2nd Grade Math GRADE LEVEL STANDARDS/DOK PERFORMANCE ESSENTIAL SUGGESTED ACTIVITIES/ INDICATORS QUESTIONS/ ASSESSMENTS CONTENT/TERMS GRADING PERIOD Number Properties and Operations Whole number sense and addition and subtraction are key concepts and skills developed in early childhood. Students build on their number sense and counting sense to develop multiplication and division. They move flexibly and fluently through basic number facts, operations and representations. Their understanding of the base-10 number system expands to include decimals. They examine various meanings and models of fractions. They explore data, perform measurements and examine patterns as part of the development process for number and operations, using other mathematics strands to enrich number.
