My group was learning estimation of parts of a cob of sweetcorn. Norah and Stephanie were in my group. The closest estimation we had was for the row of kernels. We estimated 13 but the actual amount was 18. The rest of the estimations were wild guesses. The skill we had to use was rounding off. I found this a little hard to work with because no one in my group had a netbook at the time. Next, I would like to revise algebraic expressions.
