End of Unit Competency

By the end of Topic 9 students will be able to justify a strategy(s) to prove the solution to an addition and/or subtraction problem.

Language Functions and Features:

Generalize commonalities and differences using: ●​ Conditional clauses (when, if) to extend conjecture (eg. If you compare the sum to my conjecture, then… )

Justify conclusion using: ●​ Connectors to order steps ( first, next, then ) and indicate reasons ( because, so, that means, as a result ) ●​ Technical nouns and noun groups to add details ( conjecture , sum, regroup, difference, estimate, reasonable ) ●​ Patterns or rules and visuals ( charts ) to support solutions and demonstrate thinking
