3 = 2 + 1

A numerical relationship or statement most kindergarteners and younger elementary school students would reject as being an equation, because in their minds the “answer” or the “sum” must always be on the right side of an equation.

When grades 1–3 students don’t consider numerical liaisons like 3 = 2 + 1 and 1 = 3 – 2 as valid equations or mathematical sentences, their responses reveal a fair bit about their thinking processes.

1 + 2 + 3 = 1 × 2 × 3 

The nontrivial solution to the equation a + b + c = a × b × c, where a, b, and c are positive integers—the sum and the product of three whole numbers are the same.

Besides 1 + 2 + 3 = 1 × 2 × 3, the numbers 1, 2, and 3 form the set of three integers such that each divides the sum of the other two, and their reciprocals show that the number 1 can be expressed as the sum of three unit fractions: 1 = 1/2 + 1/3 + 1/6.

1 + 2 = 3 

The solution to the equation a + b = c, where a, b, and c are consecutive integers; or where b = a + 1 and c = a + 2.

If 1 + 2 = 3 and 4 + 5 + 6 = 7 + 8 are the first two terms of a sequence of equations, what is the sum of the third equation in the pattern?

3 + 2 = 1 

A mathematical statement most grades K–2 students would disqualify as being an equation, thus revealing their partial understanding of the meaning of an equals sign, which has different meanings.

What percentage of elementary math students (and their teachers and parents) would claim that statements like 1 + 3 = 2, 3 + 2 = 1, and 2 × 3 = 1 aren’t equations, because the sum or product is incorrect?
