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 ( frst, 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
