My first grader and I have spent numerous hours on the hundreds chart. Math doesn’t come easy to this little guy, and so we use the hundreds chart to build number sense for him.

## How to Use the Hundreds Chart Riddles

### Before:

The hundreds chart riddle cards have some math vocabulary in them, so you may want to take a minute and review the words before you let your kiddos dig in. Here are a few of the vocab words used on the task cards.

- odd and even
- the signs > and <
- tens and ones
- more and less

### A Few Examples:

This card starts with asking the studentÂ to narrow down the hundreds chart and recognize that the number must be 81 to 99. Next, they get to narrow it down by understanding that the number cannot be an even number.

The last clue has children analyzing the tens and ones place and doing some subtraction. We know that the tens place is three more than the one’s place. This means we can cross off any number where the ones place is more than the tens…. 89. Then we subtract 8 – 3 to get a 5. Since 85 is an odd number, this is our answer.

### Sample 2:

In this case, we are looking for a number that is greater than 70. Then we have to find a number that digits equal 11, and have a 2 in the one’s place.

This can be solved in a couple of different ways. The student can simply go through and cross off all numbers that don’t have a sum of 11. Or they could cross off the numbers that don’t have a 2 in the one’s place. Once that is done, we can see that the only number that matches the clues is 92.

There is so much learning involved in these hundreds chart riddles. I hope you enjoy working through them with your kiddos.
