  1. Whats next after US ed 6B?

    Don't worry about the label. It just means that some things were added to meet the topic requirements, and a few things moved. Like using the absolute value symbol. They still include material in advance of Common Core. They still include all the content of the Discovering Mathematics from Singapore they are based on. You can see table of contents of any of our books by clicking on the image or name of the book, and then clicking on the tab that says Contents_Sample. For 7A: http://www.singaporemath.com/Dimensions_Math_Workbook_7A_p/dmw7a.htm for 7B: http://www.singaporemath.com/Dimensions_Math_Workbook_7B_p/dmw7b.htm
  2. Grades 9-12 Math Curriculum

    There was a bit added to make it more algebra 1 ish, but you will get that in algebra 2 as if new. The quadratic formula was added, and a bit more on integers. But also a bit more on probability and data analysis to meet Common Core requirements. But that is not something that would affect algebra 2 readiness. But yes, algebra 2 has a lot of repetition and reteaching of things that are briefly introduced in a typical algebra 1 text in anticipation.
  3. Tests?

    There are no published tests for Dimensions Math. There are reviews for chapters in Dimensions Math 7 and 8, or you can select problems from the supplementary workbook.
  4. Is Dimensions Math 8 Algebra I?

    It covers most of the topics in most algebra 1 texts. It is adequate preparation for algebra 2.
  5. Plans to discontinue any series?

    There are no current plans to discontinue Primary Mathematics. It is still a good series.
  6. Digital Resources

    There are no online resources for these.
  7. 6B Workbook Page 137

    For (a), probability for first toss is 12/16 and for second toss is 4/15, so 12/16 x 4/15 = 1/5 For (b), it is 4/16 x 3/15 = 1/10. Do you need further explanation?
  8. Introduction to bar diagramming

    The Process Skills books are good for that, as they have more explanation and detailed solutions. You might want to start at the 2 or 3 level. See http://www.singaporemath.com/Heuristic_and_Model_Approach_s/151.htm There are also various web sites and you tube videos others have done, but they are sort of hit and miss. But you could try https://www.mathplayground.com/thinkingblocks.html
  9. Whats next after US ed 6B?

    Yes, she can do Dimensions 7A after US edition 6B. I think she should not skip US edition 6A and 6B, it it is good. A lot of review, but wonderful problems as well, and depth added for some topics. I am not as fond of Standards edition 6, as it was a total rewrite, US math being so different at that grade level. Standards edition has some things moved down from 6 to meet some requirements in California (the topics should actually have been made easier, or more introductory, but the were not). And, area and ciricumference of a circle was added to 7. Which means no topics lost, if you wanted to do that. That is not the case with US edition, and anyway that level has a lot of good depth and good problems and covers some topics very well. New Elementary Math is quite challenging, and the Teacher's Manual is out of print, but if you can find it used, and want the challenge, your child will get a very deep understanding of math, or get frustrated with not being able to solve half of the problems, depending on your child's math abilities. And maybe yours in helping.
  10. TEKS

    With whom? Yes, it is just an informal document. Not carefully reviewed, but a start.
  11. New Singapore Math Series

    It is similar to Primary Mathematics, prior to the Common Core edition, but better..., at least for grades 1-5. It will be true to Primary Math more than to Common Core topics, though. There are periodic practices, reviews every half-semester, some challengers in the workbook. You will have to keep an eye on the web site for when samples are up. The one problem is that the Home Instructor's Guide won't be ready this year, though textbooks, workbooks, teacher guides for grade K-1 likely will be by April. The Teacher's Guide will be usable, though, by homeschoolers. There will be a Home Instructor's Guide for grades 1-5, but later.
  12. Primary math 6 vs. Dimensions Math 6

    Dimensions Math 7 is mostly pre-algebra. It might be sufficient for a science course, depending on the course. It does not cover factorization of polynomials. It would not be considered a complete high school algebra text, I don't think.
  13. Workbook Help

    Please email school@singaporemath.com
  14. Intensive Practice 5A word problem

    It is not necessary to solve all problems with bar models. By grade 5 they should be able to think logically. One issue with this problem is that two quantities are involved, price of ticket and number of people. Sometimes, a problem cannot be easily squeezed into one bar model either. You could use two bar models. But another problem with bar models sometimes is adequately showing division by grouping where you do not know the number of units. Bar models are helpful especially initially with complex word problems, to help students think logically, but are not universally applicable. That is one problem that arises from the use of bar models, the idea that all and every problem can be easily represented with them. It can be useful to start trying to draw bar models, and maybe that will lead to the idea that the child tickets and adult tickets can be be added together for 1 unit of child/adult ticket. Then, you could show that there were an as yet unknown number of child/adult tickets, a combined unit, and then 30 more of the adult tickets. Except that you would not want to bother drawing 30 units. Or, you could show one bar for children tickets, one for adult tickets that is longer, and associated the calculations below with each part. 30 more adult tickets were sold, so 30 x $54 = $1620 was made for the extra adult tickets. $9000 - $1620 = $7380 is what was made from equal amounts of child and adult tickets. A child and an adult ticket together is $54 + $36 = $90 $7380 / $90 = 82 82 children attended 82 + 30 = 112 adults attended.
  15. Place value tiles

    I have never had an issue with any differences in color. I just marked round counters. They do not use them for numbers larger than 9999, if your child does not understand place value by then there is a problem. But, they do have a picture of cards instead of discs in 5A and ten thousands is darker blue and hundred thousands yellow (arbitrary colors).
