This puzzle resource is a very difficult challenge and brings up to date this earlier resource (not tablet compatible) so that the same challenge can be worked with on all devices. It is simple enough to understand. Swap tiles so that each number in the triangle is the absolute difference between the two numbers below. The absolute difference is effectively the same as subtracting the smaller number from the larger number, whatever order they appear in.
The bottom numbers will always appear as correct as there are no numbers below to produce them. Note that the resource tells you when the absolute difference is correct but NOT that the tile is in the correct place to solve the puzzle.

This math practice game is for children to employ quick addition and subtraction skills. It is compatible with all devices with a modern browser.
The player controls a craft using thrust to go up and left and right controls. Going down is left to gravity. The player is told to take the craft either higher or lower than their last platform by a certain number. The player must then get their craft to the correct platform before the timer runs out and an astronaut teleports to their doom on that platform. If the player gets to the platform with time to spare they can instruct the teleport to happen immediately by pressing space bar on computers or the big green onscreen button on tablet devices.
Power ups come in the form of speed ups and icons that tell you what the tens or units are of the correct platform. Extra hazards come in the form of fireballs which will push your craft down.
On touch devices the game will attempt to detect this and will display an on screen set of controls. On computers the cursor keys are used for direction and thrust. Space bar will teleport the space man in immediately.
Play math game on line with no advertisments.
You can also get this game as an advertisment supported app on the iPad.
Use this challenging iPad, Android or IWB resource to teach and practise mathematical reasoning based on column addition skills.
All of the numbers to make a complete addition are given by the resource. The player needs to switch the tiles around to make it correct. The tiles in the question and answer parts can, and will need to be, interchanged. The numbers and positions are totally random meaning that sometimes the resource will offer a greater challenge than at other times. While the answer is incorrect the cross will remain on screen, when it is correct a tick will replace it. A score is given so that teachers can utilise the resource as a worksheet requiring to see, for example, a score of 5.

After teaching children how to use a number square to develop basic addition skills using this number square resource, this resource is ideal for providing an opportunity to practise. It has the same look and feel, but whereas the other resource is designed for demonstration this one sets questions.
After tapping Begin the 1 minute timer starts and an addition question appears at the right of the screen. The first number is illuminated in the grid and children use their skills to tap the square that holds the answer.
The resource is compatible with all modern devices, both tablet and desktop, and so should be usable in most classroom situations as well as being recommended for children to continue using it at home to consolidate their skills. Parents pointed to the previous resource can also help to teach the skill using a resource familiar to their child from school.

Many hundred squares (my own included) offer lots of options for using them for different things. Most of the time they are used for a specific purpose such as teaching addition and all of the options needlessly clutter up the screen. This iPad, Android and IWB compatible teaching resource is specifically for teaching addition. It therefore is less cluttered and has features designed to aid this task. Select a start number by touching the board and then show adding tens and units by touching the T and U squares. The calculation can be shown in horizontal or column format.

A supporting resource for children to practise the skills taught with this resource is Addition Square Challenge.
This teaching resource for iPad, Android, and IWB is for visualising addition for younger learners. Generate a new addition (maximum sum of 20) cover one of the numbers and use the counters to represent the numbers being added. The counters can be picked up and placed in the containers to assist in this explanation.
In it self this resource will provide no tuition as it is designed to be a tool to assist a teacher or adult explain to children, either on an IWB for a whole class or on a tablet with a small group or an individual.

This teaching resource, compatible with iPad and Android tablets, provides a chance to practise completing additions where one of the numbers to add is missing. Drag the tiles on the right to fill in the blank space. A correct answer results in the addition disappearing. An incorrect answer leaves the addition there but also adds another to the top. Children can be challenged to get the best time.
The resources does not end the game when the lines reach the top and this is intentional allowing teachers and children to ignore the challenge element of they want to and just practise or demonstrate using the resource.
The timer starts the moment the first tile is released and can be reset using the reset button at anytime.
