TPACK-Model

Lesson no: 2
Grade: 3
Subject: Mathematics
Topic: addition

TPACK model:

• Technological Knowledge(TK): Use Power point presentations and digital simulations to visualize addition concepts and strategies.

• Pedagogical Knowledge(PK): Students will engage in collaborative learning activities and discussions to develop their understanding of addition strategies.
  
  
• Content Knowledge (CK): Students will understand the concept of addition and be able to solve addition problems within 20.

Lesson Objectives:

 By the end of the lesson, students will be able to,

• apply various addition strategies to solve problems within 20, as demonstrated through their ability to use manipulative, draw pictures, or count on mentally

• demonstrate increased confidence and enthusiasm in their ability to solve addition problems within 20, as evidenced by their active participation in class discussions and engagement with addition activities.
  

• demonstrate proficiency in  using digital tool  such as addition simulation software to visualize and practice addition concepts, as assessed by their ability to navigate the software and solve problems independently

Materials required :

• PowerPoint presentation
• Addition simulation software
• printed worksheets

Engage;addition ppt

• show a Power point  slide with an engaging visual representation of addition.
• ask students to share what they observe and what they think addition means.
• define addition as putting together or combining two or more numbers to find  a total. 
• engage students in a brief discussion about different ways they can add numbers together(e.g., counting on fingers, using counters, drawing a number line).

Explore;

• present a few simple addition problems on projector (e.g., 3+2=?). Have students solve problems using  manipulative.
• invite students to share their addition strategies with the class. discuss the effectiveness of different methods.

Explain;

• introduce use of hands-on activities as a tool for visualizing addition concepts. Provide students with sets of manipulative.
• demonstrate how to use the manipulative to model addition problems (e.g., using counters or blocks to represent numbers and then combining them).
• Guide students through several addition problems using manipulative, encouraging them to explain their thinking as they work.
• Provide feedback and clarification as needed

elaborate

• introduce digital addition simulation software to class.
• demonstrate how to navigate software and use it to solve problems.

• 
  allow students to explore the software independently practicing addition with various interactive tools and activities.
  
• encourage students to collaborate and discuss their strategies as they work through digital simulations.

Evaluate:

• Distribute printed worksheets with a variety of addition problems.
• Observe students as they work through the issues, observing how they use visual representations and manipulative to solve them.
• Provide feedback and assistance to individual students as needed, correcting any misconceptions or challenges.
• Facilitate a class discussion to reflect on the lesson,allowing students to share their experiences using addition manipulative and
• Provide feedback and assistance to individual students as needed, correcting any misconceptions or challenges.
• Facilitate a class discussion to reflect on the lesson,allowing students to share their experiences using addition manipulative and online tools for adding and subtracting fractions.
