Common Core is rubbish.
Set the kid up to fail. NICE
As a math teacher has explained to me, Common Core Standards still do not teach students how to make change from paper money.
Children just are not ready for such complications in the early grades. They are sponges ready to memorize facts to use as they become adept at reasoning.
Common core is rape of the child’s brain, mind and psycholology.
Read Dorothy Sayers lost tools of learning. Although old and the musings of one not steeped in modern educational techniques, she has a lot to say to those who have forgotten the past:
“My views about child psychology are, I admit, neither orthodox nor enlightened. Looking back upon myself (since I am the child I know best and the only child I can pretend to know from inside) I recognize three states of development. These, in a rough-and- ready fashion, I will call the Poll-Parrot, the Pert, and the Poetic—the latter coinciding, approximately, with the onset of puberty. The Poll-Parrot stage is the one in which learning by heart is easy and, on the whole, pleasurable; whereas reasoning is difficult and, on the whole, little relished. At this age, one readily memorizes the shapes and appearances of things; one likes to recite the number-plates of cars; one rejoices in the chanting of rhymes and the rumble and thunder of unintelligible polysyllables; one enjoys the mere accumulation of things. The Pert age, which follows upon this (and, naturally, overlaps it to some extent), is characterized by contradicting, answering back, liking to “catch people out” (especially one’s elders); and by the propounding of conundrums. Its nuisance-value is extremely high. It usually sets in about the Fourth Form. The Poetic age is popularly known as the “difficult” age. It is self-centered; it yearns to express itself; it rather specializes in being misunderstood; it is restless and tries to achieve independence; and, with good luck and good guidance, it should show the beginnings of creativeness; a reaching out towards a synthesis of what it already knows, and a deliberate eagerness to know and do some one thing in preference to all others. Now it seems to me that the layout of the Trivium adapts itself with a singular appropriateness to these three ages: Grammar to the Poll-Parrot, Dialectic to the Pert, and Rhetoric to the Poetic age.”
