4.MP.3 Construct viable arguments and critique the reasoning of others. Use stated assumptions, definitions, and previously established results to construct arguments. Explain and justify the mathematical reasoning underlying a strategy, solution, or conjecture by using concrete referents such as objects, drawings, diagrams, and actions. Listen to or read the arguments of others, decide whether they make sense, ask useful questions to clarify or improve the arguments, and build on those arguments. Fourth grade students construct viable arguments to demonstrate their understanding of rounding procedures. Listen and look for students that exhibit the following behaviors: • provide complete and clear explanations of my thinking and work • decide if other students’ ex planations make sense; clarify or improve other students’ arguments • use counterexamples when appropriate. Sentence Frames: • My answer is different from ___________’s because _____________. • My answer is correct because _____________. Focus Standards Curriculum Supports – enVision 2020 Vocabulary

Strand: Numbers and Operations in Base Ten Fourth Grade students will be able to generalize place value understanding for multi-digit whole numbers by analyzing patterns, writing whole numbers in a variety of ways, making comparisons, and rounding. Standard 4.NBT.1 Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right . For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division. Standard 4.NBT.2 Read and write multi-digit whole numbers using base- ten numerals, number names, and expanded form. Compare two multi- digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
