Lesson Plan: Addition (Grade 1 Math)

Materials:

• Whiteboard or chart paper

• Markers or chalk

• Number cards (0-9)

• Manipulatives (e.g., counters, cubes)

Objectives:

• Students will understand the concept of addition.

• Students will be able to perform addition within 20.

• Students will practice solving addition problems using manipulatives and number cards.

Structure:

1. Introduction (5 minutes)

   • Engage students in a discussion about adding objects together.

   • Show examples of adding objects using visuals on the whiteboard or chart paper.

2. Introduction to Addition (10 minutes)

   • Explain the concept of addition using simple language and visuals.

   • Introduce the "+" symbol as a way to represent addition.

   • Give examples of addition problems orally and have students solve them using manipulatives.

3. Guided Practice (15 minutes)

   • Distribute number cards (0-9) to each student.

   • Display addition problems on the whiteboard (e.g., 2 + 3) and have students solve them using their number cards.

   • Encourage students to use manipulatives to represent the numbers and physically combine them.

4. Independent Practice (15 minutes)

   • Provide students with worksheets containing addition problems within 20.

   • Circulate the classroom to provide support and guidance as needed.

   • Encourage students to use manipulatives if they need assistance.

5. Wrap Up (5 minutes)

   • Review the concept of addition and ask students to share what they've learned.

   • Summarize the importance of addition in everyday life (e.g., counting money, measuring ingredients).

   • Collect worksheets for assessment.

Wrap Up: In this lesson, students learned about addition by using manipulatives and number cards to solve problems. They practiced adding numbers within 20 and gained a deeper understanding of the concept. By the end of the lesson, students should be able to solve basic addition problems confidently.

Curriculum Standards Met (Next Generation Learning Standards - Grade 1 Math):
