조안호 소장님이 짚어주는 흔들리지 않는 초등 연산의 핵심!(#구구단 만큼 중요합니다.)

💡 Many parents assume that if their child gets all 100 questions right, they know everything and immediately move on to calculations involving larger numbers. However, if calculations involving two-digit and one-digit numbers do not come to mind in a second like multiplication tables, that skill is nothing more than a sandcastle. In today's video, we will correct the flawed arithmetic learning methods that rob children of the initiative in math. ❌ Do not obsess over three-digit addition. It rarely appears in middle and high school math. ❌ All calculations are ultimately a repetition of the basics. The true nature of multiplication and division is, in fact, the addition and subtraction of "two-digit + one-digit" numbers, similar to multiplication tables. ❌ The trap of vertical calculation. A child who unconsciously attempts to write out even simple calculations like 15+7 using vertical calculation lacks mental arithmetic ability. This basic arithmetic, learned at the end of first grade, ultimately holds them back in high school math. You must build a foundation so perfectly that the answer comes out even if you wake them up from sleep; only then will mental arithmetic become possible at higher levels. Parents' accurate judgment determines a child's mathematical foundation.
