Number Concepts to 1,000,000
Numbers to one million extend place value to six digits. 347,852 means 3 hundred-thousands, 4 ten-thousands, 7 thousands, 8 hundreds, 5 tens, and 2 ones. Large numbers appear in real-world contexts: populations, distances, financial figures. The Tsimshian people of BC use three distinct counting systems (for animals, people and things) and the Tlingit name numbers using body-based logic (10 = two hands). These systems reveal that quantification is a universal human activity expressed through diverse mathematical frameworks.
Place value to one million
Each position is 10 times the position to its right. 100,000 = 10 x 10,000 = 100 x 1,000. Writing numbers with commas separating groups of three (347,852 vs. 347852) is a convention that helps readers parse large numbers quickly. In many European countries, spaces are used instead. The convention differs; the structure is universal.
Benchmarks for large numbers
500,000 is half a million: the midpoint of the 0-to-1,000,000 range. 100,000 is a hundred thousand: how many students in a large city school district? 1,000,000 is a million: roughly the population of the Metro Victoria area. Connecting large numbers to real contexts builds genuine number sense.
First Peoples counting systems
The Tsimshian people of BC use three distinct counting systems: one for animals, one for people, and one for objects/things. This is not three different number sequences but three different linguistic forms for the same quantities, reflecting the cultural significance of the things being counted. The Tlingit count to 10 as two hands, and group subsequent numbers accordingly. These systems show that counting conventions are cultural choices, not mathematical necessities.
