Our Children should be doing Algebra & Geometry much earlier. Geometry. A Circle. 360 degrees. Bust that down the middle. 180 degrees. Diameter. Same as half.
If it was a dollar bill, it would be 50 cents. Half is Half no matter what you dealing with. Only thing, word name changes. Bust that half down the middle again, you have 90 degrees. If it was a dollar, it would be 25 cents. Why in the world do we waste so much time, & not take our children to higher levels of math, just because schools go at a certain pace?
Never underestimate the brilliance of our children.
Rock that Circle & Dollar Bill Technique. See how your children dig it.
