Shikaku, or in Japanese Shikaku Ni Kire, is also called Rectangles, Divide by Squares or Divide by Box. The goal of this number puzzle is to divide the grid into rectangular and squared blocks with numbers that represent the areas of those shapes.

You can find a very good and complete explanation on Wikipedia!

The rules are simple and our printable math number puzzles are highly addictive. Many maths teachers use them when they teaching about area and perimeter, or even about tessellation. Shikaku puzzles are excellent logic skill builders for kids and math learners. The Shikaku number logic puzzle raises spatial awareness and enhances logic, problem solving and reasoning skills. Have a look at the following Shikaku maths puzzle for kids (5 by 5 grids are easier) and its answer:
The objective of the game is, as said, to fill the grid with squares and rectangles. In the above example the 'six' and the 'four' are the big give always. The 'six' can only be a '3 by 2' rectangle and the 'four' only a '2 by 2' square. Once we filled these in, this puzzle can be solved in a matter of seconds! Please note that the Shikaku number puzzle is all about trial and error and the ability to try new ideas. Don't give up when stuck, just try again. We like the idea that when a puzzle is completed our math students can colour the rectangles.
