    Where to start

    The Dimensions Math 7 is primarily pre-algebra, and the Dimensions Math 8 is primarily Algebra 1.

    Where to start

    What about 8th Grade math? Pre Algebra or whatever you offer for 8th Grade. Theresa

    Where to start

    Singporemath.com does not sell high school math. We are no longer restocking the high school science we sell, since some titles are going out of print.

    Primary vs Dimensions

    Dimensions Math does have some logic type of problems as challenges in the workbook. Content is different, of course, we can't use the same content as a different publisher. Approach is similar. I would say that Dimensions Math is a bit more challenging than Primary Math. Perhaps easier to teach because of the delivery.

    What comes next?

    Geometry with proofs, if you want proofs. And there is a some geometry Dimensions Math does not include, even if you don't, such as secants, tangents, arcs, chords, angles and segments in a circle, constructions and loci. Vectors. Transformations. Symmetry of plane figures. Some geometry texts do include a little trigonometry, but that can wait.

    What comes next?

    Jenny, I have a question about this, if you don't mind: Dimensions Math 7 and 8 already do quite a bit of Geometry, while other texts don't - they concentrate on Algebra, then they have a whole separate year of Geometry. There is a Prentice Hall series that seems to be like that, for example. So my question is, how much of what you call "high school geometry" would a DM7+DM8 student know already? And what difference would you see between a high school Algebra 2 course, and a college text for intermediate algebra? Thank you!!

    Primary vs Dimensions

    Hi! We have previously used Primary 1 & 2 and loved it so much I’ve never even considered looking at other options. Then I noticed Dimensions was available. I’m trying to decide whether to stick with what I know works or switch to something new. There weren’t as many sample pages available to look at for Primary 3A & 3B. I saw lots of logic type problems in Dimensions 3. Does Primary have the same logic problems? Is the content different or just the delivery? The Dimensions sample seemed a little more difficult but maybe it was just the particular pages I saw.

    PM US 6 vs Dimensions 6

    Dimensions Math 7 is pre-algebra. Any topic in pre-algebra, even if you use a different program, will more than likely thoroughly review any pre-algebra topics that might have been introduced in any US 6th grade program. PM 6 US edition may be a lot of review, but it is also a lot of depth and has more challenging problems, which does promote mathematical thinking. I don't think using it will not permit success in a pre-algebra text. It just won't have integers or simple one-step algebraic equations. You may find Dimensions Math 6 is a lot of review, as well, since Primary Math is generally ahead of US math in grade 5. Dimensions Math 6 was written just for the US, and had to satisfy US 6th grade requirements, and therefore does repeat a lot from PM 5, as well as introducing at the required topics involving integers and simple equations (which you will get again in pre-algebra). So I don't think you will go wrong with either choice. Look at the sample pages and see what you like best.

    Intensive Practice 5A US edition, pg. 91, #47

    Draw a bar with 2 units for children and under that one with 1 unit for adults. That is the situation at the end. Add 24 to the 2-unit children bar, that is how many were there before the 25 left. Before the adults left, there were twice as many as children. So make the adult bar twice as long as the children bar is now, which is 2 units + 25. So the adult bar has to be 4 units + 25 + 25. It was 1 unit. So now you know that 3 units + 50 is 530. Now you can find the value of 1 of the units and solve the problem.

    I’m guessing everyone is stumped by this one? 😬
  15. Thank you, so easy after you explain it.
  16. Twice as many adults as children attended a violin concert. During the intermission, 530 adults and 25 children left the concert hall. The number of children remaining in the hall became twice as many as the number of adults remaining in the hall. How many people attended the violin concert?

    After Primary Math 6B

    New Elementary Math is about 20 years old. It is more challenging, but some components are out of print, like the Teacher's Manual that has solutions and answers to the end of the chapter challengers.

    PM US 6 vs Dimensions 6

    My 5th grade son has used Primary Math US since 1B and will finish 5B this summer. I have been happy with the program. I can’t determine whether to continue in 6th grade with PM US 6 which is mostly review or change to Dimensions Math 6 which introduces new topics. The intent is to complete pre-algebra in 7th grade (though I haven’t settled yet on which curriculum to use for that). Which is a better preparation for pre-algebra? Will he be missing anything by spending 6th grade on mostly review (using PM) versus starting to learn new concepts with Dimensions? Anything else I need to consider in making this decision? Thanks for any input provided

    It is sort of misplaced, since it is an inverse proportion.

    Standards vs. US

    Hi, we are toward the end of our first year homeschooling and have loved the 4A & 4B US edition of Primary Mathematics. So, I am starting to think of our next level in math and came back to the website. I noticed the Standards edition covers a number of additional topics (mostly year 6) compared to the US edition, and I started reading through a number of posts on this issue. The above post seems to capture in a couple sentences why the difference. Other than this is how it is done in Singapore (or US), do you have any additional thoughts on the pros/cons of the US vs. Standards editions? Any logical/developmental/ or other reasons why one might be preferred over the other? Thanks!
  26. For question 1e the answer we came up with is 1/2. But the answer key has 1/6. Can someone explain the discrepancy? Because according to the formula, P(AorB)=P(A) +P(B), so since both cards occupy half of the space, not drawing both on the first try should be half. I can't come up with 1/6 as the key indicated. Someone please show the steps? Thanks! We seem to have more discrepancies with the answer key on the probability section than anywhere else.
