End of Unit Competency and Language Supports

By the end of Topic 12 students will be able to explain how to measure length. Language Functions and Features: Describe data and/or steps to solve problems using: ●​ Mathematical terms ( estimate, measure, inch, foot, yard, centimeter, meter, unit, length, height, precise, ruler ) ●​ Visuals ( drawings, rulers ) to support approach, solution, and/ore extract information

●​ Comparative language ( less than, more than, same as ) to share results ●​ Declarative statements to state conclusion ( Path B is longer because …) Evaluate others’ arguments using: ●​ Declarative statements to disagree/debate (eg. His estimate is precise because… )
