This Term in 5/6 Perry, as part of our place value unit in mathematics, we undertook a series of lessons on estimating. We learnt that good estimating skills allows us to use simpler numbers (estimates) to determine the reasonableness of an answer when solving mathematical problems. Students took part in an exercise where they measured how far they could throw a bean bag, roll a hula hoop, do a standing jump and also measure how far they could run in 5 seconds. After each turn students measured accurately the distance and then converted the figure to an estimation. These rounded estimates were then much easier to use in further calculations than the exact measurements.
