Interactive protractor6/2/2023 ![]() You can set the scale on the cylinder to a maximum of 50, 100, 200, 500 or 1000 units and the scale interval to 1, 2, 5 or 10 units. This ITP allows you to control two taps that pour a liquid in and out of a measuring cylinder. Selecting different scales on the number line and hiding and revealing the numbered intervals can support children’s estimation skills and ability to read horizontal scales. The ITP can be used to model calculation strategies for addition and subtraction and to develop children’s understanding of the sums and differences between positive and negative numbers. The maximum and minimum values on the number lines can be altered and the numbered intervals can be hidden and revealed. You can hide and reveal the numbers in the boxes, which will also hide and reveal the respective numbers in the calculation. Depending on the order of the two markers you can show the sum and difference between the two numbers and the calculation represented. Two markers with numbered boxes can be moved along the number line. The ITP can also be used to demonstrate the effect of repeated multiplication and division by 10.įor more multiplication and division resources click here. The ITP can be used to explore, and to encourage children to predict the effect of multiplying and dividing by 10 and 100. The cards in the second row do not move in order to highlight the shift in the digits when multiplying or dividing. The cards will not move if the result is greater than 99 999 or less than 0.01. The cards in the first row move when the multiply or divide buttons are selected. These decimal numbers can be placed in either of the two middle rows. By dragging cards from the set of digit cards, different decimal numbers can be displayed. This ITP allows you to demonstrate the effect of multiplying and dividing by 10 and 100. You can use the ITP to demonstrate and explore properties of shapes, such as the internal angles of different pentagons and the properties of opposite sides of various parallelograms in different orientations.įor more shape and space resources click here. For reflex interior angles the value of the exterior angle is shown. The angles created at vertices can be measured using the protractor and their values can be displayed or hidden. Lengths of sides can be measured using a ruler. Once a shape has been created, its vertices can be dragged to new positions to create new shapes. ![]() To close a shape select a vertex at any point and drag it onto the required point to create a closed shape. ![]() As each vertex is created it is labelled and joined to the previous one. The grid size can be changed, and the grids hidden and revealed. This ITP allows you to create a number of connected vertices on a grid. They will remain freely available to all without the need for a subscription. I am remaking the ITPs so that they will work on all modern browsers and tablets. Changing the number of columns provides a new grid to test general statements about the relationships between numbers and to look for counter examples.įor more addition and subtraction resources click here. The ITP can develop children’s ability to predict and generalise. 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 be used to explore different multiples, number sequences and patterns on grids of different sizes. The template can be rotated using the single arrow button. Choose the mask option to create a temple that can be moved around the grid to hide or highlight particular groups of cells. 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. The prime numbers and multiples can also be highlighted. 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. This ITP has been remade so that it will work in modern browsers.
