They had a cake that was cut in the shape of a dump truck, a house for the little ones to paint, a deconstruction tower, and a spot where they could decorate their construction belts / favors.
Here's what they did.
The dump truck birthday cake was a simple sheet cake that they had baked in a special mold pan that was shaped like a dump truck. They colored the cake in typical construction colors: yellow, black, and brown.
It also had "dirt" Oreo crumbles around the tires and on the side saying "Happy Birthday Jerry!"
The first thing they did was before each kid entered the party they received a hard hat (Safety First!) and a small tool belt with toy tools, a little bit of candy and some construction themed stickers. Each belt had the child's name written on it in marker ahead of time.The hard hats were toy hard hats they bought online for less than $2 each and the belts were cut out of poster board.
Once all the kids were there, they were shown to a table where they could draw on the belts and make the belt their own.
After everyone was done customizing their tool belts it was time for some party games. The first activity was "build a house".
What they had done was gotten a large empty cardboard box (the kind a tv goes in) ahead of time from the local Walmart. They took the cardboard box and cut off the bottom and top flaps. Then they used duct tape to make a simple triangulated roof on top of the box using the extra cardboard flaps.
Then they provided things for the children to help them "build the house". They got really creative on the house with things like poster paint, markers, chalk, typical art supplies. It was a really fun activity and except for the cost of the art supplies and tape, it was a free activity!
Another game they did was a deconstruction tower, like a demolition tower. With a tennis ball attached to rope and looped over a tree branch, the goal was to knock over a tower of ten numbered cereal boxes starting backwards from ten. This was fun and educational, and loads of fun for the kids.
It did take one adult manning the deconstruction tower. They set the cereal boxes back up in between each kid's demolition attempt.
I was there to help the family set up some of the areas like the food bar, but I the children weren't over there much, they were too busy seeing who could knock down the tower the fastest, and making "renovations" to the house.
It was a really fun birthday and well suited for younger kids. The whole thing was really cheap too. The most expensive items were the hard hats, the construction birthday party decorations like plates and cups, and the food.
