Playing on the hundreds chart builds number and place value sense. These hundreds chart riddles are a fun way for children to explore the hundred chart and review math vocabulary words like even and odd.

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.

After games, cut and paste activities, and puzzles we are moving on to some hundreds chart riddles to add a twist. And what I love about these riddles is that we will be reviewing terms like even and odd, greater than and less than, and even get in some adding and subtracting.

Hundreds charts are just one way to build number sense in our children.

This FREE email series will give you NINE 5-minute activities you can easily do every day.

## Prep-Work

With just a little bit of cutting, this activity is ready to go.

1. First, print off the hundreds chart and the riddle cards.
2. Next, cut them out. If you want to use them over and over you can laminate them.
3. Finally, gather up some dry erase markers.

## 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 student 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.
