Students get to practice their problem-solving skills on this worksheet titled "Draw Lines to Cover Every Number in a Grid: A Fun Brainteaser Activity." All the puzzles feature a grid. Some feature numbers where students have to follow the numbers, drawing a certain number of lines with their pencil without starting or stopping on a blank spot. Lines can only go left, right, up, or down, but it's okay for lines to cross. Worksheets start with an example so students can see how it's done.

Additional puzzles get more difficult because they feature dots instead of numbers. Students start on the square and draw a certain number of lines to connect all the dots. Without ordered numbers to guide them, students really have to use their critical thinking skills.

Brain teasers and puzzles are a fun way for students to practice their problem-solving and critical thinking skills, which are useful in math, science, and reading. It can be helpful to provide students with a step-by-step puzzle that starts easy and gets harder as they get practice. For example, before asking students to draw a certain number of lines between dots on a grid, they can do a similar problem with numbers first. They can get used to following the order of the numbers before figuring out which way to draw the lines when there are no numerical directions to follow.
