Featured Link: Do You SuDoku?

The Sudoku Puzzles have become very popular with adults. &nbsp The challenge is to place each of the digits 1-4 or 1-6 or 1-9 in each box within the larger puzzle box so that no digit appears twice in any row or column. &nbsp The puzzles require logic to reason through the placement of specific digits and the ability to scan the entire puzzle for starting clues. &nbsp Now teachers can also use this popular format with students, thanks to this SuDoku for Kids website.

• Daily SuDoku for Kids presents easier versions of the SuDoku puzzles especially designed for younger students. &nbsp Each SuDoku is rated as easy, medium or hard so that teachers can select the most appropriate versions for their students. &nbsp An archive of past SuDoku problems and answers are available and are easily printed for use with students. &nbsp Consider introducing this problem-solving activity as an enrichment or center activity for interested students. &nbsp Solving the problems requires logic, methodical approach and persistence.
• Download the &nbsp &nbsp SuDoku Templates (both 4x4 and 6x6 grids) to use as a reusable overhead or place the templates in sheet protectors so that students can use dry erase markers to solve the posted SuDoku problems and then reuse the templates for future problems. &nbsp Both 4x4 and 6x6 SuDoku problem grids are included so that teachers are able to differentiate problems for students in their classes.
