Shala Setu: Delhi Class 1 Subtraction Long Answer Guide

Start with the topic and teaching goal

This Shala Setu guide helps Delhi teachers plan a Class 1 Mathematics activity on Subtraction. Start from the school’s prescribed book, the topic already taught and the purpose of the task. The example here is original classroom practice, not a question copied from a prescribed textbook or an official board paper.

Understand Subtraction

Subtraction can show taking away or comparing quantities. Identify what the two numbers represent before calculating the difference.

Plan the long answer guide

Use a connected problem, explanation or evidence-based discussion. Define the expected structure and mark the reasoning as well as the conclusion. Adapt response length to the class and review whether the allocated time is realistic. Use concrete objects, short instructions and teacher support. Let students explain in familiar words before requiring a longer written response.

An original practice example

Question: There are 12 pencils. 4 are removed. How many remain?
Answer and explanation: 12 − 4 = 8 pencils.

Adapt the example to this topic

The practice example illustrates a response format or classroom check. Before using it, replace its details with a task that directly tests Subtraction in the actual chapter. For language work, use the prescribed passage or poem and name that text explicitly. For a numerical task, change the values only after checking that the method and answer remain valid.

Review marking and follow-up

Write the expected answer before giving the activity. Specify essential ideas, correct units or evidence where relevant and accept valid alternatives. After review, distinguish a missing concept from an incomplete explanation or a careless slip. Use a focused worksheet or reteaching step for the specific difficulty.

Official resources for Delhi

Confirm the board followed by the school and use SCERT material for its stated teaching purpose. Department resources and board requirements can serve different tasks. Confirm the class, subject, medium, session and document type on the official website. School tests and planning examples do not replace a prescribed syllabus or examination scheme.

Use Shala Setu for the next step

Create exam papers, worksheets and lesson plans through your account. The question bank includes MCQs, fill in the blanks, very short, short, long, essay, case-based and matching questions, as well as grammar, passages, prose and poems. For lesson plans, tick taught topics, complete the chapter to keep its record and share the reviewed plan with others.
