Another IWB, iPad or Android resource to challenge children’s (or anybody’s) thinking skills. Choose your start point from any of the circular nodes on the grid. You must then visit each straight section in only 19 moves. They will fade out to show they have been visited. As there are 17 straight pieces and the minimum you can complete this puzzle in is 19 you will obviously have to revisit a couple of straight sections.
You can only move along the grid lines one circle at a time and each of these counts as one move.

Another counter sorting puzzle for iPad, Android and IWB along the lines of the Two At a Time puzzle. This is very similar as you must arrange the pattern of shapes so that there are 4 octagons followed by 4 stars with the 2 blanks on the far right. The twist with this puzzle is that every time you move the two shapes they flip relative positions. This makes it a bit harder to visualise your strategy and offers a simple to understand, but challenging to solve, puzzle.
The top blue bar lets you select which two shapes to move the lower blue bar will move the selected two shapes. You must always move two shapes.
With a modern browser this resource will run on tablets, phones, and computers.

A magic square maths variation on the sliding puzzle used in the Letter Blocks resource. Use this on an IWB, computer, iPad or Android device to take up the challenge of making each row, column and the two diagonal lines add up to 12. The catch is that one of the numbers cannot move and must be locked before the tiles can start to be moved. After this the puzzle works like any other slide puzzle where you must try to meet the finishing condition by sliding the tiles into position. The blank counts as zero for working out the sums. The puzzle can be solved in just 19 moves but a good way to solve it is to try to work out the correct finish position first and, from that, which tile never moves.
Tapping a tile will cause it to move into the blank if its a valid horizontal or vertical move.

A modern browser is needed on PCs. IE10 or higher.
A mathematical based puzzle for IWB, iPad and Android that requires some careful numeracy thinking and some informed trial and error. When the resource opens you will see that both multiplication calculations give the same result of 3634. The highest number that can be the answer for both calculations using each of the nine digits once is 5568. The challenge is to arrange the numbers until both calculations equal 5568. The resource will take care of the calculating but the player will have to think hard about the results of multiplication to make progress. Random moving of tiles is likely to take a long time!
Tap one tile and then another to swap them.
The resource requires a modern browser and will work on all platforms.

Another IWB, iPad and Android compatible teaching and learning resource for problem and puzzle solving. Encourage children to think about how to efficiently approach problems and not to give up by setting them this simple to understand puzzle. The goal is to reverse the order of the counters so that there are 3 purples, then 3 blues and finally the blank space. Counters can move to an adjacent empty place or hop over one or two other counters to get to it. The resource will only allow correct moves. It can be done in 10 moves. Tapping any counter will move it to the blank space. Tapping reset will set it all back to the beginning. First try to solve it in any number of moves and then try to distill this down into the most efficient process.
Compatible with modern browsers on all devices.

This teaching resource, compatible with iPad, Android and IWB is another puzzle for encouraging children to work on their problem solving skills. It is a variation on the traditional 15 Puzzle. Slide the tiles around until they run in alphabetical order from the top left.. Solving it in any number of moves is one challenge but aiming for perfection and completing it in the minimum possible 23 moves should prove even more so.
The resource should run on any modern browser on any device and so could make a useful homework challenge that most children will be able to access on whatever they have at home.

A similar resource, but requiring some mathematical reasoning is here.
This iPad, Android,and IWB teaching resource is another puzzle for encouraging children not to give up on problems and to develop problem solving skills. To solve the puzzle all of the stars must be grouped together and so must the pentagons. The two empty spaces can be left at either end of the row. Each move must be of two shapes together and they cannot be switched in their relative positions. This resource won’t allow any of the puzzle’s rules to be broken but as it is a puzzle that is easy to replicate with counters it is important to be aware of the rules.
The top blue button is for moving to select the two shapes you want to move. The bottom blue button will move the two selected shapes. If you attempt a move that is not allowed it will all jump back to the previous position. The puzzle can be solved in just 5 moves. Try to solve it first and then try to pare down the number of moves.
