I don't normally review or recommend curriculum. It seems strange to say it, but actual curriculum products have been a tiny part of our homeschooling journey. There's one resource I did use for all six of my homeschool graduates all the way from Year 1 to Year 10. It was super-affordable, Australian, took only minutes to complete each day, had Teacher's Guides (Primary and Secondary) with all the answers so I could check answers quickly, and covered all the basic maths skills.
We complimented our studies of Maths with lessons in Khan Academy, other free video Maths lessons online, games, sitting and explaining concepts a few different ways, and developing handwritten worksheets, and manipulatives such as rods, blocks, counters and rulers. Mostly, though, we simply used these books, and I'll be using these books again, with Zeah from next year, when she is five.
Take a look at the New Wave Mental books here.
