These Brain Teaser Puzzles require students to position a set of designated numbers onto an arrangement of squares, so that all lines of numbers add up to the same sum. This requires a lot of mathematical reasoning skills, and perseverance to find the solution through trial-and-error. The puzzles increase in difficulty with each one, beginning with two addends and a sum of three, and eventually working up to four addends with a sum of eighteen. The lower-numbered puzzles are developmentally appropriate for most first-graders, however advanced first-graders are able to solve the higher-level puzzles through repeated trial and error. Likewise, even fourth- and fifth-grade students will be able to work on and solve these same puzzles at different paces depending on their level of critical thinking and mathematical reasoning skills.
