My Funday: CBSE Class 2 Maths Chapter 9 Guide

The Seven Days of the Week

There are exactly 7 days in a single week. The cycle always starts with Monday, followed by Tuesday, Wednesday, Thursday, Friday, Saturday, and finally Sunday! Every week repeats this exact same pattern over and over. To understand how these days work together, we use words like Today (the day we are in right now), Yesterday (the day that passed just before today), and Tomorrow (the next day that will come). For example, if today is Wednesday, then yesterday was Tuesday because it came right before Wednesday. Tomorrow will be Thursday because it comes right after Wednesday. Thinking of the days like a train where Monday is the engine and Sunday is the last coach makes it super easy to remember! Let's practice moving forward and backward along this train.

How to Find Yesterday and Tomorrow

1. Step 1: Find Today — Identify the day you are on right now. This is your starting point on the calendar.
2. Step 2: Go Backward for Yesterday — Move exactly one day backward on your weekly calendar. For example, if today is Monday, taking one step back brings you to Sunday.
3. Step 3: Go Forward for Tomorrow — Move exactly one day forward from today. If today is Monday, taking one step forward brings you to Tuesday.

Understanding Months and the Year

Months in a Year

There are 12 months in a full year, starting with January and ending with December. They help us track seasons and years.

Days in a Month

Different months have different numbers of days. Some months have 30 days, some have 31 days, and February has 28 (or 29 in a Leap Year).

Leap Year

A special year that happens once every 4 years where February gets 1 extra day, making it 29 days long instead of 28.

The Magic Knuckle Shortcut

Struggling to remember which months have 31 days and which have 30 days? Close your hand into a tight fist! Now, look at your knuckles. Count the months by pointing to your knuckles (high bumps) and the spaces between them (valleys).

• Knuckle (Bumps): January, March, May, July, August, October, December. All of these have 31 days!
• Spaces (Valleys): February, April, June, September, November. These have 30 days (except February, which has 28 or 29 days).

This simple trick ensures you never make a mistake on your maths worksheets!

Practice Questions with Solutions

• Q: If today is Sunday, what day was yesterday, and what day will it be tomorrow? A: Step 1: Identify the starting point. Today is Sunday. Step 2: Find yesterday by going backward by 1 day. The day before Sunday is Saturday. Step 3: Find tomorrow by going forward by 1 day. The day after Sunday is Monday. Final answer: Yesterday was Saturday and tomorrow will be Monday.
• Q: If Monday is the first day of the week, which day is the fifth day of the week? A: Step 1: Count the days in order starting from Monday. Step 2: Let's list them down: - 1st Day: Monday - 2nd Day: Tuesday - 3rd Day: Wednesday - 4th Day: Thursday - 5th Day: Friday Step 3: Identify the 5th day from your list. Final answer: The fifth day of the week is Friday.
• Q: List all the months of the year that have exactly 30 days. A: Step 1: Recall the months of the year and use your knuckle trick to check the days. Step 2: Filter out the months with 31 days and February (which has 28/29 days). Step 3: The remaining months with exactly 30 days are April, June, September, and November. Final answer: April, June, September, and November have 30 days.
• Q: Neha has her drawing class every Wednesday. If today is Monday, how many days must she wait to attend her class? A: Step 1: Identify today's day, which is Monday. Step 2: Count the steps forward to reach Wednesday: - Monday to Tuesday is 1 day. - Tuesday to Wednesday is 2 days. Step 3: Neha must wait 2 days to reach Wednesday. Final answer: Neha must wait 2 days.
