End of Unit Competency

By the end of Topic 7 students will be able to justify solutions to word problems using addition and subtraction and evaluate for reasonableness.

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

● Mathematical terms ( model, reason, regroup, solution, equation, addition, subtraction ) ● Future tense doing verbs ( will count ) to recount steps ● Visuals ( tables, number line, bar diagram ) to support approach and/or solution ● Declarative statements to state conclusion ( Jacob needs 35 more beads. )
