Guess What...?
Colmer, Ben

Teachers often encounter difficulty in teaching estimation of measurement to young children. The intention when teaching the typical "jelly bean jar" classroom activity is to help children develop estimation skills, but most children cannot conceptualise the difference between guessing and estimating. The fact is that many students view estimation as a difficult technique where their success is measured by how close their own estimation is to the teacher's estimation; a misconception that is far removed from the useful and practical experience estimating should be (Muir, 2005). The NSW Board of Studies (2002) emphasises the importance of children's participation in estimation activities through extensive practice. Teachers need to provide students with opportunities to improve their number, spatial, and measurement sense through experiential estimation. Hence, the intention of this article is to illustrate that estimation is a skill that is practical and relevant to student's lives, and to provide teachers with some purposeful strategies to help develop their students' skills in estimation.
