Thinking Mathematically: Same-Sum Puzzles

What is Mathematics?

While there is no simple definition of mathematics, it is clear that young children and mathematicians have very different ideas about what math is. For young students whose experience with math is often limited to learning "math facts" and practicing algorithms, it is easy to think that mathematics is nothing more than routine arithmetic. It becomes evident only much later that mathematics is not really about numbers at all, but about reasoning.

The problem sets and activities available here are meant to supplement the regular curriculum for students in the early grades (approximately K to 3). They are meant to emphasize mathematical reasoning and problem solving over content knowledge.
