Strategic thinking and flexible calculation are needed for the addictive iPad app Logic Squares. The 25 levels, which increase in complexity, help children to learn number concepts and apply calculation skills.
As the challenge increases, children's understanding of key mathematical ideas will deepen. Players become familiar with different operations and number signs, and there are different ways to complete each grid. You can use these part-completed levels to discuss the tactics needed to complete each puzzle.
To complete a level, numbers from underneath are positioned on the grid until each line is correct. Players need to use the numbers wisely so they don't run out of the numbers that they need for the final calculation!
When the player clicks 'check' any mistakes are highlighted in red so corrections can be made.
Levels 16-25 use larger grids and become increasingly complex. Numbers have to be positioned strategically, with careful thought given to the order that lines are completed.
