Lesson Introduction: Exploring Place Value

A Magical Mystery Box

Objective:

To engage Year 2 students with the concept of place value in a fun and interactive way.

Materials Needed:

• A decorated box (the ‘Mystery Box’)
• A selection of objects (e.g., buttons, small blocks, toy cars)
• Whiteboard and markers
• Large place value chart (ones and tens)

Introduction Activity:

1. Begin with a Story: Gather the students in a circle and say, "Today, we are going on a treasure hunt! But this treasure is hidden in the Mystery Box. Inside, there are some special objects that will help us discover the secrets of numbers!"

2. The Mystery Box Revelation: Show the decorated Mystery Box and invite students to guess what could be inside. After a few guesses, open the box to reveal a collection of objects.

Example of Objects: 25 buttons, 14 building blocks, and 7 toy cars.

Engaging Questions:

• “How many buttons do you think we have?”
• “Can anyone find the total number of objects if we have 2 groups of 10 and some left over?”

Understanding Place Value:

As students express their guesses, introduce the idea of place value by saying, "In mathematics, we like to group numbers in tens and ones to understand them better, just like counting our treasures!"

Interactive Group Activity:

1. Grouping the Objects:

   • Invite students to help you sort the objects into groups of ten and ones using the large place value chart.
   • For example, 25 buttons can be grouped into 2 groups of ten (20) and 5 ones.

2. Discussion:

   • Discuss how the grouping shows us the number of tens and ones in a number.
   • Encourage students to create their own examples using the objects in the Mystery Box and write them on the whiteboard.

Conclusion:

End by stating, "Today, we have not only found some hidden treasures but also learned how to use groups of tens and ones to understand the exciting world of place value!"
