The Cotter Tens Fractal helps the child experience our place-value system concretely by representing how our number system is constructed with tens. It starts with ten small colored equilateral triangles arranged in the shape of a larger equilateral triangle. This is the Ten Triangle. Ten of these triangles arranged in the same pattern form the Hundred Triangle. And ten of the Hundred Triangles form the Cotter Tens Fractal.
We would love to see your completed work! If you’d like us to post your Cotter Tens Fractal here for others to admire, please send your photos to info@RightStartMath.com.
Math journals are used in a variety of places in the program. If you need more, here you go!
Both second edition and first edition manuals have appendix pages in the back of the book that need to be printed for various lessons. Second edition (RS2) has the pages already printed and available in the Book Bundles. First edition (RS1) has Levels A and B Appendices packet available. For your ease, you may also download the files and print them from a pdf.
When we find errors or needed corrections, we post them here. When needed, we update monthly. To check if your book has a correction, do the following:
- Find your manual or worksheet’s print date. This is found at the bottom of the second page of your book directly under the ISBN number.
- Click on the appropriate button below and note the date at the top of the pdf. If the date of your book is newer than the pdf page, there are no corrections. If the date of the pdf is more recent that the print date, or the pdf date is updated since you last looked, there are corrections to be made.
- In each file, the Lesson corrections are first followed by the Worksheet and Appendix corrections. If you are looking for a specific lesson or worksheet, all you need to do is look down the first column. If you are looking to see if ANY correction was made since your manual or worksheets were printed, search for any correction date past your print date. Any date listed that is prior to your book’s print date will be included in your book.
If you find a new error in your manual or worksheet that is not listed, we want to know. Please email us so we can correct it.
