3rd StandardMathematics
House of Hundreds - 1 - Chapter Summary
# House of Hundreds
## Overview
In this chapter, students explore large numbers (beyond 200) using various engaging activities like mela scenes, house numbers, number games, sweets packing, number lines, and Dienes blocks. The emphasis is on understanding place value, improving counting skills, and strengthening number comparison and patterns up to 3-digit numbers.

## Key Topics Covered
### 1. Counting Beyond 200
- Children count objects like triangular torans, bangles, and toffees.
- They estimate and verify quantities greater than 200 using groups of ten.
- Example: 250 triangles, 280 bangles, and 300 toffees.
### 2. Filling Number Patterns
- Students fill missing numbers in sequences like:
- 211, 212, ___, 216
- 294, 295, ___
- Understanding the logic of increasing or decreasing by 1, 2, 5, or 10.
### 3. Using Matchsticks for Place Value
- Representation of numbers using bundles:
- e.g. 235 = 200 + 35 = 2 Hundreds + 3 Tens + 5 Ones
- Students express numbers in different ways:
- 250 – 15 = 235
- 300 + 16 = 316
### 4. Number Lines
- Plotting and estimating positions of numbers on number lines.
- Exercises include:
- Finding numbers between 200 and 400
- Estimating distances from 400
- Jumping on number lines to visualize differences (e.g., 393 to 400)
### 5. Increase and Decrease Operations
- Changing numbers by adding or subtracting 1, 2, 10, 20
- e.g. 285 + 1 = 286, 147 + 10 = 157, 367 - 2 = 365
### 6. Guessing Games with Numbers
- Children guess a secret number in a range (e.g., between 200 and 210)
- Use of flags (left/right) to give clues about correct or incorrect guesses.
### 7. Magical Counting Game
- Write a number name, count letters in it, write name of resulting number.
- Example:
- "Two hundred and thirty five" → 23 letters → "Twenty-three"
- Repeats until it ends at “Four”
### 8. Sweets Count and Number Sentences
- Matching sweets to house numbers.
- Use of HTO format (Hundreds, Tens, Ones):
- Example: 211 = 2H + 1T + 1O = 200 + 10 + 1
