This week in math class, we practiced how to take numbers up to 9 digits long and put them in expanded form.
Ex. 983,406 ---> 900,000 + 80,000 + 3,000 + 400 + 6
We also looked at expanded form and how to take it down to numeric form. I also showed an algebraic way of doing it, which students really go into!!
Ex. (3x100,000) + (2x10,000) + (7x1,000) + (4x100) + (5x10) + (8x1) ---> 327,458
300,000 + 20,000 + 7,000 + 400 + 50 + 8 ---> 327,458
On Thursday, we began comparing numbers. When comparing, we know that we need to look at the greatest place value position first. If the digits are the same in both numbers, we then work to the right until one of the digits is different. That is when we know one is greater or less than the other!
Next week we will work with adding and subtracting numbers up to 9 digits!
Math logs will begin next week. Students will be expected to complete 10-20 minutes of Reflex next week. My username is lisahoward122.
