3 Class 6 Math Teacher Reprt Fractins and Angles September 07 C-R-O Chart This sectin categrises questins as Critical, Recmmended and Optinal. These are pririty levels assigned t questins that need t be revisited t explain the cncepts behind them QUESTIONS QUESTIONS 0 QUESTIONS Discussin Pririty Cunt Q.N. Critical 07, 4, 7, 0, 9, 0, Must revisit withut exceptin Recmmended 08 5, 6, 9,,, 5, 6, 8 Imprtant t revisit, but lwer pririty than Critical Optinal 0 All ther questins Optinal t revisit Questin numbers are as per versin Remediatin Supprt Out f the critical and the recmmended questins identified abve, here are sme remediatin ideas develped by EI's subject specialists. Questin numbers are based n paper versin. What fractin f the fish in the aquarium are mving twards the weeds? Half Quarter 4 Three Quarters One Third Critical Crrect Answer: Optin Optin Optin Optin 4 9% % % 47% Distractr Explanatin: Students are expected t see that nly ne pair f fish ut f 4 pairs are swimming twards the weeds. Students answering ptin 4, dn't understand that a fractin represents a 'part' f the 'whle'. They seem t think that the number f fish swimming twards the weeds crrespnds t the numeratr and that swimming ppsite (6 f them) crrespnds t the denminatr. Students wh answer ptins r may be making a randm guess. Remedial Measure: Students at this level, in general, are mre cmfrtable with 'half'. S it wuld be better t start with half, then mve n t and 4 ther fractins. The fllwing activity will help students t grup bjects apprpriately and identify the fractin f bjects in a cllectin. Give each student, r a grup f students multi-link cubes f different clurs. Ask them t make a twer f 4 cubes such that half the cubes in the twer are f the same clur. Ask them t justify that their twers have half the cubes f the same clur. Make twers f 4 cubes as shwn belw and ask them what fractin f the cubes in the twer are green. Page

4 Class 6 Math Teacher Reprt Fractins and Angles September 07 white cube green cube Let them ntice the rearrangement f cubes dne by yu t make ther twers. Help them see each f these twers have half the cubes green. Yu may als put cubes in a rw frming a blck and help them identify 'half'. In this way lead them t cnclude that the psitin f cubes in the twer r arrangement f cubes in a rw, dn't matter. In each f these cases, half the cubes in the cllectin are f the same clur. By this activity students will be able t see that cubes f the same clur is nt necessarily be tgether in the twer. Ask students t make twers with f the cubes f the same clur by giving them cubes f r mre different clurs and thus 4 help them cnslidate their learning. 4 Between which f these pairs f whle numbers des 4 lie? 4 between 0 and between and between 4 and 4 4 between 4 and 84 Critical Crrect Answer: Optin Optin Optin Optin 4 8% 6% 46% 0% Distractr Explanatin: T answer this questin crrectly, students shuld understand the cncept f imprper fractins and they shuld be able t cnvert imprper fractin t mixed fractin. Students wh have chsen ptin crrectly understd that 4 =, 4 4 which lies between and. Students wh have chsen ptin appear t have sme sense f the cncept, hwever, they pssibly feel that all fractins refer t a value f less than. Students als pssibly see a fractin as tw separate numbers, rather than as a frm f representing a single number. This is evident frm the significant prprtin f students wh have chsen ptin. Remedial Measures: Diagrams may be used t help students visually understand this cncept. Beginning with simple imprper fractins, demnstrate hw these can be changed int the frm f a mixed fractin. Ask them what fractinal number they wuld use t represent ne and a half pizzas, r tw and a quarter kg f rice, etc. Help them see that means + and therefre is a number between and. Help students represent different mixed fractins n a number line. Make them aware f why is the same as. Diagrams such as the ne shwn belw may be used whle and half halves ut f and whles Thus, help them realise that 4 can als be written + and that this number will therefre lie between and. 4 4 Page

5 Class 6 Math Teacher Reprt Fractins and Angles September 07 8 A trn paper has a crner as right angle. It is turned arund in psitins as shwn belw. Psitin Psitin Psitin In which f these psitins is the angle marked a right angle? nly Psitin all Psitins, and nly Psitins and nne f the Psitins, r 4 Recmmended Crrect Answer: Optin Optin Optin Optin 4 8% 7% 4% % Distractr Explanatin: Students wh have selected ptin knw that turning the paper t different psitins will nt change the angle marked s in all the psitins, the marked angle will remain t be a right angle. Students wh have selected ptin are able t identify a right angle nly when ne f its arms is hrizntal and the ther vertical. Students wh have answered ptin are nt able t identify a right angle in nn standard rientatins. Students wh have answered ptin 4 may have felt that the angle changes when the paper is turned. Remedial Measure: Help students understand angle as an amunt f turn by hw much shuld ne arm be rtated s that it cincides with the ther. Help them understand that this des nt change when the figure as a whle is rtated. Ask them t spt ut the right angles arund them - in the crner f a rm, r the angle between the edges f a bk etc. Let them make a paper cut ut f the letter L and actually place it alng these right angles t see if it fits. Slwly they can g n t making a mental cmparisn with the letter L t decide if an angle is a right angle. Make sure that yu expse them t right angles in all rientatins, s that they dn't frm fixed mental images like a right angle has ne arm hrizntal and anther vertical. Page 4
