Day 2: Comparative Symbols
SnowWoman Construction Math
Comparing Snow Loads with Place Value Disks
1. Understanding Non-Proportional Models:
Building a SnowWoman involves comparing snow loads from different cranes. We can use non-proportional models like place value disks.
Example:
๐๏ธ1: 38 loads
๐๏ธ2: 95 loads
2. Decomposing Numbers:
Break down each number to understand its parts. Always start with the largest place value.
Example:
38 Decomposed:
3 tens + 8 ones
95 Decomposed:
9 tens + 5 ones
3. Comparing Place Values:
Good mathematicians always begin by comparing with the largest place value.
Example:
38 is less than 95 because:
3 tens < 9 tens
(Focus on the tens place first!)
4. Place Value Disks:
Use place value disks to represent the decomposition of each number. This visual aid helps us see the non-proportional differences in the snow loads.
5. Building with Place Value Disks:
Model building the snow loads using place value disks. This hands-on approach enhances our understanding of the construction process.
6. Comparative Symbols:
Use comparative symbols to show the relationship between the snow loads.
Example:
38 < 95
7. Reasoning:
Understanding why and how the numbers are different enhances our mathematical thinking.
Remember, when comparing numbers, decompose them into parts, focus on the largest place value, and use comparative symbols. This helps us make sense of the non-proportional differences in snow loads and construct the tallest SnowWoman! โ๏ธ๐ง๐ฝ๐๐ผ
