artistic sense, but numbers are not justified this way, because it obscures the number of hundreds, tens, and ones in a 3 digit number. The numbers should be (as numbers always are) right justified, as in <br />http://static.eastpole.ca/patterns-100.pdf<br /><br />Thanks for bringing the issue up, Tricia!

You can use either version, just start counting at the bottom and put the greater numbers up higher.<br /><br />For more fun with a hundred chart, check my blog post <a href="http://wp.me/p2GNt-so" rel="nofollow">30+ Things to Do with a Hundred Chart</a>.

Unfortunately, the hundred chart is used in our curriculum and reporting (Ontario, Canada), and I don't want to confuse the children by using both...
