# Semester 1 Topic 7 Level E

 Task Name : Ordering Decimals Task Level : E (Grade 4) Semester : 1 Topic : Decimals and Percentages VC Strand : Fractions and Decimals Web Address : http://maths.crusoecollege.vic.edu.au/fdE Equipment Needed : Photocopies of tenths and hundredths squares. Poster paper. Victorian Curriculum outcome : Recognise that the place value system can be extended to tenths and hundredths. Make connections between fractions and decimal notation. Task description : Students choose six decimals between 0 and 1. Three need to have one decimal place and three need to have two. They then express these by shading in tenths and hundredths squares and then place them in order. A sentence needs to go between each explaining why one is larger than the other; for example, โ0.6 is larger than 0.57 because 0.6 has 6 tenths while 0.57 only has 5 tenthsโ. This can be shown in a poster. Assessment options : Photograph of models. Teacher notes : Some students who struggle with self-starting may spend an inordinate amount of time choosing their decimals. In this case, offer to choose them for the students. Bear in mind that the main misconception here is based on being unable to understand the place value: students may claim that 0.097 is larger than 0.61 because 97 is bigger than 61. Choose the decimals for the students with this misconception in mind. Downloads :ย Fractions and decimal squares
