This Application Problem is a part of the Lesson 14, Unit 2, Grade 1. Sarah has 6 blue beads in her bag and 4 green beads in her pocket. She gives away the 6 blue beads and 3 green beads. How many beads does she have left? This problem again asks students to subtract 9 from 10 but from two different places: some from the green bead group and some from the blue bead group. Using numbers within 10, students can explore how it is sometimes more efficient to take from a particular group(s) when subtracting.
