How Singapore Math-Dimensions online grading worksWhat Nicole the Math Lady Says

Great Fit If Your Student:
Thrives when challenged with problems that encourage critical thinking
Learns well through visual models and problem-solving strategies
Retains concepts well without a lot of repetition
Not ideal if your student prefers to be shown a single way to solve problems
After taking advantage of several days of the free trial, my son can already tell that the rest of the year will be much better. Thank you for being a game changer for us. Math has become much less perplexing and is positive again.

Frequently Asked Questions
Some of the key features of Singapore Math-Dimensions include concrete/pictorial/abstract progression, number bonds, bar modeling and mental math.
Today, there are a few different series of books that use the Singapore Math method, with Singapore Math-Dimensions being a very popular choice for both the homeschool and classroom setting.
You can read more about the Singapore Math method.
- are visual learners.
- like to start at the conceptual level.
- enjoy creative problem-solving.
- are logical.
- tend to be independent thinkers.
Singapore Math-Dimensions might not be the best fit for students who need repetition, prefer a straight-forward approach, get distracted by images, prefer to stick to one strategy and tend to process things in a set sequential way.
Video Lessons- 1st through 5th
Online Grading- 2nd through 5th
In a second video, she will work through some of the problems of the Do section but will prompt the student to complete remaining problems.
All of the problems in the Workbook can be checked for accuracy in our online grading system.
- Textbook A & B
- Workbook A & B
- Tests A & B
In addition to the student books, we suggest the parent/teacher also have access to either the Home Instructor's Guide or the Teacher's Guide.
They both serve the same purpose but are different enough that most people have a preference for one over the other. You can read more about the two workbook options. Finally, there are manipulatives that are strongly suggested (though not required) for each course. You can see the list of suggested manipulatives.
Example: The books needed for Singapore Math-Dimensions Third Grade course include:
- 3A Textbook
- 3B Textbook
- 3A Workbook
- 3B Workbook
- 3A Tests
- 3B Tests
- 3A Home Instructor's Guide or Teacher's Guide
- 3B Home Instructor's Guide or Teacher's Guide
- Suggested manipulatives
Please note- Singapore Math-Dimensions is divided into two parts for every grade: A and B. To gain the full content of the course, both parts should be completed.
- Go to the Singapore Math-Dimensions placement tests.
- Select the test based on the level your student completed with their last curriculum.
- 1A = the first half of First Grade,
1B = the second half of First Grade,
2A = the first half of Second Grade, etc.
- 1A = the first half of First Grade,
- Print (answers are included in the same PDF.)
- Give your student the assessment.
- If your student does well, they are ready for the next level of Singapore Math-Dimensions.
EXAMPLE 1: A student completed the entire Kindergarten Abeka Math curriculum. The student takes the Singapore KB placement test and misses just one problem. The student should be successfully ready for Singapore 1A.
EXAMPLE 2: A student completed some of Saxon's Math 2. The student takes the Singapore 2A placement test but misses several problems. The student then takes the 1B placement test and gets a perfect score. The student should be successfully ready for Singapore 2A.
Please note that many homeschool reviewers suggest starting Singapore Math-Dimensions by 3rd Grade — if you are switching later, the placement test will show you exactly where to begin.
- Ask yourself why you want to switch? If your student's current math curriculum is not a good fit, then, yes, you should consider switching. But, if it's working well, then you might want to consider that a victory and leave it alone. (Switching curriculum is one of the biggest reasons of math gaps.)
- Stop to identify what's not working about your current math curriculum. Now ask yourself if Singapore Math-Dimensions will create the same issue or solve that problem.
- For instance, if Horizons is not working because your student finds the images distracting, then Dimensions likely won't be a good option because it is also colorful and filled with images.
- On the other hand, if your student is doing Saxon and they cannot handle the heavy review approach, then changing to Dimensions with its mastery approach might be a good option.
- Consider where your student is in their math journey and assess whether it's wise to switch them at this time. Many reviewers suggest starting Dimensions by 3rd grade, though the publisher (Singapore Math Inc.) supports later entry using their placement tests. Additionally, while the Dimensions series itself runs from Pre-K through 8th grade, our video lessons currently cover 1st through 5th grade.
- If you decide to make a switch, always start with the placement test. No two math curriculums line up perfectly and it's important to start your student in the correct book. You can find the placement test for Dimensions. And, keep in mind, it's more than okay to go back a grade level. If the goal of switching curriculums is to create a better math experience for your student, then you increase the chances of that happening if the new math curriculum meets your student where they are.
- Lastly, it is important to note that picking up in the middle of Singapore Math-Dimensions' scope and sequence might prove challenging for many students. If at all possible (and you have not done so already,) we would suggest getting your hands on the Singapore Math-Dimensions curriculum to check it out directly. You can also watch some of Nicole's video lessons here to get a better understanding of the content. If it looks like it would be a great fit for your kiddo, you could consider beginning with their 3rd grade (or even earlier) to ensure you are not skipping over pertinent vocab, structure, etc.
