They practicee applying theeir know wledge of cen ntimeters and d meters to choose an app propriate meaasurement to ool in Lesson 6. Students discover that the ere is a relatio onship between unit size and measurem ment when th hey measure one object tw wice usin ng different le ength units. TThey learn thaat the larger tthe unit, the ffewer numbeer of units in aa given meaasurement. In n Lesson 7, sttudents continue to measu ure and comppare lengths u using standarrd and non‐ stan ndard length u units. At this point, studen nts are prepaared to explic itly compare different non n‐standard lenggth units and can make infferences abou ut the relative e size of objeccts.
