Use coordinates in the first quadrant to draw, locate and complete shapes that meet given properties
Coordinates - reasoning about position and shapes
Find the missing coordinates on a given shape, reflected in a mirror line, or the midpoints of straight lines. Choose to find coordinates in the first quadrant, or all four quadrants. Provides lots of opportunity to reason about shape and position.
I am remaking the ITPs so that they will work on all modern browsers and tablets. They will remain freely available to all without the need for a subscription.
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.
You can explore the use of the different quadrants by hiding and revealing the grid to support children’s understanding of the coordinate system.
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.
