An incredibly versatile teaching tool. You can change the start number and change the step size, then try and find the hidden number. Choose from several difficulty levels. Ask the children to discuss the different methods they could use to find the missing number.
Can be used to explore sequences (including negative numbers and decimals), multiplication tables, as well as reasoning about numbers.
Recognise and continue the sequences involving fractions, shapes and colours. Lots of control over level including unit fractions and improper fractions. Extend children by choosing harder levels which require extending the sequence by finding general rules.
Use a Venn diagram to sort a variety of 3D shapes according to their properties, including: whether they are pyramids or prisms, the number of faces, edges and vertices and whether they have a curved surface.
Sort a variety of 2d shapes on a Carroll diagram. Sort by one or two conditions. Sort triangles - scalene, equilateral and isosceles. Sort quadrilaterals, pentagons, hexagons, heptagons and octagons, as well as parallelograms, rhombus, kites and trapeziums. Also sort according to a shapes properties such as acute, obtuse, reflex or right angles and symmetry or whether it is a regular shape.
Updated December 2017 - this is a new version that will work on a tablet or computer.

View full screen in your browser. This ITP generates a 100 square. Choose a colour or the grey mask. You can then click on individual cells to hide or highlight them in different colours, and by clicking on the box at the left-hand foot of the grid and using the pointers you can hide or highlight rows and columns. The prime numbers and multiples can also be highlighted. You can change the number of columns from 3 up to 13, the starting number, and its position – either top left corner or bottom left corner of the grid. Choose the mask option to create a temple that can be moved around the grid to hide or highlight particular groups of cells. The template can be rotated using the single arrow button. The ITP can be used to explore different multiples, number sequences and patterns on grids of different sizes. The superimposed masked template can provide practice at adding groups of numbers and enable children to hypotheses about the sums and difference of the numbers. The ITP can develop children’s ability to predict and generalise. Changing the number of columns provides a new grid to test general statements about the relationships between numbers and to look for counter examples.
