How this resource helps
Add and subtract within 100: explain a strategy. This separate Grade 2 packet organizes an 80-minute lesson with 10-minute warm-up, 12-minute visual mini-lesson, 10-minute explicit model, 12-minute guided practice, 16-minute small-group/partner work, 15-minute practice, and 5-minute exit/closure. Includes four actual partner tasks, core and continuation student pages, an optional early-finisher challenge, detailed answer guidance, a quick evidence rubric, and targeted reteaching. Use core practice first; continuation is extra practice or reteaching, not a timed requirement. Quarter 1 is a publisher sequence label, not an official statewide pacing claim. Includes the current Saint Pierre Learning Resources logo and cover with the lesson title, verified learning focus, and contents. Printable US Letter PDF. The 9-page PDF contains a new cover plus the original eight numbered lesson pages. Printed page references are retained; numbered teacher page 8 is the ninth PDF page.

Standard or objective
I can choose, compare, and explain strategies for addition and subtraction within 100. NC.2.NBT.5: Demonstrate fluency with addition and subtraction, within 100, by: • Flexibly using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction. • Comparing addition and subtraction strategies, and explaining why they work. • Selecting an appropriate strategy in order to efficiently compute sums and differences. Lesson focus: flexible place-value strategies, efficient choices, and explanations. This lesson develops fluency; a single exit ticket does not establish full fluency. Current NC code verified October 11, 2026; the adopted 2026 revision begins classroom implementation in 2028–2029. This is focused lesson practice, not a claim of full-standard mastery.
