How this resource helps
Story problems within 20: find the unknown. This separate Grade 1 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 use objects, drawings, and an equation to find an unknown in a story. NC.1.OA.1: Represent and solve addition and subtraction word problems, within 20, with unknowns, by using objects, drawings, and equations with a symbol for the unknown number to represent the problem, when solving: • Add to/Take from-Change Unknown • Put together/Take Apart-Addend Unknown • Compare-Difference Unknown Lesson focus: change unknown, addend unknown, and difference unknown within 20. These are the problem types specified in NC.1.OA.1; result-unknown stories are used only as review. 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.
