Task administration: 

This task is completed with pencil and paper, and other equipment.

Equipment

Multi-link cubes; balance scales; a new large roll of sellotape; a full packet of staples (5000 rapid E6/6 staples); a set of ten gram weights.

  • For the estimation part of this task give each student ten multi-link cubes, and a chance to feel the weight of the sellotape and the staples.
  • For the measurement part, let each student use a set of balance scales, rods of ten multi-link cubes joined together, individual multi-link cubes and 10 g weights.
  • Some students may need to be prompted to count in tens when using the 10 g weights.
