Chapter 4: Vacation with My Nani Maa
3rd StandardMathematics
Vacation with My Nani Maa - Chapter Summary
# Vacation with My Nani Maa
## Overview
In this chapter, Chirag and Nandini visit their Nani Maa and learn various concepts of mathematics through day-to-day activities. The chapter focuses on building number sense, performing operations like addition and subtraction using number lines, tens frames, and other visual tools, and solving puzzles in a playful way. Students also explore estimation and logical thinking using number patterns and magic squares.
## Key Topics Covered
### 1. Hidden Numbers and Completing Totals
- Students observe objects (like seeds and marbles) and determine hidden quantities by subtracting visible items from the total.
- Practice: “You have 4 under your handkerchief” if 9 is the total and 5 are visible.
- Reinforces subtraction as a way to find unknowns.
### 2. Addition and Subtraction with Real Objects
- Real-life examples like balushahi, books, and magazines are used to add and subtract quantities.
- Example: 7 balushahi + 5 balushahi = 12 balushahi
7 balushahi – 5 balushahi = 2 balushahi
### 3. Using Tens Frames for Simple Calculations
- Visual method using tens frames to solve problems like:
- 6 + 8 = 14
- 9 – 6 = 3
### 4. Card Game for Addition and Subtraction Practice
- Make sets of cards numbered 1–10. When three cards make a valid addition or subtraction equation, the player collects them.
- Promotes mental math and logical reasoning.
### 5. Stamp Collection and Number Line Jumps
- Addition and subtraction of stamp collections:
- 15 + 7 = 22 stamps
- 22 + 30 = 52 stamps
- 52 – 37 = 15 stamps with monuments
- Students practice skip counting, decomposing numbers, and jumping strategies on number lines.
### 6. Frog and Grasshopper Jumping Game
- Visualize jumps of 10 forward or backward on number beads.
- Helps understand multiples of 10 and reinforces skip counting.
### 7. Grid Game
- Rolling dice to create two-digit numbers, and using number grid to move forward/backward.
- First player to reach a number between 91–100 wins.
- Encourages strategic addition/subtraction.
### 8. Fill the Table by Jumps
- Tables completed by jumping 5, 6, or 9 units ahead.
- Improves recognition of arithmetic sequences.
