This card sort is designed as a cooperative activity which can be used to develop mathematical vocabulary or as a plenary on the subject.
This resource contains seven cards, with names, images and descriptions for children to match (right angle, acute angle, obtuse angle, parallel lines, perpendicular lines, horizontal line, vertical line). These could be given out as a complete sheet for children to cut up, sort and stick into books or pre-cut, laminated and sorted into envelopes for children to be able to sort and re-use them.
- identify right angles
- identify whether angles are greater than or less than a right angle
- identify horizontal and vertical lines and pairs of perpendicular and parallel lines.
