Finding the Place Value of a 3-Digit Number in 3B
What a fun Maths lesson we had today 3 Blue! We found the place value of a 3-digit number and then challenged ourselves by finding 1, 10 and 100 less than a number.
What does the ’7’ represent in the 574?
What is 1 less than 326?
What is 10 less than 765?
What is 100 less than 244?
Seven represents 70 in the number 574 1 less than 326 is 325
10 less than 765 is 755 100 less than 244 is 144
Wow
What does the ’7’ represent in the 574?
The number 7 in 574 is ‘70’ therefore the number 7 represents ten.
What is 1 less than 326?
1 less than 326 is 325. I know this because 326 – 1 (unit) = 325.
What is 10 less than 765?
10 less than 765 is 755. I know this because 765 – 10 (tens) = 755.
What is 100 less than 244?
100 less than 244 is 144 I know this because 244 – 100 (hundred) = 144.
Great work Amirah.
