Addition of 2 Digit Numbers

Main page

The topic/ concept ‘Addition of 2-digit number’ has been divided into three modules. Each module will be taught in a week. 

  1. Week 1 – Use base ten blocks to understand the concept of addition of two-digit numbers.
  2. Week 2 –  Use an abacus and draw place value models to show and solve addition problems involving two-digit numbers, with and without regrouping.
  3. Week 3 – Use different strategies to show and solve addition problems involving two-digit numbers, with and without regrouping, using the number line and procedural method.

The teachers are required to go through the document carefully before they start the class.

Developmental Goals as per NIPUN BHARAT

  1. Children Maintain Good Health and Well-being
  2. Children Become Effective Communicators
  3. Children Become Involved Learners and Connect with their Immediate Environment

Mapping Competencies under Developmental Goal 1

  1. Participate actively in hands-on addition activities using manipulatives and movement-based strategies.
  2. Develop fine motor skills while handling base ten blocks, abacus beads, and writing numbers.
  3. Show confidence and persistence while solving addition problems with and without regrouping.
  4. Demonstrate focus, patience, and cooperation during individual and group tasks. 

Mapping Competencies under Developmental Goal 2

  1. Use place value vocabulary (tens and ones) while explaining addition processes.
  2. Explain addition strategies clearly using base ten blocks, abacus, drawings, and number lines.
  3. Describe the process of regrouping in simple terms (e.g., “10 ones make 1 ten”).
  4. Express their thinking while solving problems and justify their answers.
  5. Listen to and follow step-by-step instructions during activities and discussions.

Mapping Competencies under Developmental Goal 3

  1. Apply addition skills in real-life situations (e.g., adding quantities of items, combining groups of objects).
  2. Relate addition concepts to everyday experiences through stories and practical activities.
  3. Explore and use different strategies (manipulatives, number line, procedural method) to solve problems.
  4. Demonstrate understanding of regrouping through real-life grouping and bundling situations.
  5. Show curiosity and problem-solving skills while working with two-digit numbers.

Preparation for the activities

Before the session:

  1. The teacher has to see the given LTM Videos and practice the correct procedure that has to be introduced.
  2. Teachers may download the LTM/ISL videos provided, to either teach or demonstrate them to the children while conducting the given activities.
  3. Teachers may ensure that all children can see the video when played and follow the activity as instructed.
  4. The teacher can use English and/or the native language while addressing the students.
  5. Students can be seated on their chairs/benches or on the floor. The teacher can stand in front of the class, near the blackboard or sit along with the children in a circle or facing them if they are sitting in a semicircle.
  6. Teachers go through the suggestions provided for variations and ensure necessary preparations are made accordingly.
  7. Teachers keep the required materials ready for conducting the different activities.
  8. The teacher plays the role of a demonstrator, facilitator and observer.

Preparing will help you to conduct an effective activity in an inclusive classroom and achieve the goal. 

Setting for an Inclusive classroom

Here are some adaptations that can be made to ensure that activities for enhancing reading and writing skills are accessible and inclusive for all students:

  1. Physical accessibility: Ensure that the area used for the given activity is accessible to all students, including those with mobility impairments. This may require rearranging furniture or additional seating options, such as cushions or chairs with back support.
  2. Communication: Consider the communication needs of all students in the classroom. Students with speech or language impairments may require Apps like AVAZ. 
  3. Visual aids: Teachers can download ‘Flashcards’ and make them embossed as shown in DIY videos, as visual aids benefit those who need visual cues.

Adaptations and Strategies for an Inclusive Classroom

The Variability of an Inclusive Environment needs to address the processing and attention differences of the learners. An inclusive environment may have learners with Visual Impairment, Hearing Impairment, Loco-Motor Impairment and Cognitive Differences.

Learners not only learn in different ways, but they also have unique motivations, interests, personalities and strengths. To address this variability, providing the appropriate adaptation is an effective solution.

To help in this process, some suggestions for adaptations are given here. The teachers are requested to go through the adaptations given and choose the appropriate one/ ones to follow according to the needs of the differences found among the students in a particular class.
