The longer I've been teaching the less and less I use the math textbooks and worksheets. They rarely offer good activities and practice pages. So over the past two years I've been working on creating my own math curriculum. I like to make Smartboard lessons that go with my math unit so I can teach the concept and do activities and problems together as a class before I have the students work on the concept by themselves.

The math textbooks also never offer math center ideas so I was always having to search the internet, come up with ideas, and spend time making the centers so my students could have extra practice with the concept during center time. So I've compiled all my ideas together into one big math unit that I can easily plan and pull from each year.

Here is a look into some of the Smartboard slides, class activities and worksheets we do in class when learning how to add three numbers together.

I start my unit by going through Smartboard slides together as a class.

We learn different strategies on how to add three numbers together. We learn how to spot "doubles" in the problems.

We practice the concept using these practice pages.

We learn how to find 10 to add.

We also learn other strategies to add three numbers together such as using a number line and touch math.

Finally, we put all the strategies we learned together and practice, practice, practice!!

I like to have Smartboard slides, math centers, and/or practice pages that go together. It makes it so much easier for the students to know what to do at their center or on their practice page when we have gone through a similar activity together on the Smartboard. Here is a look into some of these activities...

We have fun spinning the dice and adding the three numbers together as a class on this Smartboard slide.

Then I have the students do the same activity at a math center.

They also do this independent practice page.

We go through this Smartboard slide together as a class.

Then, I have the students work on this page independently at their desk.

We play this Target Toss game on the Smartboard using a soft Koosh ball.

Then the students work on this similar independent practice page.

Here are some more of my math centers.

At this center the students flip three cards over and add the numbers together.

If they flip over an Ace it's value is 1. Any K, Q, or J flipped over is worth 10.

For the Addition Bump game each player gets 10 cubes of a color. They take turns rolling the three dice and adding the numbers together. They place their color cube on the sum on the game board. Another player can "bump" another cube off if they get the same sum. However, if a player rolls that sum twice they can lock the sum in with two of their cubes and they can no longer be bumped off of that space. The first player to use all 10 of their cubes is the winner!

Another pet peeve I have with a lot of the math textbooks is they sometimes only offer one or only a couple practice pages. I have made

*multiple*practice pages for the concept AND of various levels. Here is a look at some more of my practice pages we use during this unit...
These worksheets are good to use at the beginning of the unit or for students who still struggle with the concept.

Once we master adding three numbers together I take it to the next level by introducing story problems with three addends.

We go through various Smartboard example problems together as a class.

Then, I have multiple practice pages of story problems that we work together as a class or I have the students complete independently at their desk.

I end my math unit with various assessment pages. I use these pages to help me fill out the student's progress reports and report cards.
