I have been using Signpost maths since I began my homeschooling journey.
The advantages are: the topics are linked with outcomes, easy to understand, explanations on top of the page and answers available.
However, I feel each topic is spread out all over the book. I prefer to master on one topic and then move on to the next.
That’s why I use Math U See program. It is a mastery based program. Each level is based on one type of math operation.
Therefore, this program along with Signpost Maths help me to make sure that my kids are learning the way I want them and also they are not missing on any outcomes needed to be covered.
