Hi, I found a few different math programs/books like:
DVD set Charlotte Mason’s Living Math: A Guided Journey
Mathematics: An Instrument for Living Teaching
Mathematics: A Human Endeavor, Elementary Algebra and Geometry
Your Business Math
Math lessons for a living education
Which of those would be advisable for the beginning (13 & 15 yo but new to CM)? Or do you have other suggestions? How do you practise math? Do you use workbooks?
Many Blessings!
