One-to-one correspondence is an early learning math skill that involves the act of counting each object in a set once, and only once with one touch per object. Rote counting and counting with one-to-one are very different.Rote counting is just reciting the numeral names in order, “One, two, three, four, five…” But counting with one-to-one involves actually touching each object and saying the numeral name aloud, which is a much more complex skill for young children.Activities that involve real objects that children can hold in their hands and manipulate are going to be the most effective for teaching the concept of one-to-one correspondence. One of these activities involved counting with unicorn “horns”. Using pipe cleaners as the “horn”, students slid beads while counting.Each “horn” had a number ranging from one to ten. They were directed to slide the number of beads that matched their number. It was so exciting to see how sparkly our “horns” became!
