FLAME: Unit 4 builds confident understanding of teen numbers through clear, intentional, and developmentally appropriate instruction. Students learn the structure of numbers 11–19 and explore number 20, building a strong foundation for place value. This unit also introduces the Growing 100’s Chart (11–20), giving students repeated exposure to number patterns while engaging in hands-on activities that deepen their understanding.

Lessons follow the FLAME routine—subitizing, visual and auditory drills, number talks, counting practice, and a focused new concept or review. Mini-lessons gradually build subitizing skills for 6–10, supporting fluency as students move into teen numbers. Each week builds on the last, helping students move from concrete exploration to meaningful understanding of teen numbers.

Students will use their Growing 100’s Chart (1–20) to participate in interactive tasks, partner activities, and playful number routines that build confidence, flexibility, and early place-value sense.

This unit includes the full teacher manual, printable work mats, mini-lessons, assessments, and hands-on activities that support concrete learning and student engagement.

Perfect for teachers who want structured, consistent lessons that still offer flexibility, excitement, and joyful learning in the classroom.
