Mathematics and Science
Math is supposed to be pure, except when it isn't. Writing-off commonalities in numbers that are far to numerous to be random as mere coincidence is startlingly thickheaded.
Math and Science have always been my favorite subjects as a student.
My kids are usually interested when they see me working on some problem and use math in a practical way. They have been shown several times how useful memorizing math formulas are and doing things like: accurately calculating the height of a tree in my head or measuring how far away an object is using geometry.
I have taken a special interest in making sure that they know geometry, especially what is usually referred to as "Sacred Geometry". This stuff is called "sacred" for a reason. Don't dismiss its value to cultures because "it's just math". Many of the formulas found in sacred geometry were hidden for millennia to keep secret the techniques to maintain some advantage over others.
My kids are in early elementary school and know how to derive any shape they need using a compass and ruler. They know how to do things like bisect a line and create equally sided polygons. When I was their age, I didn't know any of this and struggled fiercely with math until I was in High School when it clicked and finally became easy for me to understand.
When they reach the time in school when they need actually perform it, they will have the tools at their disposal because they have played math games and drawn shapes with dad for years and already know the formulas.
My children understand that cooking and baking are chemistry and formulas help them make anything they are trying to concoct. (like slime)
Math and science are more appealing to them when they know they are critical tools to survive.
Did you know what the Flower of Life, Metatron's Cube, 3-4-5 Right Triangles, Phi, Pi or the Golden Mean were in elementary school? I didn't. They see them now everywhere they look, point it out and get rewarded.
