CAMBRIDGE PRIMARYMATHEMATICS 0845FRACTIONSSTAGE 3 (GRADE 2) 3Nn15 Understand and use fraction notation recognising that fractions are several parts of one whole, e.g.3/4 is three quarters and 2/3 is two thirds 3Nn16 Recognise equivalence between 1/2, 2/4, 4/8 and 5/10 using diagrams 3Nn17 Recognise simple mixed fractions, e.g. 1 1/2 and 2 1/4 3Nn18 Order simple or mixed fractions on a number line ,e.g. using the knowledge that 1/2 comes halfway between 1/4 and 3/4 and that 1 1/2 comes half way between 1 and 2 3Nn19 Begin to relate finding fractions to division 3Nn20 Find halves, thirds, quarters and tenths of shapes and numbers (whole number answers)My sincere thanks to :Ms Preeti Kaushik,our art teacher for designing and editing this unitMs Shruti Verma for maintaining the blogMr Madan Saini for reviewing this unitSuresh Goel(Director)Alliance World SchoolNoida , Delhi-NCR, India
