Lesson Plan Title: Grade 1 Mathematics – Understanding Place Value with Tens and Units

1. Lesson Plan Title

Grade 1 Mathematics – Understanding Place Value with Tens and Units

2. Materials Needed

Base-10 blocks (or unifix cubes)
Place value charts
Number cards (0-9)
Whiteboard and markers
Worksheets with place value exercises
Small containers or bags

3. Learning Objectives

By the end of the lesson, students should be able to:
– Understand the concept of tens and units.
– Identify the place value of digits in a two-digit number.
– Group items into tens and units effectively.

4. Vocabulary

Place value
Tens
Units (ones)
Digit
Number

5. Previous Learning

Students should already be familiar with:
– Counting from 0 to 20
– Recognizing and writing numbers from 0 to 20
– Basic addition and subtraction using objects

6. Anticipated Challenges and Solutions

Confusion between units and tens: Use visual aids and hands-on activities to reinforce the concepts.
Difficulty in grouping items: Provide additional guidance and practice using manipulatives like base-10 blocks.

7. Beginning Activities (10% of time)

Duration: 5 minutes
– Introduction/Hook: Start with a brief discussion on what students already know about numbers. Ask questions like “What is your favourite number?” to engage them.
– Activity: Show students a pile of unifix cubes and ask them how many they see. Begin to group the cubes into tens and ones, explaining the concept as you go along.

8. Middle Activities (80% of time)

Duration: 35 minutes
– Direct Instruction (10 minutes): Use the whiteboard to write a two-digit number, e.g., 14. Explain that the ‘1’ is in the tens place, while the ‘4’ is in the units place. Use base-10 blocks to visually represent this number.
– Guided Practice (15 minutes): Distribute base-10 blocks and place value charts. Ask students to represent various numbers (e.g., 23, 31, 17) using their blocks and chart. Walk around to provide individual assistance as needed.
– Interactive Game (10 minutes): Divide students into small groups and give each group number cards and blocks. Call out a number and have each group quickly form that number using their cards and base-10 blocks. Rotate roles within groups to ensure every student participates.

9. End Activities (10% of time)

Duration: 5 minutes
– Review: Recap the lesson by asking a few students to come to the front and explain how they grouped their blocks for a given number.
– Closing: Summarize the key points of the lesson (tens and units) and answer any remaining questions.

10. Assessment and Checks for Understanding

Formative Assessment: Observe students during activities to monitor their understanding. Ask concept-checking questions during guided practice.
Summative Assessment: Administer a worksheet with place value exercises, where students will need to identify the tens and units in given numbers. Collect and review these for accuracy.

11. Differentiation Strategies

For Advanced Learners: Provide more challenging numbers (e.g., up to 50) and introduce simple addition and subtraction using tens and units.
For Struggling Students: Pair them with a peer buddy for guided practice and offer extra support through one-on-one assistance. Use more visual aids and repeat activities as needed for reinforcement.

12. Teaching Notes

Keep the lesson dynamic and interactive to maintain engagement, especially given the short attention span common in grade 1 learners.
Continually reinforce the place value concept with visual aids and real-life examples.
Be patient and provide lots of positive reinforcement to build confidence and encourage participation.
