Measure words are important in Chinese, I recommend that kids start learning measure words when they learn numbers.
I made this set of measure words cards for my 1-year-old son, I will teach him numbers, counting, and measure words, additionally, he will learn the names of these objects on the cards.
I printed these cards, cut them, and laminated them with A6 lamination paper.
