Question: Can you connect 9 dots laid out 3x3 using 4 straight lines, without lifting your pencil from the paper? Suggested Materials: paper
pencil
4 sticks of uncooked spaghetti and 9 pennies or 4 toothpicks and 9 Cheerios or other flat breakfast cereal
or whatever other manipulative is handy to simulate the lines and dots Procedure: - Place 9 "dots" on your desk or table.
- Using the 4 sticks experiment with connecting the dots using 4 straight lines. (Or just use pencil and paper.)
Questions to ask yourself as you work: - Can you do the puzzle if the lines do not cross each other?
- Must your lines stay within the grid of dots?
- What if you extend a line past the edges of the arrangement of dots?
