End of Unit Competency

By the end of Topic 4 students will be able to describe and model subtraction facts to 20 using strategies.

Language Functions and Features: Describe data and/or steps to solve problems using:

●​ Mathematical terms ( fact family, subtract, add, strategy, related facts ) ●​ Visuals ( pictures, number lines, ten frames ) to support approach, solution, and/or extract information ●​ Connectors to order steps ( first, next, then, finally ) and indicate reasons ( because, so, that means, as a result ) ●​ Declarative statements to state conclusion ( Addition and subtraction are related because…) ●​ Conditional clauses ( if, then ) to extend conjecture (eg . If 3 + 5 = 8, then 8 - 5 = 3 )
