Standard 1 Students use computational tolls and strategies fluently and when appropriate, use estimation. Benchmarks Recall all single-digit multiplication facts and their related division facts. Develop and use strategies, including mental arithmetic strategies, and invent algorithms to find products and quotients. Develop algorithms for fraction and operations. Choose appropriate computational procedures and tools to solve problems Use estimation to solve problems and determine reasonableness of results, and decide when it is more appropriate to estimate than compute.
Students interpret data using methods of exploratory data analysis.
Students pose questions and colect, organize, and represnt data to answer those questions. Benchmarks Describe how data collection methods can impact the nature of the data set. Explain the concept of representativeness of a sample. Describe the population based on a given sample. Propose and justify conclusions based on data.
