Integration of Learning Outcomes
- Students will be able to use multi-steps to solve a variety of problems by making sense of problems and persevering in solving them, reasoning abstractly and quantitatively, attending to precision, looking for and making use of structure, and looking for and expressing regularity in repeated reasoning.
- Students will be able to add and subtract decimals by solving word problems.
- 5.NBT.7: Add and subtract decimals to hundredths; relate the strategy to a written method and explain the reasoning used.
