Content Standards: Standard 2.NBT.5 Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction. Standard 2.OA.1 Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing with unknowns in all positions by, for example, using drawings and equations with a symbol for the unknown number to represent the problem.

End of Unit Competency and Language Supports

By the end of Topic 6 students will be able to justify solutions to subtraction equations fuently within 100.

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

● Mathematical terms ( partial difference, model, equation, subtract, break apart ) ● Visuals ( place-value blocks, bar diagram ) to support approach and/or solution ● Declarative statements to state conclusion ( The difference of 52 and 34 is 18. )
