  2. Plans to discontinue any series?

    Good news. Thank you!
  3. Plans to discontinue any series?

    There are no current plans to discontinue Primary Mathematics. It is still a good series.
  4. Are there plans to discontinue any series with the addition of Dimensions K-3?
  5. Earlier
  6. Digital Resources

    Thanks, Jenny!
  7. Digital Resources

    There are no online resources for these.
  8. Digital Resources

    What kind of online resources are available for Dimensions 6 - 8?
  9. 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?
  10. Hi, I'm needing workbook 6B page 137 #5a,b explained to me. I am overthinking this and can't figure it out. Thanks in advance.
  11. 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
  12. I have a fourth grader who does well at math in public school. I was looking at the samples in the Challenging word problems Book 4 and realized he doesn't know bar diagramming at all. We are new to Singapore math books. Although my child solved the problems without using the diagrams. I see the obvious benefits of bar diagramming and would for him to pick up this skill. What book in the Primary math series introduces bar diagramming? Alternately is there a separate resource to learn just bar diagramming?
  13. 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.
  14. Whats next after US ed 6B?

    I want to clarify because there is a lot of discussion related to Standard ed. but my kids use US Edition. Should my daughter continue to Dimensions 7A following completion of US ed 6B? Some mention going into Dimensions 7A following 5B Stand Ed so I want to make sure I understand the differences. Sounds like the Elementary math is especially challenging and not complete in its resources. Any other options or insights?
  15. TEKS

    With whom? Yes, it is just an informal document. Not carefully reviewed, but a start.
  16. TEKS

    Would it be possible to share this resource?
  17. 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.
  18. Hello, I was looking to buy standard ed for grade 1 and than I noticed the announcement that there is new series coming this spring. Can you provide more information? I have waited all this time and didnt want to rush now after looking at this banner. Should I wait for new series? Any info on how different would this be? Thanks,
  19. 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.
  20. Primary math 6 vs. Dimensions Math 6

    Thank you Jenny! Though I can see the table of contents, I just don't remember what is considered pre-algebra and what is algebra. I want my daughter to begin algebra in two years (so she can qualify for a certain science class). Does Dimensions Math 7 cover mostly pre-algebra or algebra?

  22. Workbook Help

    My school is currently using the Primary Mathematics US Edition. The frustration is from the workbooks. The pages are not perforated therefore very difficult to tear out and grade. Our school likes to send papers home with the students in effort to keep parents informed on the child's progress. It also is very difficult to collect 20+ books to grade. Does anyone know if there is a plan in the near future to print the books with perforated options? This seems small but it is a huge problem for our school. Alice
  23. 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.
  24. The price of tickets for a musical is as follows: Adult $54 Child. $36 30 more adult tickets than child tickets were sold at the end of a certain day. If a total of $9000 was collected for that day, how many adults and children attended the musical? I would love it if someone could help me solve this problem, in particular I'd love to see how to show using bar diagrams. Greatly appreciated!!
  25. 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).
  26. Place value tiles

    We are planning to make our own place value tiles for each student. The colors in the book are different from the colors you can buy. We are thinking that it makes sense to match the colors used in the textbook, which are blue-ones, pink-tens, green-hundreds. What are the colors in the textbook for 10,000 and 100,000. Do others make their own and match to the colors the textbook uses?
  27. Test 5A Unit 4 Test 5B

    Draw a bar, divide it into 5 units, indicate that the last 2 units are red. Add a part to the bar on the right, label it as 12. No, the last 2 units plus the 12 is equal to 2/3 of all her hairpins. Therefore, the first 3 units is equal to 1/3 of all her hairpins. Since 3 units have to equal 1/3, then 6 units have to equal 2/3, but you have 2 units and 12. Therefore, the 12 must be 4 units of the same size as you started with. Each unit is therefore 12 div 4 = 3. She started out with 5 units. 5 x 3 = 15
