Math for Homeschoolers Why do we teach math? Math is everywhere! Whether your child will grow up to be a mechanical engineer or a stay at home mom, kids need to learn their math facts. Basic Math Skills necessary for life: adding/subtracting multiplying/dividing measuring to the nearest 32nd of an inch, or millimeter (English and metrics) Basic geometry: shapes and solid figures (cone, sphere, prism) finding area and perimeter. My Opinion: God is a mathematician! Anything that is important to Him is important to us and therefore worthy to teach to our children.
