# One Easy Game For Adding Tens On A Hundreds Chart

Adding tens on a hundred chart is a great way for children to visually adding ten. This fun game with two levels gets children adding tens and ones, and then moves on to adding two-digit numbers using the 100’s grid and manipulatives.

I’m starting to see our efforts produce some fruit. My first grader has really struggled with place value, and I have been diligent to provide numerous opportunities for him play with and explore place value.

We have worked number puzzles on the hundreds chart.

Played games with expanded form.

Colored in pictures based on the worth of numbers.

And we have moved up and down the hundreds chart based on clues from clip cards.

It is working. He is beginning to understand what each number represents, but I know he still needs a little more exposure so today we will be playing a game using the 100’s chart.

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

## Prep-Work

With just a little cutting this game is ready to be played.

- First, print off enough game boards and record sheets (if using) for each player.
- Then print off one copy of the clues. I would recommend using cards stock paper.
- Next, cut out the clues.
- Finally, place the record sheets in sheet protectors, and gather up base ten cut-outs and dry erase markers

## Adding Ten on a Hundred Chart – How to Play:

There are two levels of this game, but whichever you choose your children will be working toward adding tens on a hundred chart.

#### Level One:

Level One simply has children adding tens and ones to the 100’s board until it is all filled up.

To play this game, make sure that you only have the clues that add tens and ones. You don’t want the cards that have 54 on them. This is for the next level.

First, students will draw a card and then make that number using the base ten block cut-outs (working on understanding the value of numbers). Then they put the base ten block cut-outs on the hundreds chart.

On the second time through, have the child predict what number the cutouts will cover up.

For example, if a child has covered up 23 numbers and they draw a 30……ask them what they think 20 + 23 is. If they don’t know that is fine.

But once they have added their two tens (we would slide down the ones and place the tens in-between), you can point out what they did.

Look, we are at 43. Do you see how the one’s place did not change? We added two tens and we went down two rows. What do you think would happen if we added one more ten?

It is through these questions, that children will begin to understand the 100’s chart and how to use it to be successful in adding.

#### Level 2:

This level has so many different types of learning in it, I won’t go into all the details.

- We worked on getting to 10 and then adding on from there.
- We practiced regrouping.
- My second grader was working on his mental math.
- They added and subtracted numbers in the tens.
- The value of the tens place and the ones place was discussed.
- And of course, we were adding tens on a hundred chart

With this level, we used all the cards and the recording sheet. But it is still played like the first level. My boys took turns drawing cards and adding or subtracting that number from their chart.

My oldest did the math in his head and then used the cut outs to check himself.

My first grade used his cut-outs to figure out the answer, and would then record it.

Here are a few things he worked on during this game:

#### Getting to 10:

In this example, my first grader needed to add 24. We discussed what he needed to do to get to 10. He looked at his board and reaized that 28 + 2 = 30.

So he added two ones to get him to 30.

From there, he was able to figure out that 30 + 12 =52. He added his cut-outs to show that he was correct and then recorded 28 + 24 = 52 on his record sheet.

#### Subtracting With Regrouping:

Another time he drew a subtraction card that required some regrouping. He had started with 52 and now was required to subtract 52. He knew he couldn’t do this because he didn’t have enough ones.

So he took a 10 out and counted out ten ones.

Then he took away six ones and three more tens to get the correct answer. 52 – 36 = 16

There was so much learning in this game. I watched as my kiddos built numbers, added tens and ones, and even subtracted. I know this background knowledge will provide useful as we focus more on adding and subtracting larger numbers!!!
