					Using Assessment to Meet Individual Needs
					
					The explicit Expectations and assessment tasks in this unit
						describe what it means to "get it." Providing feedback on these
						Expectations helps identify students who need to access the
						content another way, need further practice opportunities, or are
						ready to extend or deepen their understanding of a concept.
						Instructional opportunities that help support the varied needs of
						students also need to be identified. These opportunities provide
						models that can be replicated or used multiple times and can be
						used in a variety of settings (e.g., home, transitions, support
						classroom, as a center).
					
				 
				
			 
			
			
			
			
				
					
					
						The Assessment Program serves the 
following purposes:
					
					
						- It provides information to teachers about what students
							know and can do. This information is used to guide instruction.
							An activity may help teachers answer questions about whole-class
							instruction: What do I do next? In the next minute? Next lesson?
							Next class? Next unit? Other assessments may help teachers decide
							how to support individual students, including those who struggle
							with a concept and those who are ready to be challenged.
 
						- It communicates the goals of instruction to parents and
							students. What teachers choose to assess communicates to the
							class what they value. For example, if teachers want students to
							work hard at communicating problem-solving strategies, then it is
							important to assess mathematical communication.
 
						- It provides feedback to students and parents about
							student progress. This includes teacher evaluation of student
							progress as well as students' assessment of their own progress.
 
					
				 
				
			 
			
		 
		
	 
	
	
	
		
		Key Mathematical Ideas
		
			The mathematical content in Math Trailblazers is organized
			around a set of Key Ideas. These Key Ideas are based on the National
			Council of Teachers of Mathematics (NCTM) Standards for the
			grade band as well as current thinking in the mathematics education
			community, e.g., Charles (2005), NCTM (2000), Van de Walle (2013).
			There is a set of Key Ideas for each content strand: Number, Algebra,
			Geometry, Measurement, and Data. They are based on "big ideas" in
			mathematics and describe what students should be able to do within
			each strand. The Key Ideas are shown in the table in Figure 1.
		
		
			
				
			
			
				
					
					
						
							
								| 1. Number Sense:
									Understand the base-ten number system, recognize relationships
									among quantities and numbers, and represent numbers in multiple
									ways. | 
								2. Operations: Understand the meaning
									of numerical operations and their application for solving
									problems. | 
								3. Computation and
										Estimation: Use efficient and flexible procedures to compute
									accurately and make reasonable estimates. | 
							 
						 
					 | 
				
				
					
					| 1. Identifying Patterns:
						Identify and describe patterns and relationships, including how a
						change in one variable relates to a change in a second variable. | 
					2. Tables and Graphs:
						Represent patterns and relationships with graphs, tables, and
						diagrams. | 
					3. Symbols:
						Represent patterns and relationships with symbols (includes using
						variables in formulas and as unknowns in equations). | 
					4. Using
							Patterns: Apply relationships, properties, and patterns to solve
						problems, develop generalizations, or make predictions. | 
				
				
					
					| 1. Shapes: Identify, describe, classify,
						and analyze 2- and 3-dimensional shapes based on
						their properties. | 
					2. Orientation and Location: Use
						coordinate systems to specify locations and describe spatial
						relationships. | 
					3. Motion: Apply transformations (slides,
						flips, and turns) and use symmetry to analyze mathematical
						situations. | 
					4. Geometric Reasoning: Use
						visualization, spatial reasoning, and geometric modeling to solve
						problems. | 
				
				
					
					| 1. Measurement Concepts:
						Understand measurable attributes of objects or situations (length,
						area, mass, volume, size, time) and the units, systems, and
						processes of measurement. | 
					2.
							Measurement Skills: Use measurement tools, appropriate
						techniques, and formulas to determine measurements. | 
				
				
					
					| 1. Data Collection: Select, collect, and
						organize data to answer questions, solve problems, and make
						predictions. | 
					2. Data Representation: Select and create
						appropriate representations, including tables and graphs, for
						organizing, displaying, and analyzing data. | 
					3. Data Description: Describe a data set
						by interpreting graphs, identifying patterns, and using
						statistical measures, e.g., average and range. | 
					4. Using Data: Apply relationships and
						patterns in data to solve problems, develop generalizations, and
						make predictions. |

		Expectations
		To monitor students' growth across and within grades, there are
			a set of Expectations that describe what students are
			“expected” to do within each content strand. Expectations
			show the growth of the mathematical content within the Key Ideas for
			each strand.
		
			
				
					| EXPECTATIONS | 
				
			
			
			
				
					 | 
					Use this list of Expectations to assess students on the
						key concepts and skills in this unit. | 
				
				
					| E1* | 
					Represent two-digit and three-digit numbers using base-ten
						pieces, number lines, and symbols. | 
				
				
					| E2* | 
					Compose and decompose numbers using ones, tens, and
						hundreds. | 
				
				
					| E3* | 
					Show and recognize different partitions of numbers using
						different representations (base-ten pieces, number lines, number
						sentences). | 
				
				
					| E4 | 
					Make connections between place value concepts and
						representations of numbers (e.g., base-ten pieces, number lines,
						number sentences, symbols). | 
				
				
					| E5* | 
					Recognize that different partitions of a number have the
						same total (e.g., 50 + 4 = 40 + 14). | 
				
				
					| E6 | 
					Estimate a quantity using 10 and 100 as benchmarks. | 
				
				
					| E7 | 
					Use words and symbols (e.g., <, >, =) to show comparisons
						of quantities. | 
				
				
					| E8 | 
					Compare and order three-digit numbers using base-ten
						pieces and a number line. | 
				
				
					| E9 | 
					Tell and write time from an analog clock to the nearest
						five minutes. | 
				
				
					| E10* | 
					Demonstrate fluency with the addition facts in Groups C (1 + 9, 2 + 7, 2 + 8, 2 + 9, 
					3 + 6, 3 + 7, 3 + 8, 4 + 6, 4 + 7, 5 + 5, 5 + 6)
						and Group D (3 + 3, 3 + 4, 4 + 4, 4 + 5, 6 + 6, 6 + 7, 7 + 7, 7 + 8, 8 + 8,
						10 + 4, 10 + 10). | 
				
				
					| E11* | 
					Determine the unknown number in an addition or subtraction
						sentence relating three whole numbers for the facts in Groups C
						and D. | 
				
				
			
		
	 
	
	
	
	
	
	
	
	
	
	
	
	
	
	
	
		
		Targeted Practice
		This unit provides opportunities for additional targeted
			practice for some of the Expectations. See the chart in Figure 3 and
			the descriptions that follow. These opportunities connect directly to
			assessment tasks, so the practice can be tailored to the current
			level of student progress.
		
			- For students who are struggling with the Expectation,
				practice is targeted toward the foundational concepts and skills
				involved and often provides a different way to access the content.
 
			- For students who are making significant progress toward the
				Expectation, practice is designed to help move toward proficiency
				and autonomy.
 
			- For students who are already meeting the Expectation,
				opportunities are provided to deepen or extend understanding.

		Workshop
		Much of the targeted practice is in Lesson 7 Workshop: Place
			Value Concepts, which provides a menu of activities that revisit key
			concepts and skills developed earlier in the unit. Based on students'
			self-assessment of their confidence with Expectations, students
			select activities from a Menu. See Figure 4. Teacher guidance can
			help students find the appropriate level of practice.
