Fourth - Shape, position and movement

Standard 4.GMD.1.2 - Practice graphing images after a scale factor dilation using coordinate graphs.

Included Skills:

Angle, symmetry and transformation
• Having investigated the relationship between a radius and a tangent and explored the size of the angle in a semi-circle, I can use the facts I have established to solve related problems.
• I can apply my understanding of the properties of similar figures to solve problems involving length and area.
• I can plot and describe the position of a point on a 4-quadrant coordinate grid.
• I can apply my understanding of the 4-quadrant coordinate system to move, and describe the transformation of, a point or shape on a grid.
• Having investigated patterns in the environment, I can use appropriate mathematical vocabulary to discuss the rotational properties of shapes, pictures and patterns and can apply my understanding when completing or creating designs.
• Describes rotational properties of shapes, pictures and patterns, including the order of rotation.
• Uses knowledge of rotational symmetry to complete designs.
• Uses a four-quadrant Cartesian grid to read and plot coordinates.
• Applies understanding of translation to reflect or translate an object on a four-quadrant grid.
• Uses similarity to find unknown lengths of 2D shapes.
• Applies knowledge of the relationship between the tangent and radius to calculate sizes of missing angles.
• Applies knowledge of triangles, angles and circles, including semi-circles, to solve problems.
• Identifies transformation by reflection or translation of a point or shape on a grid.
