# Describe positions on a 2-D grid as coordinates in the first quadrant

New Maths Curriculum (2014): Year 4 objectives.

 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. For more shape and space resources click here. ITP Coordinates New January 2013: I have created a new game which involves finding 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. View full screen in your browser.  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. This resource is freely available to download from the archived Primary Framework site.
