respondents were expected to decompose the product of 75m × 5 into kilometres and metres. As shown in Table 4.6, respondents committed an error called by leaving 375cm in the column of centimetres. Remediation decomposition of units of these errors on converting units of time and length can be done by familiarizing students with relationships of hour and minutes”, metre and centmetres”, and “an “a kilometer and metres”. This familiarization should be followed by extensive “a exercises on changing one unit into another. 4.4.2 Estimating Length/Height, Weight and Time It is very useful to be able to estimate length, mass or weight, volume and time, because it may always not be easy to measure them. Estimation of these quantities is taught in Standard IV, and VI. In items 43, 44 and 45, respondents were requested to estimate the length of a classroom door in centimeters, the time it takes to walk from the classroom to the head teacher’s office, and to estimate the weight of a newly born baby. Knowledge and Competences/Skills tested Estimating heights and lengths Estimating the time on an activity Estimating the weight of a substance Sample questions Item 44: Estimate the length of your classroom door in centimeters Item 45: How much time will you take to walk from your classroom to the head teacher’s office? Item: 43: Estimate the weight of a born baby
