Find the Highest and Lowest Three-Digit Number

In this activity, we will be looking at the value of each digit in some three-digit numbers to find the highest or lowest number.

To find the highest number in the table, we first need to look at the hundreds (H) column.

In this case, we can see that every number has a 6 in the hundreds column, so we next look at the tens (T) column.

We can see that the highest digit in the tens column is 9, so 691 is the highest number.

Now let's look for the lowest number.

We know that each number has a 6 in the hundreds column, so we need to look at the tens column.

The lowest digit in the tens column is 2.

The lowest number in the table is 627.

If the hundreds and the tens were all the same, we would then look at the ones (0) column.

Does that make sense?
