So far it's ok. Only in review thus far so very easy for my kindergarteners. They don't ever want to do side B saying they already did it so I have started mixing and matching lessons. They catch on quick and get bored easy so I have to keep things interesting.
I purchased the Saxon Math 1 the summer before my daughter going into Kindergarden at the advice of a friend. We do two pages a day, just the front portion, unless she gets stuck on a question. Then I use the back of the page to go over the topic, and then we move on.
Saxon Math home kits/books are fantastic. They qualify for "blended" math in home school programs, they are "spiral learning" style so the kids learn something new and review something old making sure they don't forget. This program keeps you slightly ahead of provincial grade. Both of my kids love it. One part with calendar, one part hands on manipulative, and one part written practice. It covers all learning styles and works very well.
