The double dice button also reorders the multipliers around the inside edge of the dial and all the numbers are hidden. The ITP can be used to practise multiplying by one- and two-digit numbers and decimals.
Hiding different sets of numbers on the dial promotes reasoning and explanation. The ITP can also be used to practise the recall of division facts and use of these number facts to generate other facts. Setting the numbers on the dial in a context also provides opportunity for problem solving. Using the pointers on the numbered button, you can create one, two or three spinners at a time. The pointers on the shape button allow you to select the number of sides. Once this has been determined, click on the shape in the button to display the spinners.
By clicking on the centre point of a spinner the spinner will spin to generate a random number identified by the arrow. The numbers on the spinners can be changed. They toggle when you click on them. The ITP can be used to generate data quickly and help children to understand the behaviour of random numbers.
Using two spinners you can look at the distribution of the sums and differences between the numbers generated and introduce situations where children are asked to predict outcomes, which they can then test with the data generated by the ITP. This ITP displays up to 20 coloured counters and the corresponding addition sentence. The number of counters you select, appear on the screen in purple. Click on any counter to change its colour, the number sentence also changes.
To hide and reveal the number sentence, click on the box with the question marks. You can replace a number in the number sentence with a question mark by clicking on the number, and drag counters around the screen to form groups.
Addition can be changed to subtraction by clicking on the addition sign in the box. Counters can be dragged into the displayed box, which you can make opaque to hide the counters. The ITP can be used to model addition by combining and counting, and subtraction by partitioning and taking away.
The hide and reveal options allow you to pose questions with unknown numbers in different positions in the number sentence. Partitioning counters in different ways helps children to identify all sums and differences of numbers to This ITP sets up an empty grid into which you can place counters. Counters can be added singly, working from the first empty top left-hand corner cell, or in bulk clicking on a cell in the final row. As each column is completed it is numbered. The division calculation representing the number of highlighted counters divided by the number of rows can be revealed and hidden using the equals sign button.
The answer appears when the equals sign in the calculation is clicked. Any remainder can also be shown as a fraction. In the example, below, there are 17 counters in a grid with 5 rows. Three columns are completed and there are 2 counters in the incomplete column. Keeping the number of counters fixed but changing the number of rows demonstrates the effect of changing the divisor in the calculation.
Children can explore the effect different divisors has on the remainder and they can look for division calculations whose remainders satisfy particular properties. This ITP allows you to display up to 30 counters or shapes on the screen.
You then select a number to be the divisor in a division calculation. A number line displays the number to be divided. As individual counters or shapes are clicked and dragged to form a group the size of the divisor, they change colour. In this example 22 counters were chosen and the divisor set to 5. In the example shown below, 3 sets of 5 shapes have been selected and moved to the number line, which shows each group as a jump. Four more counters have been dragged together and the fifth is about to be selected.
The answer to the division calculation is shown at the bottom of the screen. The ITP can be used to model division as grouping and to link this process to jumps on a number line.
It can also introduce children to how remainders are recorded in the answer. This ITP allows you to use a marker to identify the coordinates of points on different grids. You can mark points and draw lines and shapes.
You have a choice of 1, 2 or 4 quadrants to work in to introduce both positive and negative coordinates. The ITP can also be used to explore the properties of 2-D shapes and to predict translations, rotations and reflections of various shapes in the different quadrants. Interactive whiteboard tools can be used to draw mirror lines or points of rotation.
The mirror can be set to a horizontal, vertical or diagonal orientation and then adjusted by dragging it around a central point. Squares on the grid can be highlighted in yellow and the shape created can be moved to a new position on the grid. The reflection of these highlighted squares can be shown in blue, or hidden, with the mirror fixed or while the mirror is being rotated. You can use the ITP to help children to predict the position of shape that is to be reflected and to look at what happens to an image as the original shape is altered or its position is changed.
This ITP allows you to add different masses to or from a scale pan. You can add masses of 1, 2, 5, 10, 50, and units. The pointer or hand shows the total mass. The maximum value of the circular scale can be changed together with the size of the interval. A digital readout can also be hidden or displayed. A red marker can be used to keep a track of previous values and to set target quantities. Using different scales can support their estimation skills in reading circular scales and solve problems set in the context of mass.
This ITP displays a thermometer. The scale, range and the interval markers can be changed and a slider control can be dragged up and down the length of the thermometer to set the height of the column.
A second marker indicates the last reading so that comparisons can be made. This marker can be fixed in position if required. The positive or absolute difference between two values can be displayed, and the change in the temperature as the marker is moved. The slider controls can be used to introduce and model strategies for addition and subtraction that involve positive and negative numbers. The language of number can be developed, giving meaning to calculations such as subtract negative 3 from negative 7.
This ITP displays on-screen analogue and digital clocks separately or together. The clocks can be moved around the screen and their sizes altered. Times can be adjusted in different intervals of time.
The clocks can run in real time or from a set time and over any interval. The clock can be stopped and started. The ITP can be used to support the teaching of the telling of time, to identify time before and after given intervals and to undertake calculations that involve time.
This resource is freely available to download from the archived Primary Framework site. This ITP displays an on-screen ruler you can use to measure lines and the sides of shapes.
There is a choice of rulers and five screens to use to demonstrate measuring length. You can draw your own lines and shapes or select those that are available on the ITP. The ITP can be used to demonstrate how to use measure using different rulers. You can develop their ability to estimate length against a given scale and use the ruler to check the accuracy and demonstrate what to the nearest half and whole unit means. It generates a number line.
Clicking on the hidden buttons below the number line creates an interval displayed as a hidden number line. A marker can be placed at different points on a number line. This ITP allows you to set up a multiplication grid to demonstrate the grid method of multiplication for whole and decimal numbers.
The grid size can be changed to accommodate different calculations. The calculation is defined at the bottom of the screen by changing the digits using the hidden pointers. Decimal points can be inserted by clicking between two adjacent digits.
The numbers are partitioned and the respective components in the calculation revealed and hidden by clicking on the?
These values appear in the addition calculation and the answer confirmed clicking on the equals sign below the plus sign. The numbers around the grid, and in the calculation, can be hidden and revealed. To do this, hover over and clicking on the rectangular strips, at the right hand side of, or below, each number.
This ITP displays regular polygons with 3 to 10 sides. A background grid can be revealed and hidden and the displayed polygon can be enlarged using the pointers on the polygon button. The polygon can be translated and rotated. A vertex on the polygon can be dragged to another position to change its shape and properties.
Double clicking on a vertex allows you to add remove the vertex or to add an extra vertex at the mid point of an adjacent side. You can use the ruler or protractor to measure dragging it and using the circular button to rotate it to the required position. The ITP can be used to explore the properties of regular and irregular polygons. This ITP allows you to colour in cells on a grid, a full cell or half a cell, or to place a circular counter into a cell.
There are three choices of grid size: 5 by 5, 10 by 10 or 20 by The grid can be hidden or replaced by a pin board around the points of which rubber bands can be stretched.
The making of different shapes and patterns can support the teaching of number, shape and space and problem solving, for example, to identify the positions of counters in a given sequence or to find the number of nets of an open cube.
The flexibility offered by the ITP allows it to be used to support a variety of teaching and learning contexts in mathematics. This ITP allows you colour the equilateral triangles set out on an isometric grid. The grid can be hidden or become an isometric pin board. One of three different rhombuses can be selected and dragged to different positions on the grid.
These three rhombuses can be locked together to form the isometric view of a cube. Skeleton outlines of rows and columns of cubes can be formed this way and by colouring in two adjacent triangles, coloured faces can be created. The ITP can be used to explore properties of shapes and space.
The making of different shapes and patterns can support the teaching of number and problem solving, for example, to explore the interior and exterior angle and symmetry of polygons made up of equilateral triangles and to identify the patterns in triangle numbers. It can be used in conjunction with the Area ITP to look at the nets of 3-D shapes represented on the isometric grid.
This ITP create stacks of numbered cards and individual cards. Cards appear face down. Cards can be sequenced or generated as a random set, to include whole numbers, decimals or fractions. The ITP can be used to display sets of different numbers that children can compare and order.
The stacks created can support work on identifying, describing, extending and generating sequences. Different stacks can be used to display and reorganise particular numbers from which children can hypothesise and go on to explore properties and patterns in numbers. This ITP shows how a number line can be developed from a row of 10, 20 or counters.
It behaves like a short film. The film is in four stages. You can pause at the end of each stage. The ITP can be used to help children to understand how a number line relates to discrete objects placed in a row, and to support their counting and recording skills.
Using the different sequences the number line image can be developed to increase the interval between numbers and to support addition and subtraction activities, moving from the counters to the number line.
