Addition and Subtraction Within 1,000 with Word Problems to 100

EngageNY
Supporting grades: 2

Description: n Module 4, students developed addition and subtraction fluency within 100 and began developing conceptual understanding of the standard algorithm by means of place value strategies. In Module 5, students build upon their mastery of renaming place value units and extend their work with conceptual understanding of the addition and subtraction algorithms to numbers within 1,000, always with the option of modeling with materials or drawings. Throughout the module, students continue to focus on strengthening and deepening conceptual understanding and fluency. Topic A focuses on place value strategies to add and subtract within 1,000. Students relate 100 more and 100 less to addition and subtraction of 100. They add and subtract multiples of 100, including counting on to subtract. Students also use simplifying strategies for addition and subtraction. In Topics B and C, students continue to build on Module 4's work, now composing and decomposing tens and hundreds within 1,000.
