Find the missing group of ones.

The number is 308. It has three 100s. We need to find the number of ones. The number 308 can be broken apart, or partitioned, into the hundreds part and the ones part. We already know that the number has three 100s. So, we can write that in our place value chart. There are no 10s in 308, but there are eight ones. 308 has three 100s, no 10s, and eight ones. So, we can write the missing number. 308 has eight ones. The missing number was eight.
