In this spring-inspired lesson plan, students’ understanding of subtraction will blossom. They will use spring-related counters and visual models to assist their subtraction skills.
Students will be able to subtract within 10 using spring themed objects.
The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

Introduction
(5 minutes)
Have five students come as a group in front of the class.
Say, “Okay, we have five students up the front. If I only want students wearing a shirt/sneakers, etc. How many people are wearing shirts/sneakers? How many people are not wearing shirts/sneakers? How many should we take away from the group?” (Tip: Have at least two students leave the group, one at a time.)
Ask, “Does the group have more or less people?”
Explain that when we subtract from a group of people, the number of people gets smaller, (as the group went from five to three people.
Tell them, “Today we will talk about how we can use spring objects to help us subtract, or take away, correctly.”
Beginning
Allow students to count in their home language (L1).
Have students use a thumbs up/thumbs down to signal more or less people in the group.
Review or define words such as smaller, bigger, and take away in both English and student home language (L1).
Intermediate
Invite students to turn and talk to share if they think the group has more or less people using the sentence frame, "The group has more/less people because ________."
