Maths Cala Plane Shapes

This document provides guidance for learners completing a Calculated Academic Learning Activity (CALA) on calculating the number of tiles needed to cover a classroom floor. The CALA involves measuring the classroom, calculating its area, collecting tile size data, calculating the area of one tile, and determining the number of tiles needed. Learners will be assessed on their measuring tools and technique, use of measurement units, and accuracy. The facilitator guidance outlines how to assess measurements, calculations, and award marks.
